Integrated high-voltage electrical box for battery system

Abstract

The invention relates to an integrated high-voltage electrical box for a battery system. The integrated high-voltage electrical box comprises an upper cover and a casing, wherein the upper cover covers the casing and is detachably connected with the casing; a high-voltage component, a positive and negative electrode input copper bar and two positive and negative electrode output copper bars are mounted in the casing, one end of the positive and negative electrode input copper bar and one end of each of the two positive and negative electrode output copper bars are connected with the high-voltage component, and the other end of the positive and negative electrode input copper bar and the other end of each of the two positive and negative electrode output copper bars are located in the upper side edge position of the casing; a plugging structure which is used for enabling the other ends of the two positive and negative electrode output copper bars and the other end of the positive and negative electrode input copper bar to be safely exposed is arranged on the peripheral side of the upper cover. One input end and two output ends are arranged on a battery case, so that the electrical box has higher compatibility and can adapt to different project demands; the high-voltage component is mounted on the casing, so that the electrical elements are high in integration degree, high in space utilization rate and flexible and convenient to maintain; the plugging structure is arranged on the upper cover, and the high voltage input and output safety of the electrical box is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, 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. Pure electric vehicles with high energy utilization rate and no pollution to the environment are increasingly becoming the direction of the future development of the 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, the hi...

AI Technical Summary

Problems solved by technology

[0003] The electrical system of the current pure electric vehicle battery pack usually uses the form of an electrical installation board to assemble various high-voltage components together. This installation method has scattered components, many connections, takes up a lot of space, and is difficult to install and maintain.

In addition, the existing high-voltage electrical boxes generally have one input and one output, which is poor in versatility and interchangeability, and cannot be applied to different project requirements
