Application: Temperature estimation device, temperature estimation method, program, and storage medium (Patent ID: US20230420758A1)
The patent filed by Honda Motor Co Ltd describes a temperature estimation device and method that estimates the temperature of a power device based on the temperature detected by a temperature detector in a detachable power storage device. The device includes an estimator that calculates the internal temperature of the power device housing based on the temperature of the power storage device, which is particularly useful when multiple power storage devices are present.
Furthermore, the device can estimate both internal and external temperatures of the power device, allowing for the detection of abnormal changes within the device. The method involves acquiring the power storage device temperature and using it to estimate the overall temperature of the power device. This innovative system can help in monitoring and managing the temperature of power devices effectively, ensuring optimal performance and safety.
