Electric vehicle reserve charge authorization and distribution

A method for accessing battery reserve charge of an electric vehicle, the method comprising the steps of:

• providing a battery having a reserve charge portion for powering the electric vehicle only after an authorization signal is received, and a normal-use charge portion for powering the electric vehicle regardless of whether the authorization signal is received;
• setting, using a processor connected to the battery, a reserve charge level of the reserve charge portion;
• initiating, using the processor, a telematic link with a remote device;
• transmitting, using the telematic link, the reserve charge level from the processor to the remote device;
• transmitting, using the telematic link, a location of the electric vehicle from the processor to the remote device;
• authorizing, using the remote device, powering of the electric vehicle using at least a part of the reserve charge portion of the battery based on the received reserve charge level and the location of the electric vehicle;
• receiving, using the telematic link, an authorization signal at the processor from the remote device;
• and
• utilizing, using the processor, at least a part of the reserve charge portion of the battery to power the electric vehicle when or after the processor receives the authorization signal.

A system for accessing battery reserve charge of an electric vehicle comprising:

• a rechargeable battery coupled to the electric vehicle, the battery configured to have:
• a reserve charge portion for powering the electric vehicle only after an authorization signal is received, and
• a normal-use charge portion for powering the electric vehicle regardless of whether the authorization signal is received;
• a processor coupled to the battery and configured to:
• set a charge amount of the reserve charge portion that accounts for a loss of a maximum charge capacity of the battery, and
• determine a geographic location of the electric vehicle;
• and
• at least one antenna coupled to the processor, the at least one antenna configured to:
• transmit the charge amount of the reserve charge portion and the geographic location of the electric vehicle to a remote device,
• receive an authorization signal from the remote device for authorizing use of at least a part of the reserve charge portion of the battery to provide power to the electric vehicle, the authorization signal being based on the received charge amount of the reserve charge portion and the geographic location of the electric vehicle, and
• utilize at least a part of the reserve charge portion of the battery to power the electric vehicle when or after the processor receives the authorization signal.
