摘要： Described herein is a device for autonomously monitoring a battery is provided. The device is integrated with the battery (e.g., by being electrically coupled to the battery). The device obtains measurement data by injecting electrical signals into the battery and measuring an electrical response of the battery. The device participates in an authentication protocol with a computing device to verify a unique identity of the device to the computing device. After performing the authentication protocol verifying the unique identity of the device, the device transmits battery data to the computer. Further, techniques for verifying the identity of the battery using measurement data obtained by the device are described herein. The techniques generate a battery signature using the measurement data that is then used to verify the identity of the battery. For example, the battery signature may be used to determine whether the battery is counterfeit or defective.

摘要： Low-cost time synchronization associated wireless Battery Management System (BMS) and a host controller are described herein. The time synchronization techniques described herein are low-cost because of the use of existing communicating lines without using adding additional dedicated lines or wires for synchronization. Moreover, the time synchronization techniques described herein may be implemented without complex circuitry.
