Abstract

The invention discloses a multifunctional power-off acquisition protection device, which comprises a shell, a working copper bar conductor, a cut-off piston, an ignition trigger and a pair of first signal acquisition terminals, and is characterized in that the shell is internally provided with a cut-off working chamber; the working copper bar electric conductor is inserted into the shell in a penetrating manner, at least one cutting reed is arranged in the cutting working cavity, and the cutting reed is an alloy resistor part made of an alloy material; the cut-off piston is arranged in the cut-off working chamber in a manner of moving up and down and is positioned right above the cut-off reed; the ignition trigger is arranged on the shell and used for driving the cut-off piston to move so as to cut off the cut-off reed when the ignition trigger is triggered to be started. The pair of first signal acquisition terminals is electrically connected to the two ends of the working copper bar conductor respectively. The multifunctional power-off acquisition protection device can realize the functions of current monitoring, overload protection, loop breaking and temperature monitoring.

Description

Technical field [0001] The present invention relates to the technical field of power-off protection devices, and in particular, to a multi-function power-off acquisition protection device. Background technique [0002] At present, electric vehicles generally have battery, motor and electronically controlled three-power system. These three major components are connected through high-speed communication bus and is the most important part of the electric motor electrical system. Among them, the battery system is mainly composed of power battery pack and BMS (battery management system), and the power battery pack includes a plurality of power cells and connecting devices, high voltage distribution units, wire, etc. by a string, in combination. BMS is responsible for monitoring the battery's state, controlling the charge and discharge of the battery, and interacts the status information of the battery with the motor driver, the vehicle controller. [0003] At this stage, the power-off...
