Test charging stop for large EV’s, busses, trucks, mohos.

While the en-route charging shown in the video is great.... The real benefit will be having the charging station at the destination loading dock to charge where the truck is already stopped to unload. Especially for fleet vehicles such as grocery stores. Will increase the incentive to get solar up on the store roof too.

I will say I know nothing about EVs other than I like the idea. That said many times in my life I have seen a battery that was fully charged hooked to a mostly discharged one with large cables and in a very short time the voltage in the discharged battery make a big jump up.
Now to go into theory, or really show my ignorance. Would it be possible to build a stationary battery bank, with say twice the capacity of the battery of the EV, and such that the fully charged voltage was 10% higher than full charge on EV? Then let solar panels on the roof charge that battery. The EV, pulls in with a low battery. Large cables, or better buss bars, join the batteries. Kick in a relay, wouldn't that charge the EV to full charge in a short time? If the EV was to set overnight, the cables could be smaller, charge slower.

Yes however the cables would have to be immense and the batteries would charge/discharge faster than optimum for long life. Still best to have a controlled charging cycle at the correct maximum. Using the existing down time of the truck in effect takes no extra time. If the truck makes nine 20 minute stops in the day to unload that is three hours of charging and no time lost in the schedule.
