The complexity (and cost) of the charging system is primarily dependent on the type of battery and the recharge time.

In this type of arrangement, we refer to each pair of series connected batteries as a "string". Batteries A and C are in series. Batteries B and D are in series. The string A and C is in parallel with the string B and D. Notice that the total battery pack voltage is 24 volts and that the total battery pack capacity is 40 amp-hours.
A structural battery pack is designed to become a structural component of the EV. This approach can reduce the EV’s weight by removing duplicate structures between the pack and the vehicle structure, as the battery pack becomes part of the vehicle structure. This design can improve the EV’s overall performance and efficiency.
To calculate the gross battery pack size, multiply the total parallel capacity in ampere-hours (Ah) by the battery pack’s nominal voltage in volts (V). The result is in watt-hours (Wh). The diagram below shows the configuration of a battery module from the Audi Q8 e-tron 55.

The safety circuitry includes a Li-ion protector that controls back-to-back FET switches. These switches can be
The constant voltage portion of the charge cycle begins when the battery voltage sensed by the charger reaches 4.20V. At this point, the charger reduces the charging current as required to hold the sensed voltage constant at 4.2V, resulting in a current waveform that is shaped like an exponential decay.
