Apparatus for heating a vehicle cabin
First Claim
1. A vehicle including a cabin and trunk, the vehicle comprising:
- a high voltage fraction battery;
an electric motor powered by the traction battery;
a charger connected to the traction battery for converting alternating current (AC) to high voltage direct current (DC) to charge the traction battery when the charger is plugged into an alternating current (AC) power supply;
a forced air system including a first air duct providing flow communication between the trunk and the charger, a second air duct providing flow communication between the charger and the inside of the cabin, and a fan arrangement; and
the forced air system being arranged such that when operating in a first mode, air flows from the outside of the cabin through the first air duct, removes heat from the charger, and flows to the inside of the cabin through the second air duct, and when operating in the second mode, air flows from the inside of the cabin through the second air duct, removes heat from the charger, and flows to the outside of the cabin through the first air duct.

Abstract
A vehicle includes a cabin, a high voltage traction battery, an electric motor powered by the traction battery, and a charger connected to the traction battery. The charger converts alternating current (AC) to high voltage direct current (DC) to charge the traction battery when the charger is plugged into an alternating current (AC) power supply. A forced air system includes an air inlet duct, a first air outlet duct directing exhaust air to the outside of the cabin, a second air outlet duct directing exhaust air to the inside of the cabin, a fan, and a valve for controlling air flow through the first and second air outlet ducts. The forced air system is arranged such that forced air flows through the air inlet duct, removes heat from the charger, and flows through at least one of the first and second air outlet ducts to assist with vehicle preconditioning.
