    Car Battery management sensor;

    Hi,
    I want to implement the battery management system for the car, which sensor is suitable to get the voltage, current & temperature and remaining things like over charge, over voltage, over current & over temperature protection etc.....

    please suggest a sensor which is suitable for car battery management system, i am going to use 6 cell LiFePo4 battery. That sensor should have a feature to communicate with micro controller via. simple communication protocol.

    Thanks & Regards,
    Chandu.Kurapati.

    Re: Car Battery management sensor;

    proposal:

    ACS712 hall effect sensor to measure the DC current , with galvanic insulation
    range 0-5A , 0-20A

    ADC12 bits like MCP3304 4CH 12 bits for :
    -Amps (analog signal from ACS712)
    -Battery voltage
    -temperature LM35DZ (0-50°C) 0 -500mV
    use classic I2C protocole

    or maybe a specialized device .. see LTC family power management & other supplier
