Insulating, heat-dissipating and easily-detached type battery box for formula electric car

Abstract

The invention discloses an insulating, heat-dissipating and easily-detached type battery box for a formula electric car. The insulating, heat-dissipating and easily-detached type battery box comprises an insulating box and a battery box cover for covering the opening of the insulating box, wherein the insulating box comprises a box bottom plate, a pair of heat dissipation side plates symmetrically arranged on the box bottom plate, and a high-voltage lead front plate and a high-voltage lead back plate which are arranged oppositely, wherein a battery module isolation inner plate and a heat dissipation fan air-cooling clamping plate parallel to the heat dissipation side plates are arranged in the insulating box; and a heat dissipation fan for performing forced air cooling on battery modules in the box is fixed on the heat dissipation fan air-cooling clamping plate. The battery box provided by the invention is light in weight, high in space utilization, high in mechanical strength, simple in box structure, convenient to manufacture, and convenient and rapid to install, detach and maintain; and meanwhile, the battery box is good in waterproof, sealing, heat-dissipating and ventilating performance, and capable of rapidly discharging harmful gases with potential safety hazards from the battery, effectively dissipating heat from the battery box, and improving the operational reliability of a battery system.

Description

technical field [0001] The invention belongs to the field of energy and power for pure electric racing cars, and in particular relates to an insulating and heat-dissipating easily disassembled battery box for a formula electric racing car. Background technique [0002] With the rise of Formula Student racing competitions, pure electric formula racing has gradually attracted widespread attention due to its excellent power, economy and environmental protection. Due to the particularity of the Formula Student electric racing car, different requirements are put forward for its power, economy, applicability and other performances compared with traditional fuel racing cars. The engine suitable for traditional fuel racing is replaced by an electric motor with better acceleration performance, and the traditional fuel as a power source is replaced by more environmentally friendly electric energy. In order to ensure that the high-voltage battery module of the formula electric car can...

Problems solved by technology

At present, most battery boxes in China have the problems of bulky boxes, low space utilization, insufficient mechanical strength, and complex box structures, which lead to complicated manufacturing processes, difficult installation, and difficult disassembly and maintenance. At the same time, the design of air-cooled boxes faces waterproof and sealing Due to the conflict between heat dissipation and ventilation, most battery boxes adopt a fully sealed design with an explosion-proof valve, which not only causes the internal battery module and battery management system to not get effective heat dissipation, but also cannot eliminate the discharge of the battery in the first place.
