Tesla downplays 'brick' threat
Tesla came out with a statement Wednesday regarding a report about Tesla's turning to battery-dead "bricks."
Tesla Motors Inc. on Wednesday downplayed the threat that batteries in its electric cars could easily be rendered useless and in need of costly repair.
The company's response comes after blogger Michael DeGusta posted a long piece on Tuesday saying that several Tesla Roadsters that were left without a charge for long periods of time saw their batteries rendered into useless "bricks." The only repair, he said, is to replace the battery at a cost of about $40,000, nearly half the cost of the $100,000 sports car.
He estimated that leaving a fully charged Tesla Roadster unplugged for 11 weeks would destroy the battery, less time if it isn't fully charged.
Tesla (NASDAQ:TSLA) in the following prepared statement doesn't deny that this could happen but said it is unusual and there are many measures in place to prevent it:
"All automobiles require some level of owner care. For example, combustion vehicles require regular oil changes or the engine will be destroyed. Electric vehicles should be plugged in and charging when not in use for maximum performance. All batteries are subject to damage if the charge is kept at zero for long periods of time. However, Tesla avoids this problem in virtually all instances with numerous counter-measures. Tesla batteries can remain unplugged for weeks (even months), without reaching zero state of charge. Owners of Roadster 2.0 and all subsequent Tesla products can request that their vehicle alert Tesla if SOC falls to a low level. All Tesla vehicles emit various visual and audible warnings if the battery pack falls below 5 percent SOC. Tesla provides extensive maintenance recommendations as part of the customer experience."
