BACKGROUND

Batteries are a useful source of stored energy that is incorporated into devices, systems, vehicles etc., where the batteries are formed by combining a plurality of cells. The batteries are responsible for operating the devices, systems, vehicles, etc. Thus, nowadays, rechargeable batteries are preferred by users. There are different types of rechargeable batteries available, for example, lead-acid batteries and lithium-ion batteries. However, the lead-acid batteries have limitations such as short life span, heavy configuration, etc. In view of the same, the lithium-ion batteries have emerged as a preferred solution. There are several types of lithium-ion batteries, for example, Nickel Manganese Cobalt (NMC) batteries, Lithium Iron Phosphate (LiFePO4) batteries, etc.

Conventionally, the batteries with increased efficiency are preferred to operate the vehicles. Thus, in view of the same, the batteries, with a cylindrical profile, are preferred to operate the vehicles. The cylindrical batteries are compatible for high-performance applications. However, the main challenge lies in packaging of the cylindrical batteries such that the cylindrical batteries can be used in the vehicles. In view of the same, there is a requirement to provide a battery pack to hold the cylindrical batteries in such a manner that the batteries can be used in the vehicles.

Hence, there is a requirement to provide the battery pack compatible for holding the cylindrical batteries in such a manner that the cylindrical batteries can be used in the vehicles.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

For the sake of clarity, the first digit of a reference numeral of each component of the present disclosure is indicative of the Figure number, in which the corresponding component is shown. For example, reference numerals starting with digit “1” are shown at least in Figure 1. Similarly, reference numerals starting with digit “2” are shown at least in Figure 2.

An Electric Vehicle (EV) or a battery powered vehicle including, and not limited to two-wheelers such as scooters, mopeds, motorbikes/motorcycles; three-wheelers such as auto-rickshaws, four-wheelers such as cars and other Light Commercial Vehicles (LCVs) and Heavy Commercial Vehicles (HCVs) primarily work on the principle of driving an electric motor using the power from the batteries provided in the EV. Furthermore, the electric vehicle may have at least one wheel which is electrically powered to traverse such a vehicle. The term ‘wheel’ may be referred to any ground-engaging member which allows traversal of the electric vehicle over a path. The types of EVs include Battery Electric Vehicle (BEV), Hybrid Electric Vehicle (HEV) and Range Extended Electric Vehicle. However, the subsequent paragraphs pertain to the different elements of a Battery Electric Vehicle (BEV).

Referring to Figure 1A, in construction, an EV 10 typically comprises a battery enclosed within a battery casing or a battery pack 100 and includes a Battery Management System (BMS), an on-board charger 14, a Motor Controller Unit (MCU), an electric motor 16 and an electric transmission system 18. The primary function of the above-mentioned elements is detailed in the subsequent paragraphs: The battery of an EV 10 (also known as Electric Vehicle Battery (EVB) or traction battery) is re-chargeable in nature and is the primary source of energy required for the operation of the EV, wherein the battery is typically charged using the electric current taken from the grid through a charging infrastructure 20. The battery may be charged using Alternating Current (AC) or Direct Current (DC), wherein in case of AC input, the on-board charger 14 converts the AC signal to DC signal after which the DC signal is transmitted to the battery via the BMS. However, in case of DC charging, the on-board charger 14 is bypassed, and the current is transmitted directly to the battery via the BMS.

The battery is made up of a plurality of cells which are grouped into a plurality of modules in a manner in which the temperature difference between the cells does not exceed 5 degrees Celsius. The terms “battery”, “cell”, and “battery cell” may be used interchangeably and may refer to any of a variety of different rechargeable cell compositions and configurations including, but not limited to, lithium-ion (e.g., lithium iron phosphate, lithium cobalt oxide, other lithium metal oxides, etc.), lithium-ion polymer, nickel metal hydride, nickel cadmium, nickel hydrogen, nickel-zinc, silver zinc, or other battery type/configuration. The term “battery pack” as used herein may be referred to multiple individual batteries enclosed within a single structure or multi-piece structure. The individual batteries may be electrically interconnected to achieve a desired voltage and capacity for a desired application. The Battery Management System (BMS) is an electronic system whose primary function is to ensure that the battery is operating safely and efficiently. The BMS continuously monitors different parameters of the battery such as temperature, voltage, current and so on, and communicates these parameters to the Electronic Control Unit (ECU) and the Motor Controller Unit (MCU) in the EV using a plurality of protocols including and not limited to Controller Area Network (CAN) bus protocol which facilitates the communication between the ECU/MCU and other peripheral elements of the EV 10 without the requirement of a host computer.

The MCU primarily controls/regulates the operation of the electric motor 16 based on the signal transmitted from the vehicle battery, wherein the primary functions of the MCU include starting of the electric motor 16, stopping the electric motor 16, controlling the speed of the electric motor 16, enabling the vehicle to move in a reverse direction and protect the electric motor 16 from premature wear and tear. The primary function of the electric motor 16 is to convert electrical energy into mechanical energy, wherein the converted mechanical energy is subsequently transferred to the transmission system of the EV to facilitate movement of the EV. Additionally, the electric motor 16 also acts as a generator during regenerative braking (i.e., kinetic energy generated during vehicle braking/deceleration is converted into potential energy and stored in the battery of the EV). The types of motors generally employed in EVs include, but are not limited to DC series motor, Brushless DC motor (also known as BLDC motors), Permanent Magnet Synchronous Motor (PMSM), Three Phase AC Induction Motors and Switched Reluctance Motors (SRM).

The transmission system 18 of the EV 10 facilitates the transfer of the generated mechanical energy by the electric motor 16 to the wheels 22a,22b of the EV. Generally, the transmission systems 18 used in EVs include single speed transmission system and multi-speed (i.e., two-speed) transmission system, wherein the single speed transmission system comprises a single gear pair whereby the EV is maintained at a constant speed. However, the multi-speed/two-speed transmission system comprises a compound planetary gear system with a double pinion planetary gear set and a single pinion planetary gear set thereby resulting in two different gear ratios which facilitates higher torque and vehicle speed.

In one embodiment, all data pertaining to the EV 10 and/or charging infrastructure 20 are collected and processed using a remote server (known as cloud) 24, wherein the processed data is indicated to the rider/driver of the EV 10 through a display unit present in the dashboard 26 of the EV 10. In an embodiment, the display unit may be an interactive display unit. In another embodiment, the display unit may be a non-interactive display unit.
