BMS HV Monitor (BMS High Voltage Monitoring Solution)

GXSC BMS HV Monitor solution can support the total voltage and current collection of battery packs, insulation detection and other functions, to meet the current high-performance requirements of electric vehicles/energy storage systems for high-voltage monitoring:

1、Current monitoring accuracy within 0.5%, updated once in 1~10ms;

2、Bus voltage monitoring function: accuracy requirement: ±0.5%;

3, support relay sticking diagnosis function;

4、Support insulation detection function;

5、Support shunt temperature detection function;

Product advantages:

- 0.1% calibration-free accuracy (including reference, PGA and ADC error);

- G ohm level high resistance input (regardless of whether the PGA Bypass)

- Supports single power supply to complete positive and negative current acquisition (PGA Bypass mode, providing up to 4x gain);

- 16-bit resolution, 6 acquisition channels;

- Fastest 3.7kSPS conversion speed;

- Integrated low temperature drift reference, can be output to stimulate the sensor;

- Integration of two IDACs can be used to measure thermistor / RTD / thermocouple, and provide diagnostic function of temperature measurement disconnection;
