Temperature (YJ01, YJ02)
- Pin 1, 2 is connected with a NTC thermistor for temperature monitoring.
According to temperature variation in the module, the resistance of the thermistor is
determined. The resistance measured through the thermistor relates to temperature
according to the DK Sensor 10K@ 25
℃
resistance to temperature chart for the
appendix I.
- Pin 3, 4 are not used.
Temperature & Over voltage alarm (YJ03, YJ04)
- Pin 1, 2 is connected with a NTC thermistor for temperature monitoring.
- Pin 4 is connected with monitoring connector output signals receiver
circuit’s
ground.The output signals are isolated from the capacitor voltage and from
chassis ground.
- When a cell in the module goes into over voltage condition, pin 3 has alarm signal.
When every cell voltage is not over voltage state, the output of Pin 3 is high. If any
cell in the module is exceeding 2.6V or 2.9V, the voltage balancing circuit
becomes active and starts to discharge the cell.
- Nevertheless, if voltage keeps rising due to higher current, over voltage alarm
become operating at 2.8V or 3.1V as output of Pin 3 becomes low. Then, user
should stop charging.
- In order to use the signal, the user needs to attach a pull-up resistor(typically 1
kΩ)
to pin 3 and a 5V supply.
