Since most existing mining trucks are fuel-driven, they may generate a large amount of pollutants during operation, which will have an impact on the environment. Generally, electric vehicles do not generate fuel pollutants. However, electric vehicles do not include hydraulic systems, which are the core power of mining trucks. Therefore, it is difficult to directly install the entire vehicle system of electric vehicles on mining trucks.

In view of this, the embodiment of the utility model provides a whole vehicle system, which uses electricity as the core drive to meet the work of various modules of the mining truck.

The following is a detailed description of the implementation of the present invention in conjunction with the specific drawings:

In some cases, the battery module 13 of the vehicle system has sufficient power and the grid needs compensation. At this time, the general control module 11 can control the charging and discharging module to be in the discharge mode, so that the power in the battery module 13 is released to the grid through the charging pile, so as to achieve peak shaving and valley filling of the grid, maintain the stability of the regional grid, or avoid the battery power of the mining truck being too high.

In the embodiment of the present utility model, the main control module 11 can also be connected to the hydraulic system drive module 17, the electric wheel drive module 18, the liquid cooling module 15 and the fan module 16 respectively.
