Compute the power consumption of an EV powertrain in a certain state.
The model assumes that the driver recuperates as much energy as possible, meaning that he perfectly employs the mechanical brakes such that only what lies beyond the motor's capabilities is dissipated. If the new state is invalid, that is the demanded acceleration exceeds what the electric motor can manage or the power loss map is not defined for a given point, the torque and/or power are capped to the motor's limits or the power loss is set to zero.
