First Claim
Patent Images
1. An automotive drive system comprising:
- an electric motor;
a battery coupled to the electric motor;
a magnetic field generator configured to subject the battery to a predetermined magnetic field such that the battery and the magnetic field generator jointly create a resultant magnetic field;
a magnetically responsive component configured to generate an electromagnetic response to the resultant magnetic field; and
a processor in operable communication with the magnetically responsive component and configured to;
detect the electromagnetic response; and
determine a state of charge of the battery based on the electromagnetic response.

Abstract
Methods and systems are provided for determining a state of charge of a battery. The battery is subjected to a predetermined magnetic field such that the battery and the predetermined magnetic field jointly create a resultant magnetic field. The resultant magnetic field is sensed. The state of charge of the battery is determined based on the resultant magnetic field.
