Lithium Battery Balance Maintenance Device

1.Product Introduction

This product is a maintenance equipment for lithium-ion batteries in a wide range

of new energy vehicles or electric bicycles. Due to individual differences in batteries, the voltage of individual batteries may vary after prolonged use, and the imbalance in terminal voltage of individual batteries will lead to low battery capacity utilization and incomplete discharge. This is reflected in user use, resulting in shorter battery life. For this purpose, this product uses the “series charging and compensation” method to periodically sample the individual battery, obtain the current voltage parameters, compare them with the set target voltage, and discharge more and charge less. Narrow the voltage difference between individual batteries, maintain them in a higher efficiency range,improve battery life,increase battery life, and provide users with a better user experience.

Functional Features

● Integrated design

No need for external charger or discharge load, simple wiring, easy to operate.8 inch large LCD touch screen operation, simple menu design, fast response, no need for external IPAD or computer uploader.

● High equalization efficiency

All three channels can work independently, can be charged and discharged, high voltage discharge, low voltage charging, charging and discharging can be carried out at the same time, saving time. Charging and discharging can be done at the same time, which saves time.

● High Equalization Precision

Measurement accuracy reaches 2mv, no false scale, no false equalization, no need for manual calibration.

● High safety performance

Designed in line with the concept of automotive electronic functional safety,there are battery reverse  connection, connection line dropout, battery under-voltage, battery over-voltage, output over-voltage, output short-circuit, output over-voltage, and output short-circuit. overcurrent, output overvoltage, out -put short circuit, equipment over temperature, equipment hardware failure and other protection.

● Flexible working mode

The number of channels can be stacked flexibly, and a single channel can reach 100A current after stacking, which can quickly charge and discharge the battery cell with large pressure difference and equalize it. No constraints such as total negative or total positive, cascade, etc., it can realize equalization between the same module, modules, modules and single batteries.

● Depolarization function

Full working cycle depolarization, automatic current reduction when approaching the target voltage to reduce the virtual voltage, real-time sampling of battery voltage and calculation, intelligent adjustment of the battery to be charged to the target voltage. Real-time sampling of battery voltage and calculation, intelligent adjustment of the battery to the final target voltage, no need to manually guard.

● Simple operation

Foolproof operation, guided setting, high degree of intelligence, one-key equalization.

● Portable design

Small size, light weight,easy to carry, can be equipped with air travel case, convenient for field.

● Data  acquisition

Supports local or remote cloud storage and management of maintenance data of each channel, and supports the analysis of big data platform.
