24S Portable Lithium Battery Pack Equalizer For Car Power Battery

120V 24S Portable Lithium Battery Pack Equalizer For Car Power Battery

Introduction

Lithium battery pack balance maintenance instrument is a maintenance equipment for lithium battery packs of new energy vehicles. It can solve the problem of the inconsistency of the battery cells after the power batteries are connected in series, which causes the unevenness of the battery cells to continue to expand, resulting in shortened battery life, reduced cruising range, and even battery failure.

The main design idea is to analyze and judge the deep-level problems of the battery pack by collecting the parameters of the single battery and using intelligent algorithms. Adopting the method of "filling all the strings", the backward batteries are accurately recharged to ensure that each string of single cells is fully charged, and the power difference between the single cells in the group is maintained to the factory level. This eliminates the short-board effect of the battery pack and restores the entire battery pack capacity to close to the factory level.

Features

• The top-aligned balance mode is adopted to allow all cells to be charged in parallel to ensure that all cells are fully charged.

• High-reliability design, self-checking to identify various faults and equipment faults;

• Adopt a mutual certification safety mechanism to ensure that the battery will not be damaged due to the equipment's own failure.

• Using modular design, all modules support plug and unplug, product maintenance is more convenient.

• The equipment is small, portable and light in weight, fully considering the convenience of user portability.

• Support automatic identification of wiring harness and battery type.

• Supports stepless adjustment of the output current, with a range of 0.5-2.5A.

• Supports balanced record data export, built-in 16GB memory card.

• Good equipment stability, stable communication and internal software operation.

• The operation is simple and convenient, with one-button operation.
