Embodiment Construction

[0014] See attached picture.

[0015] figure 1 is a schematic diagram of the electrical architecture. It can be seen from the figure that the power control unit can complete the following working modes.

[0016] 1. The bodywork battery supplies power to the bodywork load, and the chassis battery supplies power to the chassis load;

[0017] When the vehicle is running and working normally, relays ZJ1, ZJ2, ZJ3 and ZJ4 are closed, relays ZJ5 and ZJ6 are disconnected, the bodywork battery system supplies power to the bodywork load, and the chassis battery system supplies power to the chassis.

[0018] 2. The bodywork battery supplies power to the chassis load, and the chassis battery supplies power to the bodywork load;

[0019] When the vehicle bodywork battery system is out of power and the bodywork still needs to work, close ZJ1, ZJ2, ZJ5, ZJ6 relays to realize the chassis battery system supplying power to the bodywork load. When the vehicle chassis battery system is dead a...

Abstract

The invention discloses a multi-power battery system structure of a pure electric special vehicle. The multi-power battery system structure comprises a chassis battery system, an upper part battery system, a chassis, an upper part, a power control unit, a chassis electricity load and an upper part electricity load. When the vehicle works normally, the chassis battery system supplies power to the chassis electricity load, and the upper part battery system supplies power to the upper part electricity load. When the upper part battery system runs out, the chassis battery system can supply power to the upper part electricity load through deploying of the power control unit. When the chassis battery system runs out, the upper part battery system can supply power to the chassis through deployingof the power control unit. In addition, through deploying of the power control unit, the two sets of battery systems can work coordinately, and meanwhile supply power to the upper part or the chassisand charge each other. According to the multi-power battery system structure, based on the chassis battery system, the upper part battery system is additionally arranged, the matching flexibility ofthe vehicle battery energy is increased, and the reliability of the vehicle battery system is improved.

Description

technical field [0001] The invention relates to the technical field of electric special-purpose vehicles, in particular to the general layout design of the chassis applicable to electric special-purpose vehicles. Background technique [0002] At present, the chassis layout of pure electric special vehicles basically adopts the arrangement of the battery system on the chassis. Due to the limited layout space of the chassis, the power of current pure electric special vehicles is relatively low. Contents of the invention [0003] The purpose of the present invention is to provide a multi-power battery system architecture for a pure electric special vehicle. [0004] The present invention is achieved through the following technical solutions: [0005] A multi-power battery system architecture for pure electric special vehicles, characterized in that it includes two sets of battery systems, the voltages of these two sets of battery systems can be the same or different, one is ...
