Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0017] Such as figure 1 The high-voltage power distribution device of the hybrid electric bus shown. The charging circuit part includes: ISG motor 1, ISG motor controller 2, supercapacitor 8; the discharging circuit part includes: supercapacitor 8, drive motor controller 6, and drive motor 5. The negative terminals of ISG motor controller 2 and drive motor controller 6 are connected to the negative terminals of supercapacitor 8, and a switching circuit for charging and discharging is also provided. The positive end of the device 6 is short-circuited, and the other end is connected to the positive end of the supercapacitor 8; the switching circuit is composed of two parallel branches, one parallel branch is composed of a group of contacts 3 of the first contactor and the first resistor 4, Another parallel branch is formed by a set of contacts 7 of the second...
