Several investigations continue into fires involving lithium-ion batteries involved in automotive applications. That includes a fire that destroyed a Fisker Karma plug-in hybrid parked in a Texas garage last year, and another involving Fiskers that were caught in flood waters during Superstorm Sandy last autumn. Several other battery based vehicles also caught fire in a storage lot at a port outside Newark, New Jersey, and it appears salt water short-circuited their electric systems.
The Chevrolet Volt plug-in hybrid also became a target of investigators in 2011 when the National Highway Traffic Safety Administration revealed a battery pack caught fire weeks after a Volt was crash tested. A second battery later started smoking after it was tested.
Eventually, investigators concluded the Volt problem was largely the result of NHTSA’s testing procedures. Nonetheless, General Motors subsequently made significant changes to further reduce the likelihood of problems following a crash.
Separately, Fisker announced changes to its battery pack design following a fire linked to a cooling fan system. And the California-based start-up was forced to order a recall of early versions of the Karma when a manufacturing defect was discovered by battery supplier A123.
Fisker has struggled with sales significantly lagging initial expectations. Chevy, meanwhile, suffered a short-term decline in sales after the initial report of the fire at a NHTSA test center. Demand soon rebounded, however. Sales of the plug-in more than tripled last year compared to 2011 levels – but still came to barely half of GM’s initial 45,000 target for the U.S. market.
“No questions, these kinds of headlines (surrounding the Boeing batteries) are not going to help battery vehicle sales,” contends analyst Phillippi and others.
