Abstract
In accordance with a first aspect of the present disclosure, a battery system is provided for use in a vehicle, comprising: a plurality of battery modules; a controller operatively coupled to the battery modules; a plurality of secure elements, wherein each of said battery modules contains at least one of said secure elements and wherein the controller contains at least one of said secure elements, and wherein said secure elements are configured to perform one or more authentication operations by executing a cryptographic algorithm. In accordance with a second aspect of the present disclosure, a corresponding method of configuring a battery system is conceived.
Claims20
A battery system for use in a vehicle, the battery system comprising:
- a plurality of battery modules, each battery module including a battery module controller (BMC) and one or more batteries coupled to the BMC;
- a controller including a battery management system (BMS) microcontroller unit (MCU) coupled to the plurality of battery modules;
- and
- a plurality of secure elements, each secure element including a memory device configured to store at least one of a cryptographic key and a cryptographic certificate;
- wherein each of the plurality of battery modules includes at least one of the secure elements coupled to the BMC;
- wherein the controller includes contains at least one of the plurality of said secure elements coupled to the BMS MCU;
- and
- wherein each of the BMS MCU and the BMC is configured to use a corresponding one of the plurality of secure elements to perform one or more authentication operations by executing a cryptographic algorithm to determine whether one or more battery modules of the plurality of battery modules has been tampered with or includes a counterfeit battery.
A method of configuring a battery system for use in a vehicle, comprising:
- providing the battery system with a plurality of battery modules, each battery module including a battery module controller (BMC) and one or more batteries coupled to the BMC;
- providing the battery system with a controller including a battery management system (BMS) microcontroller unit (MCU) coupled to the plurality of battery modules;
- providing the battery system with a plurality of secure elements, each secure element including a memory device configured to store at least one of a cryptographic key and a cryptographic certificate, wherein each of the plurality of battery modules includes at least one of the plurality of secure elements coupled to the BMC, wherein the controller includes at least one of the plurality of secure elements coupled to the BMS MCU, and wherein each of the BMS MCU and the BMC is configured to use a corresponding one of the plurality of secure elements to perform one or more authentication operations by executing a cryptographic algorithm;
- and
- determining that one or more battery modules of the plurality of battery modules has been tampered with or includes a counterfeit battery by performing the one or more authentication operations.
