Electric Vehicle Patent Classification

Electric propulsion classifies in B60L: traction motors, regenerative braking, on-board charging and the electric side of the drivetrain.

The mechanical integration, mounting of propulsion units, hybrid arrangements, cooling, sits in B60K. The battery cells themselves classify in H01M on the battery side.
