• Units can run entirely independently of each other at a single point in the system, with each battery having an independent constant current and constant voltage source, and run stably without impacting on each other.
• The accuracy of the equipment is 0.1% and of very high stability.
• The software is highly functional and has a friendly man machine interface.
• The four-wire test interface ensures high measurement accuracy.
• The equipment has a modular design concept for easy maintenance.
Equipment Design
• Independent CPU board, double keyboard board, independent operation of front and back sides, unified transmission control of the whole cabinet.
• 8-channel constant current constant voltage control module.
• Double inverter module (AC/DC).
• Flat-head clamp, tray form manual open clamp.
System Composition
• The equipment consists of lithium-ion battery pack equipment.
• Personal computer with USB interface (not supplied).
• USB to 485 interface converter & communication line or Category 5 communication line with crystal head.
• Battery scanning equipment.
• Product software.
System Principle
• The equipment is computer-controlled through a connection to a computer to send instructions and collect data, etc.; the keyboard can manually operate the equipment displaying therefore the parameters and status; the constant current board is instructed by and controlled by the CPU, and has constant current and constant voltage capabilities, whilst charging the battery the bidirectional power supply converts the alternating current to 12V direct current, and the constant current board controls and tests the charge (current) into the battery; During the discharging process, the battery voltage is raised through the constant current board to 12V and then the DC power is converted into AC power through the bidirectional power supply to feed it to the AC power factory distribution netpoike for energy feedback of the battery atual energy discharges.
• The test will have a significant power retrievable: broadly stated when actual measurement was conducted, the power consumption of the unit during charging had been reduced more than 40% overall versus the measured power consumption of any operating device. The comprehensive power retrievable rate exceeds 60%, as did power conversion rate. A significant and bankable cost savings is therefore realized for battery manufactures.
