Problems solved by technology

[0003] The technical problem solved by the present invention is to provide an automatic limit and short-circuit replenishment system for battery packs. The system adopts a sealed infusion, a floating bucket type switch valve, and a split-flow drip screen with a multi-hole enlarged diversion area structure. The inlet pipe or outlet pipe with gas storage and anti-short-circuit function at the switch of the float bucket realizes the centralized automatic anti-short-circuit replenishment and centralized gas discharge of the battery pack. This system is safe and reliable, replacing manual maintenance one by one. Convenient and fast, low cost and less maintenance, effectively solve the technical problems of difficult position limit and low safety of battery replenishment operation

Abstract

The invention discloses an automatic limiting and short-circuit-proof liquid supplementing and feeding system for a storage battery pack. The automatic limiting and short-circuit-proof liquid supplementing and feeding system comprises the storage battery pack composed of a plurality of single storage batteries; a liquid supplementing and exhausting combined cover of each single storage battery is provided with an automatic limiting and short-circuit-proof liquid supplementing and feeding device; a liquid supplementing and feeding hole of the automatic limiting and short-circuit-proof liquid supplementing and feeding device is connected with a liquid supplementing and feeding pipe; one end of the liquid supplementing and feeding pipe is connected with a concentrated liquid storage tank and the other end of the liquid supplementing and feeding pipe is sealed; an exhausting hole of each automatic limiting and short-circuit-proof liquid supplementing and feeding device is connected with an exhausting pipe; one end of the exhausting pipe is sealed and the other end of the exhausting pipe is communicated with the external atmosphere through an exhausting check valve. The automatic limiting and short-circuit-proof liquid supplementing and feeding system is convenient and rapid to operate, low in cost, less in maintenance and safe and reliable to use.

Description

technical field [0001] The invention belongs to the technical field of liquid replenishment systems for battery packs, and in particular relates to an automatic position-limiting and short-circuit-proof replenishment liquid system for battery packs. Background technique [0002] During the charging process of the battery, the side reaction of electrolyzing water will occur. During the use, the water will be continuously consumed and gas will be generated. Generally, the positive electrode will produce O 2 , the negative electrode produces H 2 , In the process of use, there will inevitably be a phenomenon that some single batteries or the whole battery pack are short of liquid. The original technical design of the battery adopts the method of reserving a large liquid storage space on the internal plate of the battery, and storing more liquid in advance to achieve the purpose of extending the maintenance cycle. This original technology has the following defects: 1. During use...
