A transition box between an electric vehicle battery pack and a high-voltage distribution box

Abstract

The invention discloses an adapter box used between an electric vehicle battery pack and a high-voltage power distribution box. The adapter box comprises multiple input positive electrodes, multiple input negative electrodes, an output positive electrode and an output negative electrode, wherein the input positive electrodes and the input negative electrodes are correspondingly and electrically connected with the positive electrodes and the negative electrodes of the batteries; the output positive electrode and the output negative electrode are electrically connected with the high-voltage power distribution box; the multiple input positive electrodes are connected to the output positive electrode in parallel; and the multiple input negative electrodes are connected to the output negative electrode in parallel. According to the adapter box, the multiple batteries are connected to the high-voltage power distribution box in parallel; the on / off of each battery can be controlled through an independent relay, so that the purpose of independent control can be realized; and in addition, the adapter box is provided with a relay detection apparatus and a signal processing apparatus, so that the working condition of each battery can be monitored in real time, and detection and maintenance of the batteries can be carried out conveniently.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a transition box between a battery pack of an electric vehicle and a high-voltage distribution box. Background technique [0002] Electric vehicle refers to a new energy vehicle that converts the electricity provided by the battery into the mechanical energy of the vehicle movement. At present, the battery life of electric vehicles has become an important parameter for the performance indicators of electric vehicles, and it is the most effective way to enhance the battery life of electric vehicles. It is to increase the capacity of the battery pack, and connecting multiple battery packs in parallel can increase the capacity of the battery pack, so most of the electric vehicles on the market today are multiple battery packs connected in parallel rather than a single battery pack. [0003] At present, in most electric vehicles, multiple battery packs are directly connec...

AI Technical Summary

Problems solved by technology

[0003] At present, in most electric vehicles, multiple battery packs are directly connected in parallel with wires, which is inconvenient to control and detect between the battery pack and the distribution box. If there is a problem with the high-voltage circuit system, it cannot be quickly determined that it is the battery pack. It is still a problem with the high-voltage distribution box, and it is impossible to choose which battery pack to supply power and which battery pack to not supply power.
