The battery controllers themselves sometimes proved very vulnerable,
lacking radiated immunity, but they always failed by disabling the
battery; no dying controller ever forced the cells into a conflagration.
But that is critically dependent on the detailed design of the
controller. Once a lack of immunity exists, there are limitless
possibilities (including simultaneous multiple disturbances) of
something switching ON in error rather than switching OFF in error. In
fact, switching ON is, in principle, more likely, as any sufficiently
large high-frequency disturbance presented to a bipolar base circuit
WILL turn on the device: turn-off requires a more complex scenario.
