  • Offline mutual authentication for battery swapping
    Patent number: 11362521
    Abstract: An offline mutual authentication method for battery swapping includes communicating a first authentication request to a battery by a computing device associated with a battery charger. A first authentication response is communicated to the computing device. The first authentication response is verified, and a first challenge request is communicated to the battery. A first challenge response is communicated to the computing device. The first challenge response is verified, and a battery authentication status is communicated to the battery. A second authentication request is communicated to the computing device. A second authentication response is communicated to the battery. The second authentication response is verified, and a second challenge request is communicated to the computing device. A second challenge response is communicated to the battery. The second challenge response is verified, and a charger authentication status is communicated by the battery to the computing device.
