5V 300A Lithium-ion Batteries Performance Test Battery Cell Testing Equipment
5V 300A Lithium-ion Batteries Performance Test Battery Cell Testing Equipment
Equipment Overview
The equipment is mainly composed of upper computer, intermediate computer, DC/AC module, DC/DC module, lower computer, data acquisition and processing system, etc., and can
real-time collection of voltage, current, capacity, energy and other information of each single battery. Optional support for battery temperature data collection. The collected data is stored in a specially designed database and provides various data statistics, analysis and report generation functions.
