if theres pics of this event, feel free to post them up.

if a car was struck by lightning, all its electrics would be history.

That is a pretty hard question to answer not knowing the extent of the damage. If the damage is not bodywork and is contained to the electronics then it totally depends on the replacement cost of the ECU etc.

cars can be struck by lightning with no damage at all.

Chances are there's a fair bit of electrical damage to the more sensitive parts (ECU, etc) but there is also a chance that it's blown a main fusable link and there's not much else wrong with it.
Most of the sensitive parts have a bit of protection on them.

Not for any reason I can imagine !

In fact it seems from googling that it is the 12V system that suffers in a lightning strike (ECU and CAN bus systems). Much the same systems in all vehicles.
The traction voltage/pack is so well shielded/insulated that the outside world (lightning included) is non the wiser.

Electric vehicles attracting lightning would be a real urban myth. Oil companies would like to spread that one !

Heh, let's see... assume a 25 kWh pack, so that's 25 * 3600 = 90 000 kJ or 90 x 10^6 joules. At 1.21 JW (I'll assume that's 1.21 * 10^9 W), that's a full charge in 74 * 10^-3 seconds, or 74 ms.

That's lightning fast!   Image

Actually, I'm not sure that lightning lasts that long. So you might have to hang around for it to strike twice   Image

Also, it may exceed 6C briefly... In fact, 74 ms is 2.1 x 10^-5 hours, so that's actually 48,600 C   Image

My old digital camera shooting movies at 15fps defn catches ~3 frames of lightning.
Even allowing last frame for flare you should get enough in one strike Image

So the short answer is NO but the long answer is YES.
