Abstract

The invention discloses a method, device and system for judging the state of a storage battery. The method comprises the steps of obtaining a current voltage value of the storage battery; obtaining charge and discharge time of the storage battery, wherein the charge and discharge time includes charge time and discharge time of the storage battery; and determining the state of the storage battery according to the current voltage value and the charge and discharge time of the storage battery, wherein the state of the storage battery comprises a normal state, an abnormal state and a fault state. The state of the storage battery can be judged on the premise of not installing a storage battery sensor or a storage battery electric eye, the damage of misuse to the storage battery is avoided while the cost is reduced, and the service life of the storage battery is ensured.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a method for judging the state of a storage battery, a device for judging the state of the storage battery and a system for judging the state of the storage battery. Background technique [0002] A battery is a device that stores electrical energy and is a low-voltage DC power supply for a car. Proper use of the battery can prolong the life of the battery, and bad usage habits will shorten the life of the battery. Adverse effects may cause damage to the battery, so the battery needs to accurately judge the state of the battery during use and charge and discharge reasonably. [0003] At present, there are two methods for detecting the state of the battery. One method is to install a battery sensor on the start-stop system, and the other method is to add an electric eye to the battery itself. Installing a battery sensor on the start-stop system of the vehicle is costly...
