System for managing continuous status of batteries of electric motorcar

Abstract

The invention relates to a system for managing the continuous status of batteries of an electric motorcar, comprising a battery box replacing unit, a charge inspection maintenance station unit and a network control centre unit, wherein the battery box replacing unit comprises a battery unit module formed by connecting more than two single batteries in series, battery monitoring modules respectively matched with each single battery correspondingly, a battery status collection module and a battery box management module; the charge inspection maintenance station unit comprises more than two chargers, charge management modules corresponding to each charger and a charge station database management computer communicated with more than two charge management modules; and the network control centre unit receives data sent by the charge station database management computer and sends database data of the corresponding battery box replacing unit to the charge station database management computer. The invention can dynamically carry out analysis and judgment on the batteries in the use process, measure and maintains the batteries in time in the charge process of the batteries, prolong the service life of the batteries, improve the safety performance of the batteries, and reduce the use cost of the batteries.

Description

technical field [0001] The invention relates to a continuous state management system of an electric vehicle battery, which belongs to the technical field of electric vehicle batteries. Background technique [0002] The biggest feature of electric vehicles is that they have little or no emission of pollution during driving, low heat radiation, low noise and environmental friendliness. The core power source of electric vehicles is high-power batteries. These high-power batteries use single cells in series to obtain high-voltage output and provide electric energy for electric vehicles. In order to improve the service life of electric vehicle batteries and ensure the safety of electric vehicles during driving and charging and discharging, it is often necessary to monitor single batteries and battery cells. The battery management system of the electric vehicle in the public technology currently only monitors the voltage, current and temperature of the single battery during the c...

AI Technical Summary

Problems solved by technology

On the one hand, batteries on electric vehicles are usually maintained regularly, such as once a year. By the time of maintenance, battery damage and fatigue have accumulated for a certain period of time. Although testing is relatively easy to find problems and solve them, maintenance at this time is often due to The problematic battery cells have been softly damaged, that is, the fatigue has accumulated to an irrecoverable level and can only be replaced, and these batteries that need to be replaced are far from reaching their effective life. At present, the problem has accumulated due to missing the best maintenance time of the battery Damage to the battery is a common problem in the use of car batteries

On the other hand, the H generated during the driving and charging of electric vehicles 2 CO and CO are both flammable and explosive gases, and their concentration and pressure are important factors affecting the safety performance of electric vehicles, so there are serious safety hazards
