Technical Field of Invention
[0001] The present subject matter relates to a vehicle with an electric propulsion system supported by an energy storage system.
Background 5
[0002] A vehicle with two, three, or four wheels may be propelled by any number of propulsion means. The most common types of propulsion means are an internal combustion engine, which generates power for propulsion by combusting a hydrocarbon-based fuel in a cylinder, which generates exhaust gases, pushing down on a piston translating the combustion into a forward motion. Such vehicles usually 10 have a fuel storage unit mounted securely on the vehicle itself. Another method is to have a rechargeable electric power storage unit onboard, which powers one or more electric motors, which drive one or more wheels of the vehicle. The electric motors may be mounted on a wheel hub itself, or on an axle, or on a frame of the vehicle, and be connected to the wheel through a shaft, a chain, or a belt. There are 15 also other power sources to drive a vehicle, such as a hydrogen fuel cell. The vehicle can also have a hybrid propulsion system, which is a combination of at least two of the known propulsion systems in vehicles. The most commonly used hybrid powertrains of vehicles are a combination of the internal combustion engine and the electric motor. Such a vehicle would require a storage for the hydrocarbon fuel 20 as well as an electric power storage unit. An entirely electric vehicle will have one or more electric power storage units, also known as batteries, to power the one or more electric motors. Such batteries must have a high charge density and a high charge capacity, in order to ensure maximum utilisation of the vehicle, and maximum available range for the user of the vehicle. Such batteries are usually 25 made with Lithium ion (Li-ion) cells, which have a very high charge density compared to other types of known cells (such as Lead Acid).
[0003] Historically, the application of electric powertrains in vehicles has been limited by the capacity of the existing batteries to power the electric motor for extended periods of time. Li-ion cells are currently the most commonly used battery 30 cells in the automotive and other industries due to their high charge capacity and
3
density. Compared to other existing battery cells, the Li-ion cell provides a higher range of operation for the vehicle due to its high charge capacity. Also, with the development of faster charging ports, the viability of electric vehicles are increasing. [0004] However, such batteries comprising Li-ion cells generate a lot of heat when 5 charging or discharging. Appropriate heat dissipation methods also have to be arranged around the battery for the same. This heating can damage the cells, and generally affects the life and longevity of the cells in the battery. In existing battery packs, it is usually very difficult to replace a single cell as the packaging of the cells is done by taking into consideration various factors, including but not limited to 10 electrical connections, heat dissipation mechanisms, and external cooling mechanisms. Heating of a Li-ion cell can lead to a failure mode of the Li-ion battery known as thermal runaway. Li-ion thermal runaway occurs when heat generated by a cell exceeds the amount of heat being dissipated, which causes a chain reaction in the form of propagating thermal runaway in surrounding Li-ion cells and batteries. 15 In order to protect a battery from such an accident, there are various levels of protections designed into the battery systems. They can be broadly classified into three levels of protection, cell-to-cell, module-to-module, and battery pack level. Cell-to-cell protection involves designing a material to go between the individual cells so that heat in one cell is not transferred to the neighbouring cells. One of the 20 most effective and common methods of protection at the cell level is by using phase changing materials (PCMs). There are several materials which are designed to be placed between cell modules depending on size and design. Thermal runaway may occur within a module but it can be contained therein, and prevented from spreading to the next module in the battery pack. This protection method generally allows 25 weight saving within the battery pack. Pack level protection is a means of protection against the thermal runaway in the entire battery pack.
[0005] Almost all Li-ion cells are susceptible to thermal runaway. Each cell in a Li-ion battery contains a flammable electrolyte, which can combust under extreme heat. The pressure within the cell will rapidly increase until the cell vents the 30 electrolyte. Temperature of the ruptured cell(s) can reach up to 1000 degrees
4
Celsius. Thermal runaway usually produces smoke or fire, and in some cases is known to have causes explosions as well. The users of the vehicles in such a case therefore need to have as much time as possible to escape the vehicle. Also, the users must be protected against the direct impact of the explosion, if it does occur. In light of the dangers of the explosions caused by thermal runaway, regulation has 5 been introduced in various jurisdictions to implement homologation standards across all battery packs to ensure the safety of the user of the vehicle. As a security feature, existing battery packs are provided with thermal runaway valves. These valves are designed to disintegrate in the even of build up of explosive gases and liquids within the battery pack, so that the battery pack itself does not explode, 10 which could potentially be more harmful, depending on the disposition of the battery pack itself in the vehicle. [0006] It is known in the art that in a four wheeled vehicle, a battery pack may be stored below the passenger seating compartment to achieve a low centre of gravity for the vehicle. It is also known in the art that in a two wheeled vehicle with a step 15 through type frame, existing battery packs are known to be disposed below the footboard. Additional battery packs are also known to be disposed below the rear seat in such vehicles. In two wheeled straddle type vehicles however, disposing the battery pack becomes a challenge. Problems are known to exist in such design which cause problems during daily operation as well as during servicing. Users of 20 such vehicles often face poor handling. Also, the serviceability of the battery and the connectors / couplers of the battery is poor in such existing designs. Also in such existing designs, the battery pack itself may or may not have a thermal runaway valve.
