Automatic charger of traction accumulator

Abstract

The invention discloses a traction battery automatic charger comprising a transformer and a rectifier bridge. The primary side of the transformer is connected to a power main line, the secondary side is connected to the input end of the rectifier bridge and the output end of the rectifier bridge is connected to a terminal through a fusing protector. The main technical characteristics is that a plurality of regulation taps are arranged on the primary side of the transformer, a detection and control module is formed by a detection unit, a microcomputer processing unit and a switching unit, wherein the detection unit includes a voltage sensor, a current sensor and a temperature sensor, the output end of the detection unit is connected to the input end of the microcomputer processing unit, the output end of the microcomputer processing unit is connected to the input end of the switching unit, the switching unit is correspondingly arranged between the power main line and each regulation tap at primary side of the transformer. The charger intellectualization is achieved according to the invention and the charge process is finished in shortest time with highest efficiency and unattended duty. The battery life is prolonged because of the least heat generation and water loss of the battery during the charge process.

Description

Technical field: [0001] The invention relates to an automatic charger for traction batteries, belonging to the field of automatic charging devices for lead-acid batteries. Background technique: [0002] The accumulator is a secondary battery, which can be used multiple times through a charger. But charging the battery requires certain expertise. During the use of lead-acid battery packs, due to various reasons, the active materials on the individual battery plates cannot be recovered in time, which will result in unbalanced parameters between batteries. This affects the capacity and life of the battery pack and reduces the use value of the entire battery pack. Therefore, it is necessary to charge the battery pack at intervals. Some existing chargers can only perform simple charging operations, and need to be adjusted manually during the charging process. If you do not understand the charging technology, the battery cannot be used properly, and improper operation may even cause...

AI Technical Summary

Problems solved by technology

Some existing chargers can only perform simple charging operations, and manual adjustments are required during the charging process. If you do not understand the charging technology, you will not be able to use the battery properly, or even explode if you do not operate properly.

Although another type of charger is known as an intelligent charger, due to the lack of thorough understanding of battery charging technology, the performance of the charger does not meet the requirements of battery charging, resulting in undercharging or overcharging of the battery, which is easy to damage the battery and greatly reduces the battery life. battery life

Such a charger does not meet the charging requirements of the battery
