I freely admit this is a pedantic point, but it's extraordinarily doubtful that any road car reaches 2000 ignitions per second (the threshold for "thousands").

In a 4-stroke engine each cylinder ignites once every two revolutions, so even a 12-cylinder engine wouldn't reach 2000 ignitions per second until 20,000 RPM.

A more typical case - say, a 6 cylinder engine hitting the redline at 7,000RPM is experiencing 350 ignitions per second - so, hundreds rather than thousands.

Thanks.

So batteries on cars is analogous to cars? I mean, could be. Maybe the EV battery is just like a gasoline tank, but something suggests that there are important differences.
