AI Technical Summary

Technical Problem

The existing battery pack structure design of heavy-duty trucks results in excessive height, increasing the risk of collision between the battery pack and the battery compartment, and affecting installation accuracy and safety.

Method used

An innovative internal layout is adopted, dividing the battery pack frame into upper and lower layers to house the high-voltage junction box, control box, and air conditioning compressor, respectively. The water-cooled water tank is located on the side of the battery pack. The spatial layout is optimized through a horizontal compressor and staggered main beam structure, reducing the overall height and width of the battery pack.

Benefits of technology

By reducing the overall size of the battery pack, especially its height, the risk of collision during battery replacement in side-mounted electric vehicles is reduced, improving the safety and efficiency of battery replacement.

Abstract

The application provides a truck battery pack and a battery replacement method thereof, which comprises: a battery pack framework, an internal space defined by the battery pack framework is divided into an upper layer and a lower layer; a first space area for accommodating a high-voltage junction box, a second space area for accommodating a high-voltage control box and a third space area for accommodating an air conditioner compressor are arranged in the lower layer; a battery pack is arranged in the upper layer of the battery pack framework in a matrix manner, a water cooling pipeline of the air conditioner compressor is connected with the battery pack, and coolant flows out from the air conditioner compressor, passes through a path in a counter-gravity direction and reaches the battery pack in the battery pack; and a water cooling water supplement tank is arranged on one side of the battery pack with the highest position in the battery pack, and the water cooling water supplement tank is connected with the battery pack and the air conditioner compressor. The application can greatly reduce the height and overall volume of the battery pack, thereby reducing the collision between the battery pack and the battery compartment when the side-mounted electric vehicle is replaced with a battery, and improving the safety and efficiency of replacing the battery.