[0007] In view of the above, there is a need for a vehicle having a straddle type 25 design such that the battery pack is mounted on the vehicle in such a way that the thermal runaway valve be disposed in such a manner that the gases and liquids being projected out of the valve are directed away from the user of the vehicle, further reducing the risk to the user of the vehicle in case of thermal runaway in the battery pack. 30

Detailed Description
[00028] Various features and embodiments of the present invention here will be discernible from the following description thereof, set out hereunder.
[00029] Figure 1 is an exemplary illustration of a partially shown vehicle frame, including a headtube 101 and one or more down frame members 102, and mounting 25 of one or more energy storage device(s) 106 with respect to the vehicle frame, in a vehicle 100 front rear direction, from a side view of the vehicle 100. In this exemplary illustration, a two wheeled straddle type vehicle 100 is being considered. The frame of the vehicle 100 comprises the head tube 101, and the one or more down frame members 102. The one or more down frame members 102 in the 30
8
vehicle 100 generally extends rearwards, substantially in horizontal direction from the headtube 101, depending on the type of frame being designed for the particular vehicle. In this exemplary embodiment, the one or more down frame members 102 extends substantially horizontal in rearward direction, and then bends and extends rearwardly in downward direction. Also, as per an embodiment of the present 5 subject matter, the one or more down frame members 102 of the vehicle 100 includes two arms, namely a first arm down frame member and a second arm down frame member (not shown), which first extends substantially horizontal in rearward direction from the headtube 101 forming an acute angle with the headtube 101, and then extend in downward substantially in vertical direction. The two arms of the 10 one or more down frame members 102 being substantially parallel to each other. Also, as per the current exemplary embodiment of the present subject matter, the vehicle 100 includes a front wheel 110, which is attached to the vehicle frame through a vehicle suspension system 108. A steering column (not shown) is attached to a handlebar (not shown), which is operated by the user of the vehicle. The 15 steering column passes through the headtube 101 and is connected to the suspension system 108 of the vehicle 100 through a lower bracket 107. The front wheel 110 is further equipped with a brake system 109. As per an embodiment, the brake system is a disc type brake. In another embodiment of the present subject matter, the brake system 109 is a drum type brake. 20 [00030] In the present embodiment, the vehicle 100 contains one or more energy storage devices 106. The one or more energy storage devices are disposed behind the at least one front wheel 110. Further, the one or more energy storage devices are disposed below the one or more down frame members 102. Each of the one or more energy storage devices 106 is configured with a thermal runaway valve 111. 25 The thermal runaway valve 111 is placed
at an apogee of a frontmost corner on each of the energy storage devices 106. This is done so that in case of the rupture of the thermal runaway valve 111, the gases and the liquids coming out of the energy storage devices 106 are directed away from the user of the vehicle 100, and also away from the other electrical and electronic components of the vehicle 100. As per 30 an embodiment of the present subject matter, the other electrical and electronic
9
components of the vehicle, such as a battery management system, an inverter, and charging means are disposed behind the energy storage devices. The vehicle 100 further comprises a battery holding structure 104. The battery holding structure 104 is configured for mounting the one or more energy storage devices 106 below the one or more down frame members 102. The battery holding structure 104 is 5 mounted to the one or more down frame members by at least two mounting means 103a, 103b. The two-mounting means 103a, 103b are located at two ends of the one or more down frame members 102. The holding structure 104 and the one or more down frame members 102 forms a space in which the one or more energy storage devices 106 is disposed. As per an embodiment of the present subject matter, there 10 is at least one battery holding structure 104 on each side of the vehicle 100 in a vehicle 100 widthwise direction. The battery holding structures 104 are then structurally connected with a floorboard (115L, 115R) of the vehicle100. As per an embodiment of the present subject matter, a lower portion of the battery holding structure 104 is also configured to support the floorboard (115L, 115R) of the 15 vehicle 100. As per this embodiment, the battery holding structure 104 is configured such that a lowermost portion of the energy storage device 106 is disposed below the topmost portion of the floorboard (115L, 115R). As per the present embodiment of the subject matter, the one or more energy storage devices 106 are further secured with a battery cradle 105. The battery cradle 105 is configured to securely mount 20 the energy storage devices 106 on the battery holding structure 104. [00031] Figure 2 is an exemplary illustration of the disposition of the thermal runaway valve(s) 111 on the energy storage device(s) with respect to a front wheel 110 of the vehicle 100, in a vehicle 100 widthwise direction, from a front view of the vehicle 100. More specifically, this figure shows the vehicle 100 front view at 25 the level of the front wheel 110. The steering column passes through the headtube 101 and gets connected to the front wheel 110 through the suspension system 108 of the vehicle 100. The suspension system 108 is connected to the steering column through the lower bracket 107. The one or more energy storage devices 106 are also visible. According to the present embodiment, there is at least one thermal runaway 30 valve 111 on each of the energy storage devices 106. The thermal runaway valve
