6 FAQs about [The latest technical specifications for battery pack series connection]

Is there a connection between battery pack and series cells?

What is a structural battery pack?

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.

What is the relationship between battery pack capacity and series cell capacity?

Fig. 8 shows the relationship between the battery pack capacity and the series cell capacity, taking a battery pack with three cells connected in series as an example. Battery pack capacity is defined as the maximum capacity of the battery pack that can be charged from a discharged state to a fully charged state.

What are the operating conditions of a battery pack?

The operating conditions of battery pack are different from those of single cell, with the former typically utilizing a multi-stage constant current mode rather than the constant voltage charging mode commonly used for single cells.
