Description

Introduction

The feeder-type energy-saving battery testing equipment is the latest generation of energy-saving battery testing equipment based on PWM high-frequency power feedback technology that our company has developed after many years of research and development in China. It is widely used in lithium-ion batteries, nickel-hydrogen nickel-cadmium batteries. Formation and volumetric testing. The product's stability, energy saving, precision and quality have been welcomed and praised by many battery industries. The overall technology is currently at the leading domestic level and is leading the continuous advancement of technological changes in the battery industry.

The structure and appearance of the equipment

The structure of this equipment is mainly composed of the following parts:

1. One CPU board, the whole cabinet sends and controls uniformly.

2. There are 32 eight-channel constant current plates, arranged evenly in four doors.

3. 4 bidirectional inverter power supplies, each for 8 constant current boards.

4. Two keyboard boards, front and rear double-sided operation.

5. 16 sets of quick clamps, each with 16 channels, equipped with 16 battery plastic trays, suitable for 32131 batteries.

System structure and working principle

Working principle

The equipment is controlled by a computer connection, sending instructions and collecting data, etc.; the keyboard can manually operate the equipment, displaying parameters and status; the constant current board is commanded by the CPU, and has constant current and constant voltage functions; when the battery is charged, the bidirectional power supply converts AC power to 12V Direct current, through the constant current board to realize the charging control and detection of the battery; when the battery is discharged, the process is opposite to charging, first the battery voltage is raised to 12V through the constant current board, and then the direct current is converted into alternating current through the bidirectional power supply. Into the AC power distribution network of the factory, thus realizing the energy feedback of the discharged electric energy of the battery.

Significant power-saving effect: According to actual measurement, the power consumption of the device during charging is reduced by more than 40% compared with that of traditional devices. The comprehensive power-saving rate is more than 60%, and the power consumption is more than 60%, which saves a lot of cost for battery manufacturers.
