DETAILED DESCRIPTION
[00015] The energy storage device industry in continually expanding to meet the increasing energy needs of the portable equipment, transportation and communication markets.
[00016] 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 cost of manufacturing, which includes the 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 have multiple applications.
[00017] 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.
[00018] In recent years, hybrid vehicles and electric vehicles have become quite popular 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
[00019] 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.
[00020] Thus, electric vehicles have gained popularity in recent years as the potential replacement for internal combustion vehicles, since they promise zero emission from electric drive system, and a break away from oil dependency. 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 heavy, bulky, and have short cycle life, short calendar life, and low turn around efficiency. Hence, a pure electric vehicle entails a problem in that its own weight increases and due to packaging constraints it is difficult to mount one or more energy storage devices as an additional rechargeable back-up power source in the limited spaces of the vehicle which may involve further structural challenges for installing the one or more additional energy storage devices thereon.
[00021] In order to overcome problems associated with the conventional energy storage devices including rechargeable energy storage devices like the lead-acid energy storage devices for the vehicle, a lithium ion energy storage device provides an ideal system for high energy-density applications, improved rate capability, and safety. The rechargeable energy storage devices can be repeatedly recharged and reused, thus are economical in the long run, environmentally friendly as compared to disposable energy storage devices.
[00022] Further, the rechargeable energy storage devices - lithium-ion energy storage devices exhibit one or more beneficial characteristics which make it preferred on the vehicle. First, for safety reasons, the lithium ion energy storage device is constructed of all solid components while still being flexible and compact. Secondly, the energy storage device, including the lithium ion energy storage device, exhibits 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. Thirdly, the energy storage device as the lithium ion energy storage device is readily manufacturable in a manner that it is both reliable and cost-efficient. Finally, the energy storage device including the lithium ion energy storage device is able to maintain a necessary minimum level of conductivity at sub-ambient temperatures.
[00023] In a conventional structure for an energy storage device, the one or more energy storage cells including lithium ion energy storage cells which 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 technologies. The adaptation of different joining technologies greatly influences the primary characteristics of pack of energy storage devices, in terms of performance, capacity and lifetime. Selection of suitable joining technology, therefore, involves several considerations regarding electrical and mechanical properties and an assessment of production and operational conditions.
[00024] Generally, one or more interconnecting structures are adapted for electrically interconnecting at least one array of the one or more energy storage cells being disposed in the at least one energy storage device holder. Particularly, each of the one or more interconnecting structures and at least one of the one or more energy storage cells are made of dissimilar materials. Hence the one or more interconnecting plates including metal plates having high thermal and electrical conductivity are electrically connected to at least one terminal of each of the one or more energy storage cells through a spot welding method to form at least one contact point.
[00025] Furthermore, each of the one or more interconnecting structures are joined or connected with a battery management system for regulating/monitoring the performance of the energy storage cells. Each of the one or more interconnecting structures is connected to the battery management system through different connection means like wire having different cross sections and with attachment means like, multiple fasteners. This conventional connecting method for connecting each of the one or more interconnector structures with battery management system is tedious, as each array of energy storage cells is having wires to be connected to the corresponding part of battery management system. Further, the use of multiple fasteners creates stress on the connecting portion of the battery management system and the each of the one or more interconnecting structures, which may lead to breakage of the components. Furthermore, both terminals of energy storage cells have to be connected to the battery management system. So, this increases the time of assembly and also, in some cases may lead to wrong assembly. Thus, there is a need for a solution of connecting each of the one or more interconnector structures with the battery management system which can overcome the above mentioned problem.
[00026] In known art, one or more interconnector structures termed here as a conductive bridge comprises bridge connectors. The bridge connector is separately fabricated to be electrically connected to battery management system by soldering or insertion of the wires. This solution as proposed in the known art leads to same problems as discussed earlier like as increased assembly and disassembly time for connecting the each of one or more interconnecting structures with the battery management system.
[00027] Hence, there exists a challenge of designing an energy storage device pack, which can quickly and in a simple manner, connect one or more interconnecting structures and battery management system, thereby, overcoming all problems of known art.
[00028] Therefore, there is a need to have an improved an energy storage device pack which overcomes all of the above problems and other problems of known art.
