Systems and Methods For Preheating Hybrid Vehicles

摘要

A method of preheating a hybrid vehicle including storing reserve coolant in an insulated reservoir fluidly coupled to a coolant circuit of an engine of the hybrid vehicle; powering a fluid pump fluidly coupled to the coolant circuit with a power source external to the hybrid vehicle; pumping line coolant through the coolant circuit with the fluid pump; powering a heater thermally coupled to the coolant circuit with the power source external to the hybrid vehicle; heating the line coolant with the heater as the line coolant is pumped through the coolant circuit to increase a temperature of the line coolant; and mixing the line coolant with the reserve coolant to accelerate preheating of at least the engine of the hybrid vehicle.

1. A method of preheating a hybrid vehicle, the method comprising:
storing reserve coolant in an insulated reservoir fluidly coupled to a coolant circuit of an engine of the hybrid vehicle, the reserve coolant having a temperature TR; powering, with a power source external to the hybrid vehicle, a fluid pump fluidly coupled to the coolant circuit; pumping line coolant through the coolant circuit with the fluid pump, the line coolant having a temperature TL that is less than or equal to the temperature TR of the reserve coolant; powering, with the power source external to the hybrid vehicle, a heater thermally coupled to the coolant circuit; heating the line coolant with the heater as the line coolant is pumped through the coolant circuit to increase a temperature of the line coolant; and mixing the line coolant with the reserve coolant to accelerate preheating of at least the engine of the hybrid vehicle.
