A system tracks and controls access for supplying electrical power for charging devices associated with a user. The system has a server and one or more outlets. The outlets are connected to electrical power and are configured to supply electrical power to the devices. Each of the outlets has a socket configured to supply electrical power to the devices. Each of the outlets is further configured to transmit credentials to the server for authorization to access the outlet. The server is configured to determine whether the user is authorized to access the outlet and to transmit authorization to the outlet. The outlet is further configured to start a session and provide electrical power to the one or more devices upon receiving authorization from the server. The outlet is further configured to transmit information regarding the parameters to the server during the session.

The present disclosure relates to a battery protection circuit module to which an authentication circuit unit is applied and a method of protecting an authentication circuit unit using the same, and more particularly, to a battery protection circuit module including a part arrangement design that is robust against external environment noise and a method of protecting an authentication circuit unit using the same. A battery protection circuit module to which an authentication circuit unit is applied may include an authentication circuit unit connected to an output stage of the battery protection circuit module and a protection device configured to protect the authentication circuit unit against external noise.

A charger management server manages compatibility between an external charger and a vehicle. The server includes an information acquisition unit that acquires charging status information on a status acquired when the external charger and the vehicle are connected to conduct charging, and a compatibility information generation unit that generates compatibility information on compatibility between the external charger and the vehicle based on the charging status information. The server also includes a charger management database storing the charging status information and the compatibility information. As the charging status information, the information acquisition unit acquires vehicle information on the vehicle, charger information on the external charger connected with the vehicle, and charging error information on a charging error caused between the external charger and the vehicle.

A method for mutual authentication between a host controller and a battery subsystem of an electronic device includes, at a battery controller, generating a battery-side authentication challenge, and transmitting the battery-side authentication challenge to the host controller. A host-side authentication challenge is received from the host controller. The host-side authentication challenge is signed with a private encryption key of the battery controller to generate a battery-side message digest. The battery-side message digest and a public encryption key of the battery controller are transmitted to the host controller as a battery-side signature pair. A host-side signature pair is received from the host controller. Based at least in part on the host-side signature pair, a battery-side validation result is output that specifies a battery-side validity state for the host controller.

A smart battery includes a battery and a measurement module coupled to measure electrical characteristics of the battery. The smart battery also includes processing logic and a communication interface configured to receive the electrical characteristics and transmit the electrical characteristics to a receiver.
