Not So Sure
While batteries do not tolerate very fast recharging rates very well especially Li based systems its not clear if the fault is with Tesla, the charger or both. Chargers should be limiting the charge the put into a car anyway as Li batteries are notorious for not tolerating an overly fast charge. There are not enough details supplied about the chargers themselves to know. Though is not to say there isn't a fault on the Tesla monitoring and charging systems at the same time. If it is Tesla, it is also not clear whether the problem is fundamentally a battery problem or something else. Government Motors issued a warning the Chevy Dolts could catch fire due to a faulty battery.
