Abstract
A hybrid electric vehicle includes an internal combustion engine, a traction battery, and a hybrid electric powertrain. A compact, portable, off board service jump-start device provides direct current (DC) power at a proper voltage and current to recharge the traction battery. The device includes a power supply with a high voltage output for providing the DC power. The device further includes a communication interface for receiving commands to control the recharging of the traction battery. The power supply recharges the traction battery in accordance with the received commands. Advantageously, this provides a compact, portable, off board service jump-start device that provides a controlled recharging of the traction battery of the hybrid electric vehicle and allows charging of the traction battery without the need for charging circuits on the vehicle.
