Electric, Speedy Charging Stations Have Problems Of Their Own

Granted, you may look at your car’s battery cooker and think “there’s no way that this can harm my electric’s batteries because the top voltage available is only 18 volts and today’s battery packs can handle this heat load. Would that be true? Instead, the way the failure of the quick-charger network station might happen is that the capacitors that help to set the voltage level fail due to the constant heating, cooling, and overstressing cycles.

Long Time Until It Happens, If It Happens

Granted, it shouldn’t happen for 300 or 400 periods, but given even a 10 percent device failure, the number of batteries that might fail on any given day is truly staggering. The reason for the battery failures is that once the capacitors and their associated diode packs go, nothing is keeping the high-inrush current from hitting the cars sitting on the network. So, you think the relatively low voltage will keep your batteries safe. The answer is this: it won’t.If your quick-charge network suddenly loses its protection, your car batteries will be cooked by the 25 or 30 amps at 18 volts rather quickly.

And, there’s another danger, fire. Today’s car batteries are a mix of lithium-ion and nickel-metal hydride each of which can burn when exposed to high currents and the attendant heat. So, let’s say you have a fast- charge network with a charging station that has gone and a car whose batteries are taking too much current, what do you think happens? You have a car that will burn; there is little question of it.
