Anyone using CHAdeMO ?
« on: November 16, 2013, 09:36:29 AM »

Have any Zero riders bought the CHAdeMO option and if so what is that like to use?   What are the costs to recharge at a public station?

Here in Idaho there are no CHAdeMO stations to be found but I was looking on PlugShare and it looks like there are some great possibilities to tour on a Zero and QuickCharge along the Oregon coast.   Has anyone here done that?

Reportedly some chademo stations will not charge the Zeeros because it is relatively low voltage @ ~100v.

Damn! are you serious!?..

If it's true then it's really disapointing!

Anyway... no real need of Chademo... With  less than it cost for that option i built my own 1h ultracompact DC charger that can use the J1772 at 7kW and it work!

Guys; I'm talking with fast charger and inverter manufacturers here, about this issue too. I'm trying to get a 7kW fast bi-directional charger with a controller that allows you to buy and sell the energy in the battery.

Intriguingly by next year several products will be available.

Does someone knows the CHAdeMO standards?

I can't find data of the voltage only German Wiki says it will be in  300 to 600 Volt. 200A is mentioned often!

I fear the Systems will not regulate the voltage down to 50-100V what we would need.

protomech did I misunderstood you the charger are to low? or the charger can't go low.(sorry language gap)

I know SMA has developed a bi-directional charger for the charging stations "by government subvention"

I've never even seen a charging station, and wouldn't use one if it were available cause it isn't how I use my Zero. I know the range and if I need to go farther, I take a gas bike instead. The need for a quick charge has never come up. I would really hate to depend on something like that too. What if it doesn't work or someone else is using it? The 110 plug in my garage always works. If all gas stations had them, I would feel differently about it I'm sure, but to plan a trip around charging whether CHAdeMO or using some other plug would be a source of apprehension to me at...something that is totally unnecessary with 4 other bikes and a car that don't need to be charged.

The CHAdeMO spec supports up to 500V DC charging. But not all chargers (very unfortunately) support the full range of voltages.

Examples:

Will charge the Zeros
Aerovironment's Fleet 30 kW fleet DC charger is 100V to 500V, 100A maximum. (supports multiple protocols, and they have versions up to 250 kW!)
http://evsolutions.avinc.com/uploads/products/1_AV_EV30-FS_061110_fleet_dc.pdf
~1.2h charge time for ZF14.2

Nissan NSQC442E is 50V to 500V, 120A maximum.
http://evsolutions.avinc.com/uploads/products/Nissan%20DC%20FC%20sales%20sheet_092812_r3_v1.pdf
~1.0h charge time for ZF14.2


Will not charge the Zeros
EVTEC 10kW and 20kW are 250V to 500V DC output, 60A max.
http://www.evtec.ch/c5website/index.php/en/products/move_and_charge/

Blink Fast DC 60kW is 200V to 500V DC output, 200A max. (unfortunate, since these are the ones in Tennessee near me)

Wow you have really good information. Thanks

So it would be an idea to built a DC/DC for 300 to ~50V.

It would save weight  but still we would need a "charger".

Unfortunately DC is rare here but maybe DC-Charging becomes more because BMW starts its i3 today and they mention DC-Charging for 0,5h to 8ß% - Maybe only marketing strategy ::)

There are only 2 ChaDeMo staitons near me and they are both in NYC where they aren't very helpful (to me).  If they were along I-95 at all the rest stops it would allow me to take road trips in my car or motorcycle. 

Right now I have 4.5kW of charging capacity thanks to 2 Elcon chargers from Hollywood Electrics, but am thinking about asking Doctorbass to make one of his 7kW chargers for me since I use my bike for road trips.

If doc is doing this for you and you like to charge the bike while it is "OFF" I can help you how to do.
I like to spend the time while charging - shopping or exploring the spot!

Interesting ! So you know a command to activate the contactor with the bike OFF ?  But to " activate" something like i say, the sevcon need to be powered and to get that the DC-DC need to work too.. so... how do you figure that out?

I knoe that on every Zero there is two line that control teh cahrge and the throttle.. i touhgt about working on that to get the BMS and contactor  to be enable and to have the motorcycle OFF but i did not spent time on that... winter time will be just perfect for that as i will also upgrade for teh sevcon size 6 and add a ZF3 battery to it..

I have tapped in the Anderson at the on board charger. I use the Battery+ (red) and the charger control line (white) because I need both for my additional hardware that protect the system if the BMS shut the charger off.
Battery - is always available at the Sevcon (not switched) .

I don't need to start the BMS because my on board charger is doing this but if you use a 10-20KOhm resistor to 3.3V  at the white line the BMS will see it and pull it down to  ~1V now the BMS is aware someone is charging.

This is the first thing to know

The second thing is how to "open" the main relay like the bike is running.

I use a key-switch you can see on the photo at the right side under my seat.
I have cut the orange/red cable at pin 1 to the sevcon. it is the supply for the Sevcon.
In one position of the switch i connect the orange/red line as original (drive mode)
The center connection of the switch is running to the Sevcon the switching contact is the incoming cable (from MBB).
At the other contact of the switch I have connected the Battery + (tapped at the Anderson). If I switch the Key-switch to this position the Sevcon is powered on and the relay opens the high current path to the battery ;)
The rest of the bike is off! (of course the BMS is always on).
You can see the red Anderson connector for the charger and the  green and blue small Anderson in front of the red one there is the battery + and the white BMS control line to my charging box.
