The specifications in the above look totally bogus!
The fact they don't use proper capitalization in the physical units
might be expected, but either the specs were "developed" by an
innumerate person, or the thing is highly misleading, or both.
The specs say it can be recharged using a household electric power
socket. If you click on "SPECIFICATION" in the above web page, you
can see they define the "Power outlet" to be 220 V, 10 A.
The specs state or imply the e6 uses about 18 kWh per 100 km, has a
range of 400 km, and can "quick charge" to 50 percent of capacity in
10 minutes. This means it charges to 36 kWh in 1/6 of an hour, so
charges at a rate of 216 kW. This is a charging current of (216 kW)/
(220 V) = 982 A. That is 98 times the current capacity they specify
for a home power socket. At 10 amps the battery can not even be
charged to 50% capacity in 10 hours, according to the specs.
Now, it might actually be possible to charge in 10 minutes, going
from some kind of home energy storage system to the car battery, but
the connector that can carry 982 A at 220 V would be different in the
extreme from a home electric power socket. There is no mention for
the need to buy a home energy storage and charging unit. If such is
required the specs are still highly misleading, at least to me.
Another alternative might be to swap batteries at home, which could
be done in 10 minutes, but no mention is made of this either.
Further, swapping out a 72 kWh battery pack sounds like a daunting
task for the typical car owner - especially one without a garage. I
can find no way to make any sense of this ad.
