I'm having trouble getting hold of proper Coulomb/Distributor personnel.
Could you please ask them:
1] Does a Coulomb station include an internal "revenue meter" which LADWP will accept for billing ? (Avoiding an additional utility meter.)
2] What does such station cost ?
3] Can it be used in any residential application, not just public ?
4] Is that station being supplied to eTec for their EV project areas ?
I did talk to a representative of Coulomb. Here are the answers to these questions:
1. Yes, the Coulomb product for public use has a utility grade meter built into it. To date, no utility has agreed to use it on their networks. The utilities are still evaluating this, seeing how it would fit into their business plans and regulatory issues.
2. The first public station in a location would cost about $5600 not including installation. Second and subsequent stations in the same location would cost $4400-$4600.
3. They are working on a residential version that would have all the same capabilities including the utility grade meter but without the billing function. Not firm cost has been determined yet but it would be "considerably less" than the public station.
4. No, they are not supplying eTec or the EV project. They have their own separate federal DOE grant and are pursing the placement of public stations on their own, separate from EV project efforts.
The answer to my question to the representative about whether our condo complex that has retail in the front and retail/guest parking spaces would qualify to be a part of their grant for a public charging station was No because our parking garage is closed to the public from about midnight to 4 am and a stipulation of their grant is that the public stations be accessible to the public 24/7.
