Battery Management System With Integrated Voltmeter For Over/Under Voltage Protection And Timing Control For Optimal Charge/Discharge Communication

1. Battery charge and discharge intelligent control;

2. You can set the charge and discharge time;

3. With serial communication function, real-time monitoring of the working status of the relay through the serial port;

4. Additional signal output, when the relay to meet the conditions, the output high, you can control other equipment.

Voltage upper limit: UL1, voltage lower limit nL1, the voltage upper limit is greater than the voltage lower limit (UL1> nL1)

U-1: Charging measurement: When the measured voltage is lower than the lower limit voltage, the relay pulls above; the upper limit voltage, the relay is disconnected.

U-2: charge measurement time control: set the charging time (OP); when the measured voltage is lower than the lower limit voltage, the relay pull, and then start the countdown OP time, the end of the timer, the relay off; when the measured voltage is higher than the upper limit voltage , The relay is disconnected.

U-3: Discharge detection: When the measured voltage is lower than the lower limit voltage, the relay is off, above the upper limit voltage, the relay pulls;

U-4: discharge detection time control: set the discharge time (OP); when the measured voltage is higher than the upper limit voltage, the relay pull, and then start the countdown OP time, the end of the timer, the relay off; when the measured voltage below the lower limit voltage , The relay is disconnected;

U-5: voltage in the range, the relay pull: when the measured voltage between the upper and lower limits, the relay pull, the other circumstances open;

1: Power supply voltage: DC6--40V, voltage detection range DC 0--60V, suitable for less than 60V of the various batteries, voltage measurement error ± 0.1V.
