Abstract

A system utilizes vehicle location, direction of travel, battery status, destination, and other data to provide control instruction and information to a plug-in hybrid electric vehicle, electric vehicle, or user.

Claims

1. A method comprising:

a) acquire vehicle current location;

b) acquire battery status;

c) calculate distance to depletion according to said battery status;

d) utilizing said vehicle current location and said distance to depletion to search for charge stations within range;

e) determine if number of charge stations within range is smaller than a predetermined number; and

,

f) alert user if said number of charge stations within range is smaller than said predetermined number.

4. A method as defined in claim 1 further comprising:

a) acquire direction of travel; and

,

b) subtract number of charge stations that deviates from the said direction of travel from the said number of charge stations within range.

5. A method as defined in claim 1 wherein said charge station includes battery swap station if the vehicle utilizing said method as defined in claim 1 in a type of vehicle that utilizes battery swap station.

2. A method comprising:

a) acquire charge location;

b) acquire current vehicle location;

c) acquire battery level;

d) calculate electricity needed to travel from said current vehicle location to said charge location;

e) determine if said battery level is higher than the said electricity needed to travel from said current vehicle location to said charge location; and

,

f) instructs the vehicle to enter electric mode if said battery level is higher than the said electricity needed to travel from said current vehicle location to said charge location.

6. A method as defined in claim 2 further comprising recording said current vehicle location as a charge location when user instructs.

3. A method comprising:

a) acquire destination;

b) acquire current vehicle location;

c) acquire shipping list;

d) acquire battery level;

e) calculate stop-time and destination according to said shipping list;

f) calculate amount of electricity can be charged within said stop-time;

g) calculate electricity needed to go from current vehicle location to said destination;

h) determine if the sum of said battery level and said electricity can be charged within said stop-time less said electricity needed to go from current vehicle location to said destination is in excess of total battery capacity; and

,

i) instructs the vehicle to enter electric mode if said sum of said battery level and said electricity can be charged within said stop-time less said electricity needed to go from current vehicle location to said destination is in excess of total battery capacity.
