Roger Ormisher, director of Fisker global communications, told us that “the Karma’s battery only depletes to about 15% state of charge”
Similar to the Chevrolet Volt, the Karma uses a gas generator to help extend the vehicles electric range.
Tesla ran into some hot water when a customer left their Roadster discharged and unplugged for two months. When the customer tried to charge the car again, it wouldn’t take a charge. When the car was taken to Tesla for repairs, it was estimated to cost $40,000 to fix.
Fisker made sure to point out that its battery is “a different composition to that of Tesla’s meaning that it takes many months to fully discharge even if it is not plugged in.”
While that doesn’t mean the Karma is completely immune to ‘bricking’ it does offer some peace of mind to owners. We guess the Biebs can go on tour for a few months with his Karma unplugged, but we wouldn’t recommend it!
