"Jump-Charging" a 1e

[garygid]

Thought: A 1h generator could "jump-charge" a 1e
if the right connections were designed into both.

If designed in, and then an appropriate "jumper" cable was
available as an accessory, it might not even cost very much.

"Jump-Charge" would be a nifty connection / feature to have.

Unlike ICE, I am afraid EV cannot be jumped charge. In order to transfer electricity from one battery to the next, the source battery must have higher potential (voltage) than the battery being charge. The source battery must have a least 12% higher voltage to charge a depleted battery. For example, to charge a 12.0V battery, your charger must deliver from 14.5V to 15.5V, regardless of the current capability from the source. FYI, the depleted battery only shows a slight drop in voltage. Also, the higher the current the source or charger can deliver, the faster the depleted battery get charged.

If I was going on long trips in a Typ-1e, I'd probably bring along a small portable generator -- just enough power for a 120V/15A socket, to keep the generator as small and light as possible (I've seen as low as 30 pounds). While the Aptera should be light enough to push fairly easily, it'd save me the trouble of having to pester farm owners for a charge in an emergency ;) Of course, that always remains an option.

This is what I have in mind for a portable charger. My neighbor has one, he said it is very reliable. When he runs it, I hardly know that it is on sometimes. Of course at higher load, it can be very loud.

The Jump-Charge mode would NOT be like an ICE with jumper
cables directly from one battery to another.

Rather, it would be a special mode designed into the Aptera.

For example, one idea (maybe not the best) would be for the
"Source" vehicle to configure itself to produce power, maybe
even something like 120 AC (or other more optimal power)
on a special internal connector (maybe even a standard AC
female socket). Then, a simple extension cord could be used
to charge the other "Thirsty" vehicle. Cool, yes?

Or, if the Source 1h had an internal 12v 150 amp (a LOT of amps)
connection, a standard 12v DC to 110v AC inverter could be used:
for example, this (http://alltoolssupplyinc.com/home_files/pob1500w.html).

If the internal connection was 24v DC at 75 amps, an inverter like
this (http://www.batterystuff.com/inverters/S150024.html) could be used, but this one is rather expensive.

If one had a special inverter designed to work from the "200v DC"
internal battery, then that might be better. But, that is basically
what the motor drive is, a DC to AC "inverter", so I am
thinking that, with the proper control settings, the existing
motor-control electronics could be programmed to do this job.

Further, when the 1h's generator is going, it probably produces
AC voltage already, and maybe it could be configured to produce
120 volts directly. The generator output could always be wired
to the special internal "rescue-1e" socket, just rarely used.

As an additional benefit, it would be a quite nice feature if this
vehicle had a 1500 watt "110 AC" inverter built in (with a standard
duplex socket, and a 20 amp circuit breaker) to use to power normal
consumer electronics.

Blended strawberry margaritas at the beach, yum!
Oops, no drinking and driving, oh well ...

For charging the 1e faster, other configurations of the 1h's
generator and the 1e's "rescue" input would be better.
