1.The equipment is composed of 8~10 machines units, and each unit contains 8 independent 4-electrode testing channels; each of the channels is equipped with programmable constant-current supply, constant-voltage supply and load pulse source. The basic functions by support testing software include: battery load-voltage platform, current platform, capacitance platform, voltage step and cyclic life. (Refer to the related software introduction for the detailed testing performance.) 2.Energy-saving ¡°PWM Two-way Transduction Technology¡± is utilized for the equipment¡¯s high precision of testing and high reliability of operation as well as the saving of considerable electric power applied in testing. 3. Technical standards: Current output: 0.2A-20A Voltage output: 5V-40V Precision of current: 0.1%RD+0.1%FD