10
is disposed
at an apogee of a frontmost corner of said energy storage device (106). From this front view of the vehicle, it can be seen that the location of the thermal runaway valves 111 on the energy storage devices 106 is in line with a gap between the lower bracket 107 and the topmost part of the front wheel 110. This provides an advantage, that if the thermal runaway valve 111 ruptures, the gases and liquids 5 escaping from the thermal runaway valve 111 are directed away from the user of the vehicle 100 through this gap. The one or more energy storage device 106 are disposed lengthwise in the vehicle 100 front rear direction, such that the energy storing devices 106 disposed therein are parallel to each other. In the present embodiment of the subject matter, this makes it easier to mount electrical and 10 electronic connectors, at the back of the energy storage devices 106. Further, if the valve ruptures, these electrical and electronic connectors, as well as other devices disposed at the back of the energy storage devices 106 will also not be affected by the gases and liquids. [00032] Figure 3 is an exemplary illustration of the vehicle frame, including the 15 headtube 101 and the one or more down frame members 102, and the mounting of the energy storage device(s) 106 with respect to the frame of the vehicle, and the disposition of the thermal runaway valve(s) 111 on the energy storage device(s) 106 with respect to the front wheel 110 of the vehicle 100, in the vehicle 100 front rear direction, in an isometric orientation of the vehicle 100. This orientation of the 20 vehicle 100 clearly shows the battery holding structure 104 and the battery cradle 105. The battery holding structure 104 is mounted on the frame at a first mounting means (not shown). From this mounting point, where the first mounting means 103a, the battery holding structure descends angularly downwards for a first portion (104UB) of the descent of the battery holding structure 104, and then vertically 25 downwards for a second portion (104UA) of the descent of the battery holding structure 104. The first portion and the second portion of the battery holding structure 104 together form an upper portion 104U of the battery holding structure 104. At the end of the upper portion of the battery holding structure 104, the structure 104 bends rearwards, and extends substantially horizontally to its second 30 mounting location, the second mounting location being at the second mounting
11
means 103b. The battery holding structure 104 supports the battery cradle 105. The battery cradle 105 is configured to securely mount the one or more energy storage devices 106 on the battery holding structure 104. The battery cradle105 secures the contours of the energy storage devices 106 disposed parallel to each other along the length and the width of the one or more energy storage devices 106. A part of the 5 battery cradle 105 travels over a top portion of the one or more energy storage devices 106 and is joined to the cradle 105 along the length of the energy storage devices 106. As per an embodiment, the lowermost portion of the energy storage devices 106 is below the topmost portion of the floorboards (115L,115R) (shown in figure 4(b)). In figure 3, it is shown that the energy storage devices 106 are 10 mounted at a plane lower than the lower portion of the battery holding structure 104. A further securing means (not shown) along the bottom of the energy storage devices are configured as per this embodiment of the present subject matter. [00033] Figure 4(a) is an exemplary illustration of a partially shown front portion of the vehicle 100, in a vehicle front rear direction, from a side view of the vehicle 15 100. This illustration shows one or more body panels of the vehicle 100 in the vicinity of the front wheel 110 of the vehicle 100, along with a left side floorboard 115L of the floorboard (115L,115R) on a left side of the vehicle 100, as well as the rider’s seat 114. As per an embodiment of the present subject matter, the rearmost portion of the one or more energy storage devices 106 are in line with the frontmost 20 portion of the rider’s seat 114. It is also a feature of the present subject matter that the energy storage devices 106 are disposed behind the front wheel 110 in a vehicle front rear direction. The left side floorboard 115L of the vehicle 100 on the left side is also shown in this figure. As per an embodiment of the present subject matter, the lowermost portion of the one or more energy storage devices 106 are situated 25 below the topmost portion of the floorboard 115L when the one or more energy storage devices 106 are mounted on the vehicle 100. Further, two imaginary planes (A-A’ and B-B’) are marked on the vehicle 100. The first imaginary plane (A-A’) is a cross sectional plane which passes near the lower bracket 107, and is disposed above the topmost portion of the one or more energy storage devices 106. The 30 second imaginary plane (B-B’) passes through the topmost point of the front wheel
12
