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.
In an electric vehicle (EV), the battery configuration refers to the arrangement of individual battery cells within the battery pack. This configuration affects the voltage, capacity, power output, and overall vehicle performance. The most common configuration for EV batteries is a series-parallel hybrid.
In order to increase the current capability the battery capacity, more strings have to be connected in parallel. For example, 3 strings connected in parallel will triple the capacity and current capability of the battery pack.
Batteries have two or more cells. A cell is a device that produces electricity at a fixed voltage with limited current capacity. According to this definition, the small batteries sold to consumers are not batteries but cells. The different cell types have different voltages and current capacities and support different loads (see Figure 1).
The number of battery cells connected in series N cs [-] in a string is calculated by dividing the nominal battery pack voltage U bp [V] to the voltage of each battery cell U bc [V]. The number of strings must be an integer. Therefore, the result of the calculation is rounded to the higher integer.
The total voltage given out by these cells will however remain at 24 volts. To harness the benefits of both series and parallel connections, most battery configurations adopt both methods to increase output voltage of a battery at the same time the capacity of batteries.
Battery configurations (series and parallel) and their protections
The battery configuration is S4 (four in series), and a fuse is connected to the positive side of the battery to shut off the battery when the current exceeds the limits. There is BMS Monitoring every cell voltage for balancing and fault detection. The current sensing unit will sense the charge and discharge the current it sends to BMS. If any ...
