Authenticating powertrain components of an electric vessel by a battery management controller

An apparatus for responding to detecting an error associated with one or more powertrain components of an electric vessel, the apparatus comprising:

• a battery pack disposed in the electric vessel;
• and
• a battery management controller coupled to the battery pack, the battery management controller configured to:
• monitor a control area network (CAN) bus for communication from one or more powertrain components of an electric vessel;
• determine whether an authentication message was received from a first component of the one or more powertrain components of the electric vessel;
• in response to determining that the authentication message was received from the first component, determine, based on the authentication message, whether the first component is genuine;
• and
• disable the electric vessel in response to determining, based on the authentication message, that the first component is not genuine.

A computer program product comprising:

• a set of one or more computer readable storage media;
• and
• computer program instructions, collectively stored in the set of one or more computer readable storage media, that when executed cause a processor to perform computer operations comprising:
• monitoring, by a battery management controller (BMC), a control area network (CAN) bus for communication from one or more powertrain components of an electric vessel;
• determining, by the BMC, whether an authentication message was received from a first component of the one or more powertrain components of the electric vessel;
• in response to determining that the authentication message was received from the first component, determining, by the BMC based on the authentication message, whether the first component is genuine;
• and
• disabling, by the BMC, the electric vessel in response to determining, based on the authentication message, that the first component is not genuine.
