Problems solved by technology

[0003] The battery cell on the electric drive device of the vehicle can be divided into multiple electric boxes, and each electric box can be disassembled separately. The quick-change technology of the electric box of the vehicle is one of the effective ways to solve the slow charging of the battery, that is, to use electricity Sufficient electrical boxes to replace power-deficient electrical boxes, however, when the electrical box is disconnected from the mechanical connection of the vehicle, due to the instability of the mechanical structure, there will usually be some impact on the battery

Abstract

An embodiment of the invention provides an electric box management method, an electric box management device, a computer storage medium, an electric box and an electric driving device, which are applied to the technical field of batteries. In the embodiment of the invention, the electric box comprises a single box control module, wherein the single box control module comprises a link control module, and the link control module is used for controlling the opening and closing of electric connection between the electric box and a carrier, so as to realize the effect of reducing the influence of instability of a mechanical structure on a battery when the mechanical connection between the electric box and the carrier is disconnected.

Description

【Technical field】 [0001] The invention relates to the technical field of batteries, in particular to an electric box management method and device, a computer storage medium, an electric box and an electric drive device. 【Background technique】 [0002] With the continuous development of science and technology and the increase of people's demand for new energy, vehicles powered by batteries have been widely developed. Due to the requirements of the vehicle itself and the distance of transportation, it usually requires an electric drive composed of large-scale batteries. The device provides electricity, and the charging speed of the electric drive device greatly restricts the development of battery technology. [0003] The battery cell on the electric drive device of the vehicle can be divided into multiple electric boxes, and each electric box can be disassembled separately. The quick-change technology of the electric box of the vehicle is one of the effective ways to solve th...
