Abstract EN
With the rapid development of energy internet and new energy-related industries, lithium-ion batteries are widely used in various fields due to their superior energy storage characteristics.
To reduce the influence of the inconsistency of the individual cells in the battery pack, a switch array DC equalization circuit together with an acceleration information Gauss-Seidel (DAIGS) method is proposed.
The aging factor is added in the system state matrix considering the battery time effect.
In this method, the energy transfer path can be optimized by updating the switch control matrix in each iteration.
Hence, it can avoid the repeated charging and discharging of the battery and also reduce energy loss in rapid equalization.
A four-cell battery string equalization model simulation was built in the PSIM and the experiment was also carried out to prove the feasibility of the proposed method.
It was verified that the DAIGS had better performance under the same precision or number of iterations.
