duty NEMA 14-50 adapter. This is the type of connector most often found on
electric ranges but also at RV parks across the country.
This adapter will connect the two phases of 240 vac service to the two blade
prongs of the charge port, and the neutral of the two phases to the ground pin.
The battery pack in the car is completely isolated from the frame of the car and
ground. So grounding the circuit accomplishes nothing in any event.
In this way, you can use the same charge port from either 120vac or 240vac
sources.
Your electrical box in your house or building assuredly has two 120vac phases
for 240vac. In almost all lighting and sockets in your house, you only use one
of the phases – typically half the circuits on one phase and the other half on
the other phase. But an
electrician can easily wire a
NEMA 14-50 range/oven
connector into your garage to
provide 240vac charging to
your car. The charge for this
varies based on how far he
has to run it, but is often
available at $200-$400 and
no special code provisions
beyond this are necessary. A
60AMP circuit breaker is
more than enough.
When connected to 240 vac
The 3kW charger will initially charge the 120vdc battery pack at about 24.5
amperes. You can observe this on the BMV600HS display using the I function.
This will continue until the pack voltage reaches 126.6 vdc. At that point, the
current will begin to decrease. If you leave it charge unattended, you can tell
that it has completed on your return if the I current indication is less than a
couple of amperes. The charger itself is totally silent and so the meter is the
only indication you will have that it is actually charging.
If you completely deplete the 162Ah in the pack, at 24 amperes it would reach
full charge in about six hours and 45 minutes.
If you use 120vac connections, this time could be doubled.
And so you readily see that the car charges faster from 240vac, and the actual
charge time is totally dependent on how many ampere-hours have been
removed from the pack by driving the car.
