BACKGROUND
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Electric vehicles (EVs) have become an increasingly popular mode of transportation in recent years due to their lower environmental impact and cost savings over traditional internal combustion engine (ICE) vehicles. However, contemporary electric vehicles have a fixed maximum range, which limits their utilization and is impacting the faster adoption of EVs. This range limitation often requires drivers to purchase a vehicle with a much higher cost to access extra range a few times each month, or rely on an ICE vehicle for longer trips.
[0004] As the demand for electric vehicles grows, the need for longer range and more efficient batteries becomes increasingly important. In order to meet this demand, there has been significant research and development in the field of battery technology, resulting in the creation of more efficient and powerful batteries. However, despite these advancements, there is still a need for further improvement in the technology to provide electric vehicles with a range that is comparable to ICE vehicles.
[0005] This patent application seeks to address the limitations of contemporary electric vehicles by providing a solution that increases the range and utilization of electric vehicles. The proposed technology aims to enhance the battery performance of electric vehicles, allowing them to travel longer distances on a single charge. This will not only provide greater convenience for drivers, but also make electric vehicles a more attractive and viable option for a wider range of consumers.
[0006] By providing a solution that addresses the range limitation of contemporary electric vehicles, this patent application aims to promote the adoption of electric vehicles and contribute to the reduction of greenhouse gas emissions from transportation.
[0007] There is therefore a need in the art to provide device and method for demand-based switching standalone batteries that seeks to overcome or at least ameliorate one or more of the above-mentioned problems and other limitations of the existing solutions and utilize techniques, which are robust, accurate, fast, efficient, cost-effective and simple.
