Integrated high-voltage electric box for battery system

Abstract

The invention relates to an integrated high-voltage electric box for a battery system. The integrated high-voltage electric box is used for installing a high-voltage electric component of the battery system therein, wherein the high-voltage electric component comprises a positive electric component, a negative electric component and a functional electric component; the electric box comprises an upper cover and an installation base; the upper cover is detachably connected to the installation base; the high-voltage electric component is arranged between the upper cover and the installation base; and one side surface, connected with the upper cover, of the installation base is provided with an installation part for installing the positive electric component, the negative electric component and the functional electric component and separating the positive electric component, the negative electric component and the functional electric component in an insulating manner. According to the electric box provided by the invention, the positive electric component, the negative electric component and the functional electric component in the high-voltage electric component of the battery system are integrated into an integral structure through the arranged installation part, so that the battery system is high in integration degree, high in space utilization ratio, small in installation space and flexible and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of integrated boxes, in particular to an integrated battery system high-voltage electrical box. Background technique [0002] At present, the global automobile industry is facing huge challenges of energy and environmental issues. The current energy utilization rate is high, so pure electric vehicles that do not pollute the environment are increasingly becoming the development direction of the future automobile industry. As the core component of electric vehicles, the safety of electric vehicle power batteries will directly affect the performance and driving safety of electric vehicles. The high-voltage electrical system undertakes the energy transmission task of the entire battery system, and its main function is to connect or disconnect the high-voltage circuit according to the control requirements of the vehicle; when the current of the power battery system is too large or the circuit is short-circuited, ...

AI Technical Summary

Problems solved by technology

At present, the electrical system of the battery pack of pure electric vehicles usually uses the form of an electrical installation board to assemble various high-voltage components together. difficulty

The existing high-voltage electrical box has low integration, poor versatility and interchangeability, and the high-voltage components are not separated by insulating plates, which is prone to short-circuit danger
