Battery maker A123 has said that batteries they had supplied to Fisker Automotive for their Karma range-extended luxury sedans might have wrongly aligned hose clamps for the cooling system, which could cause coolant to leak and cause electrical short circuit.
The problem will be affecting only cars less than 50 in number, as only 50 of them were delivered. Fisker Karma, a plug-in hybrid luxury sports sedan, after missing its initial late 2009 launch and going through re-schedules several times, had the first deliveries happen in the U.S. during late July 2011. Delivery to retail customers began in November 2011.
In December 2011, the pricing in the US for the car was $102,000 for the basic model and US$116,000 for the high-end model. The Karma is technically a series hybrid, driven by a pair of electric motors totaling 403hp that get their power from a 22 kWh lithium ion battery supplied by A123 Systems, or a 175 kW generator spun by an efficient, 2.2L gasoline engine.
The Karma’s two 201 brake horsepower (204 PS) motors produces 1,300 Newton meters (960 ft-lb) of torque, more than the Bugatti Veyron at 1,250 Nm (920 ft-lb). The Karma features a 125 mph (201 km/h) top speed and is capable of reaching 60 mph (97 km/h) from a standstill in 5.8 seconds.
A123 Systems develops and manufactures advanced lithium-ion batteries and battery systems for the transportation, electric grid and commercial markets. We guess the battery problem will soon be fixed by the battery manufacturers themselves.
