GZDW series selection program is generally divided into eight categories:

1. GZDW30: single bus segmented, single battery, single voltage output of charging module to mother power supply, control mother and moving mother united, no pressure reducing device

2. GZDW31: single busbar, single battery, single voltage output of the charging module to the mother power supply, control mother and dynamic mother, and no pressure-reducing device

3, GZDW32: single bus segment, single battery, single voltage output of the charging module to the mother power, control mother and mother separated, there is a pressure reducing device

4. GZDW33: single busbar, single battery, single voltage output of charging module to mother power supply, control mother and mother mover separately, and pressure-relief device

5, GZDW34: single bus segment, single battery, charging module is divided into two sets of voltage supply to mother and control mother, control mother and mother separately, there is a pressure reducing device

6, GZDW35: single bus, single battery, charging module is divided into two sets of voltage respectively to mother and control mother supply, control mother and mother separated, there is a pressure reducing device

7, GZDW40: single bus segmented, dual battery, dual charging module single voltage output to the mother power supply, control mother and moving mother unity, no pressure reducing device

8. GZDW42: single bus-bar segmented, dual-battery, dual-group charging module single voltage output to the mother power supply, control mother and moving mother