110. The thermal runaway valves 111 disposed on the one or more energy storage devices 106 lie between the first imaginary plane A-A’ and the second imaginary plane B-B’. [00034] Figure 4 (b) is an exemplary illustration of the vehicle from a top view of the vehicle, in a vehicle front rear direction. From a top view of the vehicle 100, the 5 floorboards (115L, 115R) of the vehicle 100 are shown. The one or more front wheels 110 and the vehicle suspension system 108 are disposed within the front wheel well 112. The front wheel well 112 is configured for ensuring the rotatability of the front wheel 110 and the suspension system 108 about an axis of the head pipe 101. The one or more energy storage devices (106L, 106R) are also visible from 10 the top view of the vehicle 100. The one or more thermal runaway valves (111L, 111R) are disposed on the one or more energy storage devices (106L, 106R). It can be seen in the present exemplary illustration that the one or more thermal runaway valves are disposed at the frontmost topmost portion of the respective one or more energy storage devices (106L, 106R). Also, the one or more energy storage devices 15 (106L, 106R) are arranged lengthwise along a vehicle 100 front rear direction, and they are arranged substantially parallelly to each other. As per an embodiment of the present invention, the width of a casing of the energy storage device 106 is configured so that the one or more energy storge devices (106L, 106R) are disposed within a vehicle 100 widthwise boundary defined by the inner edges on the 20 floorboards (115L, 115R). This boundary is also defined by the battery holder 104 (shown in figure 3).The rearward portion of the one or more energy storage devices 106 are configured to receive one or more electrical and electronic connectors and one or more battery management systems. The electrical energy stored in the one or more energy storage devices 106 are used to power one or more electric machines 25 and electronic components of the vehicle 100. As per an embodiment of the present subject matter, the one or more electric machines and electronic components of the vehicle 100 are disposed rearwards of the one or more energy storage devices (106L, 106R). As per the present subject matter, a panel 112 facing the front wheel well has an opening 113 to allow the gases and liquids to escape frontwards, away 30
13
from the user of the vehicle 100. As per another embodiment of the present subject matter, the opening 113 is partially covered by an air duct (not shown). [00035] Figure 5 is an exemplary illustration of the vehicle 100, and the disposition of the one or more thermal runaway valve(s) (111L, 111R) on the one or more energy storage devices 106 with respect to the front wheel 110 of the vehicle 100, 5 and the opening 113 in the panel 112 facing the front wheel well of the vehicle 100. The panel 112 facing the front wheel well is a crucial aerodynamic part of the vehicle 100, which is configured for either directing atmospheric air around the vehicle 100 or into the one or more air channels created by the vehicle’s parts. As per the present subject matter, the panel 112 facing the front wheel well has an 10 opening 113 which is configured directly in line with the one or more thermal runaway valves (111L, 111R), disposed on the one or more energy storage devices (106L, 106R). In the event one or more of the thermal runaway valves (111L, 111R) disintegrate and the gases and liquids escape, they would be directed outside the vehicle 100 through the opening 113 away from the other critical parts of the vehicle 15 100, and away from the user of the vehicle 100, thus reducing damage to both user and the vehicle 100. As per the present subject matter, the opening 113 is between the first imaginary plane (A-A’) and the second imaginary plane (B-B’) as shown in figure 4(b). Further, as per an embodiment of the present subject matter, the opening 113 is disposed above the topmost portion of the front wheel 110, and a 20 cover, the cover is provided to cover a top portion of the front wheel 110 and therefore, there will be no obstacles to the escaping liquids and gases.
[00036] Figure 6 is an exemplary illustration of an energy storage device 106, and the disposition of the thermal runaway valve 111 on the energy storage device 106. In the present illustration, only the outer casing of the energy storage device 106 is 25 being shown. The outer casing can be classified into side cover 106A, bottom cover 106B, and top cover 106C. According to the present embodiment, the thermal runaway valve 111 is disposed on the top cover 106C of the outer casing of the energy storage device 106. According to the present subject matter, the thermal runaway valve 111 is disposed in a frontward orientation of the energy storage 30 device 106 in the vehicle 100 front rear direction. The rearward side of the energy
14
storage device 106 is configured for disposing one or more electrical and electronic connections. Further, as per an embodiment of the present embodiment, the outer casing of the energy storage device 106 is configured with one or more heat dissipating means.

As per the present subject matter, the front panel has an opening 113 configured in line with the one or more thermal runaway valves 111 disposed on the one or more energy storage devices 106. According to the embodiment of the present subject matter shown in the illustration in figure 7, the opening 113 is covered by an inlet covering. This 10 covering is provided for preventing mud, water, and any large particles from entering through the opening and damaging the energy storage devices 106 and the thermal runaway valves 111. The front wheel well 112 as a whole is configured so that the front wheel 110 and the vehicle suspension system 108 have rotatability within the region defined by the front wheel well 112. 15
