Abstract

The invention provides a T-BOX standby battery control device and method. By setting over-discharge critical power value of a standby battery, health index, current power value and current working current of the standby battery are obtained, the battery life of the standby battery is calculated, and task executing time needed by processing a preset task is obtained; and a battery control strategyis selected according to a relation between the task executing time and the battery life; and therefore, the over discharge of the standby battery is avoided, and the service life of the standby battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of battery control, in particular to a T-BOX backup battery control device and method. Background technique [0002] T-BOX is the abbreviation of Telematics BOX. It is an important part of the Internet of Vehicles system. It mainly completes the two-way transmission of data inside and outside the car, and safe and reliable communication. It can realize in-car entertainment, security and anti-theft, information collection, remote control, air upgrades, and applications. interactive functions. [0003] At present, there is a backup battery in the T-BOX. Its function is to continuously provide working current for the T-BOX after the main power supply vehicle battery is cut off, so that when the car fails, the T-BOX can still work normally for a period of time. , to complete the information upload work of the current state of the vehicle. [0004] However, the capacity of the backup battery is limited, and if ...
