Problems solved by technology

[0003] Although the service life of the battery is generally about 2-3 years, there will be no obvious early symptoms before it breaks down or dies. The direct manifestation may be that the vehicle does not start smoothly after overnight or the battery cannot store electricity. In seve

Abstract

The invention discloses a method and a system for detecting vehicle storage battery service life. The method includes: the OBD interface voltage change curves of various car types are collected in advance, type classification is performed on the voltage change curves according to the service life of storage batteries, the real-time voltage change curve of the OBD interface of a current car type is monitored and is matched with the collected voltage change curve of the same car type so as to predict residual service life of the storage battery of the current car type, if the residual service life of the storage battery is smaller than a preset value, and a warning for replacing or maintaining the storage battery is given out. By the method, a user does not need to worry that a car fails due to the fact the storage battery has no signs before being used up, pre-warning of the storage battery service life can be achieved, the user can replace or maintain the storage battery in advance, damage to car electric elements is lowered, and system safety is increased.

Description

technical field [0001] The invention relates to the technical field of vehicle battery detection, in particular to a method and system for detecting vehicle battery life by detecting OBD interface voltage changes. Background technique [0002] A vehicle's battery, also known as a battery, is a device that converts chemical energy into electrical energy. Its function is to supply electricity to the electric starting system of the engine. When the vehicle is ready to start, the battery will discharge to provide power to the electric starting system, and the electric starting system will drive the flywheel and the crankshaft to rotate, thereby starting the vehicle. When the power supply of the engine is insufficient or not started, it provides power for the electrical appliances in the car, such as the audio system and lighting system. When the engine starts to supply power normally, the battery will collect and store electric energy for future use. Batteries are an essential ...
