Problems solved by technology

[0004] At present, the power lithium battery box produced on the market has a single structure. The power battery box assembly is composed of battery cells connected in series and parallel to form a module, and the modules are then connected in series to form a PACK. This structure is simple and the cost is relatively low. But it lacks the corresponding active safety system, which is as terrible as the lack of active safety systems such as ABS or ESP in cars.

Embodiment 1

[0029] Such as figure 1 The car power lithium battery box with active safety system shown includes the first CAN bus, the second CAN bus, the third CAN bus, several lithium battery packs, several BMU acquisition terminals, BMS controller, fire extinguisher host, Fire extinguisher, VCU controller, display screen, manual fire extinguishing operation panel and motor control module, the BMS controller is equipped with the first CAN bus interface, the second CAN bus interface and the third CAN bus interface, and the VCU controller and fire extinguisher host CAN bus interface, the CAN interface of the VCU controller is connected to the first CAN bus interface through the first CAN bus, and the CAN bus interface of the fire extinguisher host is connected to the second CAN bus interface through the second CAN bus;

[0030] The VCU controller is provided with a first serial port, a motor control terminal and a key input terminal, the input terminal of the display screen is connected to...

Embodiment 2

[0038] Such as image 3 As shown, the control method supporting the vehicle power lithium battery box with active safety system is realized by the vehicle power lithium battery box with active safety system described in embodiment 1, which includes the following steps:

[0039] Step 1: Each BMU acquisition terminal collects the voltage data and temperature data in its corresponding lithium battery pack in real time; at the same time, the fire extinguisher host collects the fire alarm data of each lithium battery pack in real time, and generates fire alarm data CAN messages;

[0040] Step 2: Each BMU processes the voltage data and temperature data into a voltage and temperature CAN message, and uploads the voltage and temperature CAN message to the BMS controller through the CAN bus;

[0041] Step 3: The BMS controller and the fire extinguisher host exchange fire alarm data CAN messages and voltage and temperature CAN messages through the CAN bus; the present invention monitors...

Abstract

The invention discloses an automobile power lithium battery box with an active safety system and a matched control method, and belongs to the field of automobile safety. The automobile power lithium battery box comprises a first CAN bus, a second CAN bus, a third CAN bus, a plurality of lithium battery packs, a plurality of BMU collection terminals, a BMS controller, a fire extinguisher host, a fire extinguisher, a VCU controller, a display screen, a manual fire extinguishing operation panel and a motor control module. According to the box and the method, an early warning of fire alarm security risks is realized; and an automatic fire extinguishing function after an early warning of the battery box is invalid or a fire breaks out suddenly is realized.

Description

technical field [0001] The invention belongs to the field of automobile safety. Background technique [0002] With my country's policy support in the field of new energy, especially in the field of new energy for automobiles, the development of pure electric vehicles with the theme of new energy in my country has been very popular in recent years, and various new energy automobile factories have sprung up like mushrooms. Appear. The development of pure electric vehicles has of course led to the development of power lithium batteries, but considering the current situation in the field of power batteries in my country, the blind pursuit of output ignores the most important safety system. The battery will generate a lot of heat during the charging process, which will cause the temperature of the surrounding parts of the battery to increase. During the charging process of the lithium battery, once the BMS management system fails and overcharge occurs, the temperature of the batt...
