Product Description

768 Channels Ni-MH Battery Charge Discharge Formation Machine

 

Equipment Composition

This equipment is mainly composed of a computer (computer provided by customer), a communication interface and a battery forming machine.

The battery forming machine is composed of clamp and plate body for placing the clamp, a main board, a charge and discharge switch power supply, machine and a control panel.

 

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 -ΔV (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.

6.Voltage sampling by zero-current mode (i.e. closing the output current of the constant-current source at the moment of tapping voltage and restoring the current after sampling) can effectively reduce the misregistration phenomenon caused by excessive contact resistance of fixture and reduce the failure rate of fixture while ensuring the sampling accuracy.

7.Current settings are set by computer software or keyboard operation.

8.It has the function of data power-off protection, and can continue to operate after power is available.

9.When charging or discharging, if there is no current in a circuit, there will be an indicator lamp to alarm, and each set of constant current sources has a fault indicator lamp.

10.Each PC can connect 1-6 devices.

11.It has the function of automatic discharge recharge to ensure that each battery is discharged according to the given current. Even if the last battery is left, it can discharge according to the given current.

12.Save the test results and process the data.

1) Indicating the capacity of batteries in any segment (up to 16 segments).

2) The complete charge-discharge curve of each station can be set and saved (which needs to be connected to the upper computer to save).

3) Batteries can be sorted according to pre-operation settings.

4) Provide battery sorting function.
