Abstract: Methods, systems, apparatuses, and computer program products for using a secure wireless protocol within a wireless battery management system are disclosed. In a particular embodiment, a first wireless component of the BMS determines, based on a freshness value counter, a first freshness value. The first wireless component generates a message body comprising the first freshness value and a data payload. In this embodiment, the first wireless component uses a first session key shared with a second wireless component of the BMS, to encrypt the message body and generate a message authentication code based on the encrypted message body and the first session key. The first wireless component transmits to the second wireless component, a message that includes the encrypted message body and the message authentication tag.

Abstract: In a particular embodiment, functional safety in a battery management system includes a network controller of a battery management system (BMS) receiving from a module monitoring system (MMS) of the BMS, a message that includes a first set of data type blocks. In this embodiment, the network controller determines for the first set of data type blocks, a block sequence order that indicates a position of each data type block within the message. The network controller determines whether the message conforms with a predetermined block sequence protocol. In response to determining that the message does not conform with a predetermined block sequence protocol, the network controller determines that data within the message is stale.

Abstract: Methods, apparatuses, systems, devices, and non-transitory for resolving a failure in communication within a wireless battery management system (BMS) of a vehicle are disclosed. In a particular embodiment, a wireless network controller (WNC) of a wireless BMS determines that there is a failure in communication between the WNC and one or more module measurement systems (MMS). The WNC also determines a background radio frequency (RF) power level of a communication channel between the WNC and the one or more MMS and based on the determined background RF power level, selects one or more actions to perform in an attempt to correct the failure in communication between the WNC and the one or more MMS. In this particular embodiment, the WNC performs the selected one or more actions in an attempt to correct the failure in communication.
