Part Three DC System Configuration Plan 1. GZDW30 solution, single battery pack, no voltage reduction device, DC bus segmentation, the combined bus and control bus of each DC bus section are shared; 2. GZDW31 solution, single battery pack, no voltage reduction device, DC bus not segmented, common bus and control bus; 3. GZDW32 solution, single battery pack, voltage reduction device, DC bus segmentation; 4. GZDW33 solution, single battery pack, with voltage reduction device, and the DC bus is not segmented; 5.
GZDW34 solution, single battery pack, with voltage reduction device, DC bus segmentation, switching power supply module is divided into two groups, one group is connected to the charging bus, The other group is connected to the control bus; 6. GZDW35 solution, single battery pack, with voltage reduction device, the DC bus is not segmented, the switching power supply module is divided into two groups, one group is connected to the charging bus On the other hand, the other group is connected to the control bus; 7. GZDW40 solution, dual battery packs, two sets of switching power supply modules, dual charging buses, no voltage reduction device, and DC bus segmentation; 8.
GZDW42 solution, dual battery packs, two sets of switching power supply modules, dual charging buses, voltage reduction device, and DC bus segmentation. —- 13 —-
