Li-Ion cell

Overheating is one of the main reasons that accelerates the rate of battery discharge in electric vehicles and leads to the deterioration of its performance over time. Rapid charging of the battery is not beneficial for its longevity, as high currents increase the temperature and can irreversibly damage the internal structure of the battery. At optimal temperatures, the availability of discharge power, charge reception during regenerative braking and battery health are at the best level.

In modern autonomous electric power supply systems, in particular, for electric vehicles (EV), rechargeable batteries (B) are often used as energy sources and supercapacitor (SC) modules are often used as power sources. To ensure the necessary level of on-board voltage, these devices consist of a large number of low-voltage cells, the work of which is accompanied by complex electronic energy management systems (EMS).
