Innovations in battery design aim to increase energy density, allowing more energy to be stored in smaller, lighter packs. This not only improves the range and efficiency of EVs but also enhances the vehicle's overall usability and comfort.
The hardware comprises five fundamental components: the battery pack, power electronic converters, charging system, battery management system (BMS) and traction motor. The energy source powering the vehicle and the arrangement of these various components brings about the various configurations of the EV .
The Battery Electric Vehicles (BEV) consist of a battery pack, propulsion motor, and a bidirectional power electronic converter, as shown in Figure 4. The architecture of the battery electric vehicles. The BEVs are powered exclusively by electrical power from a battery pack . The most widely used battery type is the Lithium-Ion (Li-ion).
The powertrain of any Electric Vehicle architecture comprises a combination of software, sensors, and hardware. The general configuration of an EV is shown in Figure 3. The hardware comprises five fundamental components: the battery pack, power electronic converters, charging system, battery management system (BMS) and traction motor.
Based on practical requirements such as cost, environmental protection, service cycle, and performance, batteries should possess at least five basic characteristics: low cost, low hazard potential, high energy density, long cycle life, and high-power density.
The battery pack is the most vital and most expensive component of an EV. It is approximately 25%–50% of the acquisition cost of the electric vehicle . Therefore, carefully selecting the battery technology for the EV is paramount. It translates to the cost, weight, capacity, efficiency, durability, and overall performance.
