SOC Monitor PowerTech

 

The SOC Monitor is a monitoring device for lithium batteries. It incorporates a precision shunt (0.2 milliohm) that provides better accuracy than Hall-effect sensors. This device can be used to measure voltage and current with great accuracy and estimate the SOC (State of charge) of a battery with great accuracy. battery with great precision.


All information (tension, current, SOC) is sent to an external controller via several communication protocols. external controller. Settings such as the rated capacity of the battery can be configured by sending a simple command to the device.

Measuring the current


The device incorporates a high-precision shunt resistance that allows you to measure both small currents and larger ones.
bigger. For greater accuracy, the software calibrates the current on small and large currents.
Current.
If the current to be measured is greater than 100A, it is possible to connect an external shunt resistance through the connector.
through the connector.

 

Measuring battery voltage


The device measures the battery voltage every second. Good precision is achieved by calibrating the two voltage measurements, large and small.

 

Measuring temperature


The monitor can measure an external temperature. In this case, a "thermistance" must be plugged into the "THERMISTOR" connector.

 

 

communication


Several means of communication are integrated into the SOC Monitor:

Insulated CAN Bus (2.5kV)
I2C
LED display (SOC information only)
PWM (SOC information only)

 

Port series:

RS232 (switch to position 232/485).
RS485 (MODBUS switch on position 232/485).
Bluetooth (switch on the BLE position).
TTL (switch on TTL position).
