512 Ni-H Channel Battery Tester
Main Performance of Equipment
1.Double-sided structure, each battery forming machine can control and detect 768 Ni-MH or Cd-Ni batteries by constant current charging and discharging.
2.A light-emitting diode is installed on each clamp as an over-voltage and under-voltage bypass register display. After discharge, it is used to indicate battery capacity sorting.
3.AVR single-chip computer is used as the control center, which can be controlled by the upper computer or separated from the upper computer to complete constant current charging, discharge testing and capacity sorting.
4.Real-time detection of the charging and discharging voltage of each battery. When charging, the bypass is stored when the voltage exceeds the set upper limit or —△V (preset) occurs, and the corresponding battery indicator lights up. When the discharging voltage is lower than the lower limit set by the user, the bypass is registered and the corresponding battery indicator is lit.
5.Every 8 batteries (in series) have a set of constant current sources, which are sampled by analog switch switching. There are 96 sets of constant current sources in the whole machine. The damage of one group of constant current sources will not affect the normal operation of other channels, modular structure, low failure rate and convenient maintenance.
