Description:TECHNICAL FIELD
[0001] The present subject matter relates to an energy storage device pack. More particularly, the present subject matter relates to connecting members provided within the energy storage device. The present subject matter is a patent of addition for application having application number ‘201841042121’.
BACKGROUND
[0002] The energy storage device industry in continually expanding to meet the increasing energy needs of the portable equipment, transportation and communication markets. Considering the recent trend, the arena of technology pertaining to transportation has undergone a tremendous transformation over the years. At present major focus is on energy efficiency and reduction in cost of manufacturing. Cost of manufacturing includes cost of materials, assembly cost, cost of inventory handling etc. Simultaneously, there has also been need in the industry to provide stronger, lighter and economically advantageous vehicles that consume less power. Electric power storage device driven vehicles happen to be eco-friendly, in line with the Go Green initiative of various organizations. These vehicles may be two, three or four wheelers depending upon the requirement of the consumer and intended use.
[0003] In automobile vehicle industry, electric vehicles are introduced to control or reduce air pollution caused due to IC engine powered vehicles. Currently, the electric vehicles are classified into two groups, namely pure electric and extended electric vehicles (also known as hybrid vehicles). The hybrid vehicles have a primary electric drive with associated energy storage device and an internal combustion engine coupled to an electric motor/generator.
[0004] In recent years, hybrid vehicles and electric vehicles have attained popularity due to high oil prices and the environmental impact of pure gasoline fuel consumption vehicles. In particular, the hybrid vehicle has become an intermediate choice for those consumers wishing to reduce fuel consumption while at the same time increase their allowable travel distance.
[0005] Generally, existing hybrid vehicles are configured to be powered either by an internal combustion engine or electric motor or both; by replacing normal engine powered vehicles. For example, driving on terrain or for long distances, an internal combustion engine can be used and for shorter distances electric propulsion system can be used. However, incorporation of both internal combustion engine and electric motor assembly in the hybrid two-wheeled vehicle makes the system bulky and more complex.
[0006] Considering the challenges associated with the hybrid and internal combustion engine-based vehicles, electric vehicles have gained popularity in recent years as a potential replacement for the internal combustion-based vehicles and hybrid vehicles. Hence, a focus of the electric vehicle industry in energy storage device research is directed to rechargeable energy storage devices, such as sealed, starved electrolyte, lead/acid energy storage devices which are commonly used as power sources in vehicles and the like. However, lead-acid energy storage devices are usually heavy, bulky, and have short cycle life, short calendar life, and low turn around efficiency. Owing to heaviness and bulkiness of the lead-acid energy storage devices, it becomes a challenge to mount multiple energy storage devices as additional rechargeable back-up power sources on a single vehicle, especially small vehicles with limited space, such as two-wheelers.

DETAILED DESCRIPTION
[00016] In order to overcome problems associated with the conventional energy storage devices including lead-acid energy storage devices, a lithium-ion energy storage device provides an ideal system for high energy-density applications with safety. The rechargeable energy storage devices can be repeatedly recharged and reused, making them an economical and environment friendly energy source in the long run.
[00017] Further, the lithium-ion energy storage devices exhibit at least one beneficial characteristics making them preferred energy source for vehicles. Some of the beneficial characteristics include compactness; exhibition of conductivity characteristics similar to primary energy storage devices, with liquid electrolytes, i.e., deliver high power and energy density with low rates of self-discharge; and easy, reliable and cost-effective manufacturability.
[00018] In a conventional structure for a lithium-ion energy storage device, the at least one energy storage cells including lithium-ion energy storage cells are disposed in at least one cell holder structure in series and parallel combinations. The interconnecting structures of the energy storage cells create an electrical and mechanical connection, which can be accomplished by means of different joining techniques. The adaptation of different joining techniques greatly influences the primary characteristics of pack of energy storage devices, in terms of performance, capacity and lifetime. Selection of suitable joining technique, therefore, involves several considerations regarding electrical and mechanical properties and an assessment of production and operational conditions.
[00019] Generally, at least one interconnecting structures are adapted for electrically interconnecting at least one array of the at least one energy storage cells being disposed in the at least one energy storage device holder. Particularly, each of the at least one interconnecting structures and at least one of the at least one energy storage cells are made of dissimilar materials. Hence the at least one interconnecting plates including metal plates having high thermal and electrical conductivity are electrically connected to at least one terminal of each of the at least one energy storage cells through a spot-welding method to form at least one contact point.
[00020] Furthermore, each of the at least one interconnecting structures are joined or connected with a battery management system for regulating/monitoring the performance of the energy storage cells. Each of the at least one interconnecting structures is connected to the battery management system through different connection means like via cables having different cross sections and with attachment means like, multiple fasteners. This conventional connecting method for connecting each of the at least one interconnector structures with the battery management system is tedious, as each array of energy storage cells are usually having cables to be connected to the corresponding part of battery management system. Further, the use of multiple fasteners localized stress on the connecting portion of the battery management system and each of the at least one interconnecting structures. Such localized stress may lead to localized cracks and at least one breakage of the connecting portions and adjoining components. In worst case scenarios such localized cracks may lead to short circuits, thereby compromising the safety of the battery.
[00021] Furthermore, since both terminals of the energy storage cells requires to be connected to the battery management system. Thereby use of multiple separate fasteners increases the time of assembly. In some cases, where different types of fasteners are used, separate assembly of each fastener may lead to wrong assembly. Thus, there is a need for a solution of connecting each of the at least one interconnector structures with the battery management system which can overcome the above-mentioned problems.
[00022] In known art, at least one interconnector structures also termed as conductive bridges comprises of multiple bridge connectors. Each of the bridge connector is separately fabricated to be electrically connected to the battery management system by soldering or inserting wires. This solution as proposed in the known art leads to same problems as discussed above, such as increased assembly and disassembly time for connecting each of at least one interconnecting structures with the battery management system.
[00023] Hence, there exists a challenge of designing an energy storage device pack, which can enable easy assembly and disassembly of at least one interconnecting structures and battery management system, thereby, overcoming all problems of known art.
[00024] Therefore, there is a need to have an improved energy storage device pack which is capable of overcoming all of the above problems and other problems of the known art.
[00025] The present subject matter discloses an energy storage device pack having at least one connecting means to ensure the connection between the at least one interconnector structures and the battery management system while ensuring safety of the vehicle.
