Therefore, it is necessary to take equalization measures to ensure the safe and efficient use of the battery system. At present, the equalization methods are mainly divided into two kinds: passive equalization and active equalization [10, 11]. The passive equalization mainly uses the parallel resistor to consume excess energy. ...
Based on the above analysis, this paper proposes an active equalization method for series-parallel battery pack based on an inductor. The main contributions are described below. The energy storage device responsible for energy transfer requires only one inductor and the topology is simple and low cost.
The battery equalization is divided into two categories according to the different energy conversion: passive equalization and active equalization , , . Passive equalization employs two commonly used topologies: the fixed shunt equalizer and the switching shunt resistor equalizer.
Studies on the equalization of parallel battery pack have also been conducted , , . The literatures , achieve parallel equalization by adding a DC/DC converter for each parallel module, which is not conducive to the size and cost reduction of the equalization system .
A suitably sized active equalization is designed within the pack as the second-level equalization for achieving intra-group battery equalization. The diagram of the equalization architecture is divided into four parts: dynamic data collection, data processing, equalization strategy, and equalization topology, as shown in Fig. 1.
Based on this, capacitors and multiple cells are connected in parallel to rapidly equalize the overall energy level of the battery pack. Subsequently, precise adjustments are made through the equalization process using inductors. The topology proposed in this work is an improvement of the traditional inductive equalization.
