What is the charging capacity of a parallel battery pack?

For charging time, the charging capacity of the parallel battery pack is 20.50 Ah in 1964 s, which is equivalent to charging the battery pack at a constant current of 37.58 A (i.e., 1.25C). In addition, the effect is significantly better than the fast charging of CC-CV of 1C.

How does a parallel battery pack work?

In other words, for a parallel battery pack, the initial input total current is the current of a cell multiplied by the number of branches. At the same time, as the charging process goes on, the overpotential will decrease, requiring subsequent control.

Why is the current distribution of a parallel battery pack difficult?

Compared to series battery packs, the current distribution of each branch for parallel battery pack is very inconsistent and complicated because of the resistances caused by the wire and welding ( Hosseinzadeh et al., 2021; Wu et al., 2021 ).

Do series and parallel branch resistances affect EV charging duration and efficiency?

The effects of series and parallel branch resistances on charging duration and efficiency are also explored at the model level. 3. Finally, the advanced charging strategy is applied to a specific EV, and compared with its former charging profile and other vehicles.

Do parallel and serial branch resistances affect pack charging performance?

Impacts on pack parallel and serial branch resistances on pack charging performance are also investigated. For onboard application, simulation is extended to a real-world 58.8 kWh EV comprised of 276 cells, reducing the time to replenish 200 km of range to merely 12.5 mins.

What is the difference between a battery pack and a module?

The current through each module is identical, which ensures uniform electric capacity throughput across the series configuration. The battery pack capacity is governed by the module with the minimum available discharge capacity (Q min D) and the module with minimal available charge capacity (Q min C) .
