Method for measuring current and temperature in motor car, involves switching power supply for measuring temperature, and measuring another measuring voltage falling at measuring resistor and temperature-dependent resistor
The method involves connecting a measuring resistor (110) for measuring battery current (IB) and a temperature-dependent resistor (120) for measuring temperature (T) in a motor car. The temperature-dependent resistor is connected with a switchable power supply (130), which measures the battery current. Measuring voltage at the measuring resistor is measured. The switchable power supply is switched on for measuring the temperature. Another measuring voltage falling at the two resistors is measured. A limiting resistor (140) is switched in parallel to the temperature-dependent resistor. An independent claim is also included for a measuring circuit for measuring current and temperature in a motor car.
