Abstract
Responsive to a powerline connection of a vehicle to electric vehicle supply equipment (EVSE), vehicle version information is received indicative of whether the vehicle requires software updates that are downloaded to a non-transitory storage. If so, the software updates are sent to the vehicle over the powerline connection. If not, the software updates are requested over a wide-area connection to a remote server to be cached in the storage for use in subsequent vehicle powerline connections.
Claims15
An electric vehicle supply equipment (EVSE) comprising:
- a non-transitory storage;
- and a processor programmed to
- responsive to a powerline connection of a vehicle to the EVSE, receive vehicle version information indicative of whether the vehicle requires software updates that are downloaded to the storage,
- if so, send the software updates to the vehicle over the powerline connection, and
- if not, request the software updates over a wide-area network to a remote server to be cached in the storage for use in subsequent vehicle powerline connections,
- wherein the vehicle version information is sent during an association procedure configured to allow EVSEs and vehicles to identify one another when a vehicle is connected.
3 more elements
A vehicle comprising:
- a processor programmed to responsive to vehicle association to electric vehicle supply equipment (EVSE) over a powerline connection to receive a first charge of a traction battery, send version information over the connection to cause the EVSE to download software updates to EVSE storage, the version information being sent during an association procedure configured to allow EVSEs and vehicles to identify one another when a vehicle is connected,
- reconnect to the EVSE to receive a second charge of the traction battery, and receive the software updates from the storage via the connection during the second charge.
A method comprising:
- responsive to a powerline connection of a vehicle to electric vehicle supply equipment (EVSE) for charging of the vehicle and receiving vehicle version information indicative of whether the vehicle requires software updates, the vehicle version information being sent during an association procedure configured to allow EVSEs and vehicles to identify one another when a vehicle is connected, requesting the software updates over a wide-area network to a remote server to be cached in a non-transitory storage of the EVSE for providing to vehicles during subsequent vehicle powerline connections.
