Re: [EVDL] CHAdeMO rapid charging station in > Portland

500V x 200A =3D 100kW =

So a relatively large 35kWh pack could =

theoretically be charged from empty to full
in about 20 mins.
Since it is not likely that you can sustain
this charge level once the batteries come up
in charge above 80-85%, and you will usually
not pull into the charge spot with completely
empty pack, it is more likely that you will =

charge for 10-15 mins to put in some 20-25kWh
and leave with about 80% charge.

Any topping up will not require such a large
charger, as the heat production in the pack
will limit the power that you can supply without
damaging the cells during topping up.

It's 500 volts DC at 200 amps. The charger itself will provide no real regu=
lation. Some of the small pins on the connector are CAN bus communications,=
this is what will provide the control to the off board quick charger.

So in order to use one you will need a CAN enabled BMS so this will make in=
tegration in to conversions difficult if you don't have a relatively sophis=
ticated BMS. The other problem is that no SAE standard instruction set for =
CAN communications has been set to my knowledge, which is a major hindrance=
to the industry right now in my opinion and a question I've ran in to more=
than once.

Still 50KW recharge capability. I'll take it! I am on the list to get a Lea=
f, I should be able to order by Thursday and being part of the EV Project I=
have to get the fast charge port and they have many planned for the Phoeni=
x market so in about a year I'll let you know how it works if I buy the car=
. They are warning that quick charging often will hurt the pack life, espec=
ially in the heat, there is a battery temperature gauge on the dash so they=
are making us aware of this. I plan on leaving an evaporative cooler runni=
ng in my garage where the car is parked during the summer and possibly just=
using the 120vac cord if I can to slow charge it. =
