Abstract

The invention discloses a battery emergency disconnection system based on accurate measurement. The battery emergency disconnection system comprises a high-voltage electric load, a processor unit anda battery, wherein the battery is electrically connected with a burning explosion type fuse and a copper bar; the burning explosion type fuse is electrically connected with a high-voltage electric load through the processor unit, the copper bar is electrically connected with a temperature sensor through the processor unit, meanwhile, the copper bar and the temperature sensor are electrically connected with a relay, and the relay is electrically connected with the high-voltage electric load. According to the battery emergency disconnection system, the loss of charging and discharging of the battery is reduced through an alternative scheme, the action time of the fuse is prolonged, the current coverage range of the fuse for battery protection is increased, and the thermal runaway risk of thebattery due to overcurrent is reduced.

Description

technical field [0001] The invention relates to the technical fields of automobile battery management, battery protection and fault response, in particular to a battery emergency disconnection system based on precise measurement and a method for using it. Background technique [0002] With global warming and the consumption of non-renewable energy, countries are actively promoting the development of new energy industries. In this context, new energy vehicles are developing rapidly. In order to improve the performance and endurance of vehicles and reduce energy consumption per unit mileage, batteries with higher energy density and higher discharge capacity are adopted. This requires that the electrochemical reaction of the battery must be more active, and the problem is that the battery is more susceptible to failure and thus leads to thermal runaway. The diagnosis of battery failure and effective response become the key to protecting the battery system and even new energy ve...
