Problems solved by technology

[0005] The battery is a vulnerable part and has a limited lifespan. If the health status of the battery can be known in time, maintenance work can be done in advance. However, in the existing technical solutions, the health status of the battery cannot be accurately judged
Moreover, the opening and closing of the discharge module is not controlled, which affects the battery life

Abstract

The invention provides a device and method for detecting a health condition of a vehicle-mounted battery. The battery is used as a backup of a vehicle-mounted terminal power supply, the detection device comprises a battery internal resistance detection module and a controller, a first end of the battery internal resistance detection module is connected with a positive electrode of the battery, and the second end of the battery internal resistance detection module is connected with the power ground; the controller detects the no-load voltage of the battery and the on-load voltage of the battery when the battery and the battery internal resistance detection module form an access, and determines the internal resistance of the battery based on the no-load voltage and the on-load voltage so as to judge the health condition of the battery.

Description

technical field [0001] The present application relates to the technical field of commercial vehicle batteries, in particular to a detection device and a detection method for the health status of a vehicle battery. Background technique [0002] Commercial vehicles are generally equipped with vehicle-mounted terminals. Vehicle-mounted terminals are used in the field of vehicle safety driving monitoring and remote monitoring of the Internet of Vehicles. The main functions include Beidou position monitoring, video monitoring, driver behavior monitoring, and vehicle scheduling. Monitoring information is very important. [0003] Therefore, in order to ensure the integrity of monitoring information, a battery is installed in the vehicle-mounted terminal to back up the power supply, such as figure 1 shown. When the car power supply has power, both the power module and the discharge module are turned on, and VCC1 is greater than VCC2, then the car power supply supplies power to the ...
