Vehicle-mounted lithium battery remote management system

Abstract

The invention discloses a vehicle-mounted lithium battery remote management system. The vehicle-mounted lithium battery remote management system comprises a remote control module, a lithium battery pack positioned in a vehicle, a battery parameter collection module, a charging-discharging control module, a heat dissipation module, an alarming module, a main control module, a CAN bus module, a fullvehicle controller, a vehicle-mounted display and a wireless module; the charging-discharging control module is used for realizing charging-discharging management of the lithium battery; the batteryparameter collection module is used for collecting parameters in the operating process of the lithium battery pack and transmitting the data to the main control module; the alarming module is used forgiving out alarm in abnormal conditions; the full vehicle controller is used for performing information management and dispatching through a CAN bus; the vehicle-mounted display is used for displaying the data information of the lithium battery pack; and the remote control module is used for performing remote monitoring on the condition of the lithium battery pack. By virtue of the vehicle-mounted lithium battery remote management system, the problems caused by overcurrent, overvoltage, undervoltage, high temperature and imbalance charging can be prevented, so that operational safety of the lithium battery can be improved, and the service life of the lithium battery can be prolonged.

Description

technical field [0001] The invention relates to the field of lithium battery management, in particular to a remote management system for a vehicle-mounted lithium battery. Background technique [0002] Electric vehicles are an important direction for the development of the automotive industry, and automotive lithium batteries are key components of electric vehicles. However, under conditions such as overheating, overcharging, overdischarging, extrusion, and vibration, the lithium battery may shorten or damage the life of the lithium battery, and may also cause fire and explosion accidents. major factor. In order to maintain the reliable operation of lithium batteries, real-time monitoring of the operating status of lithium batteries is a necessary process. The electric vehicle battery management system is an important link connecting the vehicle power battery and the electric vehicle. Its main functions include: real-time monitoring of battery physical parameters; battery ...
