Disclosed is a traction battery self-heating control method and a device. Acquiring a second temperature of a rotor at a current sampling time according to system parameters and a first temperature of the rotor at a previous sampling time, and estimating a third temperature of the rotor at a next sampling time according to the first temperature and the second temperature, and stopping the self-heating of the traction battery when the third temperature reaches a demagnetization temperature of the rotor. Whether to stop the self-heating of the traction battery is determined by estimating a rotor temperature under the self-heating condition, and comparing the rotor temperature with the demagnetization temperature of the rotor, and thus the self-heating control of the traction battery is realized.

A system includes a first printed circuit board (PCB), a temperature sensor, a switching circuit provided on the first PCB, and a controller. The temperature sensor is configured to measure temperature of at least an area of the first PCB.

The system is able to disrupt power much faster than conventional methods of power protection which may have a blind spot to certain areas of the first PCB, since these methods rely on power disruption when a maximum power is sensed.

Self-calibrating a humidity sensor of an integrated humidity and temperature sensor, using the integrated heating element, and the temperature and humidity sensors, of the device, together with a firmware-based control loop running on a controller. The controller actively calculates and monitors one or both sensor output, and the slopes of the sensor outputs, in real time, while the heating element is on, and compares one or both slopes to a pre-programmed threshold, while in a programmable control loop, to then capture the appropriate relative humidity offset to apply to the device during normal operation (with the integrated heating element switched off) for correcting the relative humidity output from the device. Any singularly mounted in-system device can be calibrated, independent of external references, for in-system calibration.
