Electric vehicle charging via grid and engine
A vehicle includes an engine, a traction battery, a generator coupled to the engine and battery, and a controller. The controller may be configured to, in response to a current flowing from a battery charge station to the battery being less than a maximum charge current, a selection of a fast charge mode, and a temperature of the engine being less than a predetermined temperature, operate the engine to generate a supplemental current to charge the battery.
1. A vehicle comprising:
an engine;
a traction battery; and
a controller configured to,
responsive to battery charge current from a battery charge station being less than a maximum charge current while the vehicle is parked and in fast charge mode, operate the engine to generate current to increase a charge rate of the battery, and
responsive to a signal indicative of a future route expected to traverse a green zone, inhibit operation of the engine.
2. The vehicle of claim 1 , wherein the controller is further configured to inhibit operation of the engine responsive to a signal indicative of a temperature of the engine exceeding a predetermined temperature.
3. The vehicle of claim 1 , wherein the controller is further configured to activate a cooling fan for the engine when the engine is rotating.
4. The vehicle of claim 1 , wherein the controller is further configured to, responsive to a temperature of the engine being greater than a predetermined temperature, activate a cooling fan at a speed greater than a standard speed.
5. The vehicle of claim 1 , wherein the controller is further configured to inhibit operation of the engine responsive to a signal indicative of a level of carbon monoxide in an area proximate to the vehicle being greater than a predetermined concentration.
6. The vehicle of claim 1 , wherein the controller is further configured to inhibit operation of the engine responsive to a signal indicative of a vehicle location being indoors.
7. The vehicle of claim 1 , wherein the controller is further configured to inhibit operation of the engine responsive to a charge duration defined by a difference in an expected start time of the future route and a current time being less than a time to charge the battery with the charge current.
8. The vehicle of claim 1 , wherein the battery charge station is an inductive charge station.
9. A powertrain control module for a hybrid vehicle comprising:
a controller configured to,
responsive to selection of a fast charge mode and flow of electric charge from a battery charge station to a traction battery, operate an engine to drive a generator to generate current to increase a rate of charge of the battery, and
responsive to a signal indicative of a future route expected to traverse a green zone, inhibit operation of the engine.
10. The module of claim 9 , wherein the controller is further configured to inhibit operation of the engine responsive to a signal indicative of a temperature of the engine exceeding a predetermined temperature.
11. The module of claim 9 , wherein the controller is further configured to inhibit operation of the engine responsive to a signal indicative of a vehicle location being indoors.
12. The module of claim 9 , wherein the controller is further configured to inhibit operation of the engine responsive to a charge duration defined by a difference in an expected start time of the future route and a current time being less than a time to charge the battery with the charge current.
13. The module of claim 9 , wherein the battery charge station is an inductive charge station.
14. A method to supplement current from a battery charge station comprising:
while a traction battery is receiving current from a charge station, operating an engine to drive a generator electrically coupled with a traction battery to generate a supplemental current to increase a charge rate of the battery; and
inhibiting operation of the engine responsive to a signal indicative of a future route expected to traverse a green zone.
15. The method of claim 14 further including inhibiting operation of the engine responsive to a signal indicative of a temperature of the engine exceeding a predetermined temperature.
16. The method of claim 15 , wherein the battery charge station is an inductive charge station.
17. The method of claim 14 further including inhibiting operation of the engine responsive to a charge duration defined by a difference in an expected start time and a current time being less than a time to charge the battery with the charge current.
