It is essential to understand the core components and working principles to appreciate the complexities of the system.

Lithium-ion batteries, the backbone of most SE Power EV battery packs, are composed of several key parts: the anode (negative electrode), cathode (positive electrode), electrolyte (a liquid or gel that facilitates ion movement), and a separator (to prevent short circuits). During charging, lithium ions move from the cathode to the anode, storing energy. When you drive, the ions flow back to the cathode, releasing the stored energy to power your vehicle. These batteries are known for their high energy density, which means they can store a lot of energy in a relatively small space. However, they also have a finite lifespan, with their capacity gradually decreasing over time due to repeated charge and discharge cycles. This degradation is a natural process, and understanding it is key to maintaining your SE Power EV battery.

Battery management systems (BMS) play a critical role, constantly monitoring the battery's health. The BMS ensures that individual cells are charged and discharged evenly, preventing overcharging, over-discharging, and overheating. Overheating can be a significant issue, so the BMS often includes thermal management systems to keep the battery operating within safe temperature ranges. These systems can include liquid cooling or air cooling, depending on the battery design.
