Abstract:

The inconsistency will gradually appear between monomer batteries of aircraft battery, which will reduce performance and service life of the battery, and even lead to security incidents. This paper presents a structure of active balancing for aircraft battery equalization system. A bidirectional energy transfer balanced topology is proposed based on Cúk converter, and a balancing control strategy for both top and bottom balancing is designed. An energy equalization system for aircraft Ni-Cd battery is developed. Experiments are conducted to analyze the energy equalization of Ni-Cd battery series battery. Experimental results show that the proposed energy equalizer has the characteristics of high speed, random choice of balanced single battery, and bi-directional transformation of energy. The equalizer can reduce the inconsistencies in the battery monomer, and improve the capacity utilization ratio and service life of the battery pack.

Key words: aircraft battery, series connected batteries, battery equalization, active balancing, balancing control strategy
