DESC:SWAPPABLE POWER PACK FOR ELECTRIC VEHICLE
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims priority from Indian Provisional Patent Application No. 202321006471 filed on 01/02/2023, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
The present disclosure generally relates to swappable power packs. The present disclosure particularly relates to a swappable power pack for an electric vehicle.
BACKGROUND
Recently, there has been a rapid development in electric vehicles because of their ability to resolve pollution-related problems and serve as a clean mode of transportation. Generally, electric vehicles include a battery pack, power pack, and/or combination of electric cells for storing electricity required for the propulsion of the vehicles. The electrical power stored in the battery pack of the electric vehicle is supplied to the traction motor for moving the electric vehicle. Once the electrical power stored in the battery pack of the electric vehicle is depleted, the battery pack is required to be charged from a power source or by replacing the depleted battery pack with a fully charged battery pack.
The replaceable battery packs are also known as swappable battery packs and resolve the problems of charger availability and range anxiety associated with fixed battery packs. Moreover, the swappable battery packs may also solve the problem high initial cost of ownership of the electric vehicles. Since the battery is the most expensive component of the electric vehicle, the cost associated with the ownership of the battery pack may be eliminated by getting a swappable battery as a service.
However, the swappable battery packs also require infrastructure in terms of battery swapping stations. The battery swapping stations convert the electrical energy received from the grid to charge the swappable battery packs. Furthermore, the electric vehicle itself requires a power converter to convert the electrical energy stored in the battery pack for driving the traction motor. Moreover, if the swappable battery pack is required to be charged with a charger, while being in the electric vehicle, the charger would also require a suitable power converter to convert the electrical energy received from the power source (grid) to charge the swappable battery pack. Moreover, the domestic uninterrupted power supply systems have also recently started being used for charging the swappable battery packs, while delivering power backup as and when required. However, the domestic uninterrupted power supply systems would also require a power converter to convert the electrical energy received from the domestic AC supply to charge the swappable battery packs and convert the electrical energy stored in the swappable battery pack to provide power backup for the domestic load. Such arrangements are costly as multiple sets of power converters are required to either charge or utilize the charged swappable battery pack. Moreover, a lot of electronic components are redundant on the charging equipment side when the swappable battery is being utilized for powering up electric equipment (either mobility or fixed). Similarly, a lot of electronic components are redundant on the discharging equipment side (mobility or fixed) when the swappable battery is being charged. Such redundancy increases the overall cost of the swappable battery ecosystem and hinders the use of swappable battery packs as clean energy storage solutions for mobility and fixed applications.
Therefore, there exists a need for an improved swappable battery pack and overcome one or more problems associated as set forth above.
