A battery management method, device and system for an electric vehicle

Abstract

The invention discloses an electric vehicle battery management method, device and system. The management method comprises the steps that battery identity information of a vehicle is acquired; the state of a battery is detected to obtain detection data, wherein the detection data comprises one or more of battery discharge information, a voltage value, a current value and an electric quantity value; a mapping relation between the battery identity information and the detection data is established. According to the electric vehicle battery management method, various state data of the battery can be detected, analyzed and processed, and corresponding processing instructions are made if analysis results are abnormal states, so that effective management of the battery is achieved, and the service life of the battery is prolonged.

Description

technical field [0001] The invention relates to the field of battery monitoring, in particular to a battery management method, device and system for an electric vehicle. Background technique [0002] Many electric forklifts or other electric vehicles are equipped with battery power / voltage detection and display equipment (fuel gauge), but these devices can only provide current status information, and cannot provide complete information during battery use (such as battery discharge length of time, charge saturation, etc.), and cannot save or transfer these data. [0003] At present, the forklift electricity meter on the market can only display the current electricity information, and does not record the information of the entire discharge process: such as the voltage at the beginning of the discharge, whether the battery is fully charged, the curve of the battery discharge, the length of the battery discharge, etc.; it is also impossible to obtain The identity of the battery...

AI Technical Summary

Problems solved by technology

[0002] Many electric forklifts or other electric vehicles are equipped with battery power / voltage detection and display equipment (fuel gauge), but these devices can only provide current status information, and cannot provide complete information during battery use (such as battery discharge length of time, charge saturation, etc.), and cannot save or transfer these data

[0003] At present, the forklift electricity meter on the market can only display the current electricity information, and does not record the information of the entire discharge process: such as the voltage at the beginning of the discharge, whether the battery is fully charged, the curve of the battery discharge, the length of the battery discharge, etc.; it is also impossible to obtain The identity of the battery, that is to say, it is impossible to bind the identity of the battery with the data of the discharge state of the forklift; there is also no function of data storage, which cannot be checked after the event, and the data cannot be sent to the background server

[0004] A forklift is generally equipped with multiple batteries. As far as multiple forklifts are concerned, there will be a large number of batteries. These large numbers of batteries lack effective data management, resulting in shortened battery life and poor discharge capacity, causing huge damage to the enterprise. Financial losses, while excessive use of batteries can also lead to environmental pollution
