Abstract

The invention discloses a device and a system for online repairing a storage battery for an electric vehicle. A current exciting unit is controlled to output discharging current with adjustable size and frequency by the device according to the detected battery voltage signal under the condition that heating of the battery and travelled distance of the vehicle are not influenced, so that the battery is repaired online; simultaneously, the battery is difficult to vulcanize in a charging or idle state due to continuous current repair, so that the effect of preventing vulcanization is achieved. Besides, the device has a low-voltage detection function; and with the adoption of the device, the over-discharge of the battery can be effectively prevented, thereby the battery is protected. According to the technical proposal provided by the invention, the battery repairing process is simple, the repairing condition applicability is strong and the repairing efficiency is high, so that the battery is online repaired under any condition, and the service life of the battery can be improved by more than 30%.

Description

technical field [0001] The invention relates to the technical field of battery maintenance, in particular to a device and system for online repair of batteries of electric vehicles. Background technique [0002] Lead-acid battery is a widely used power source, which has the advantages of good reliability, low price and easy availability of raw materials. In recent years, with the continuous development of electric bicycle technology and its economical, practical and environmentally friendly advantages, the market share of electric bicycles has continued to increase, and the demand for lead-acid batteries has continued to increase. During the use of the battery, if the battery is not used and maintained properly, due to incomplete discharge, excessive discharge or long-term non-use in the discharged state, vulcanization occurs, and coarse lead sulfate crystals are formed on the substrate. This crystal conducts electricity. Poor performance and large volume, the crystallized ...
