Abstract
A transmission in combination with a temperature measurement device and a device exterior to the transmission. The transmission includes a rotatable housing which drives a wheel of a vehicle, a wireless transceiver in communication with a thermistor embedded within molding, a battery embedded within the molding, and the molding resides within the housing. The temperature measurement device resides in a wall of the rotatable housing and the rotatable housing includes an interior volume. The interior volume of the rotatable housing is partially filled with oil for lubrication of transmission components residing within the interior volume of the housing. The temperature measurement device is rotated through the oil and out of the oil within the rotating housing when the rotating housing is in motion. The wireless transceiver is in communication with the device exterior to the transmission and communicates a temperature measurement from the temperature sensor and battery state of charge information to the device exterior to the transmission.
