Re: [RE-wrenches] Electric car chargers
I recently installed a tesla charger, 100 amps at 240v, grid tied customer.

Re: [RE-wrenches] Electric car chargers
Michael: Are you sure about this? Tesla is the one company that had data on their web site and they claim a maximum of 70 amps: http://www.teslamotors.com/roadster/charging/high-power-wall-connector If you are correct, I will need to upgrade the 100 amp service I am planning. Let me know, please. If you have a specification sheet or photo of an equipment plaque, that would be appreciated.

Re: [RE-wrenches] Electric car chargers
William, Yes, I'm sure, installed it myself. It is the newest charger, for their new sedan, I watched as the owner tested it up to 80 amps as displayed on the interior touch screen, beautiful car! The owner promised me a test ride.

Re: [RE-wrenches] Electric car chargers
William, I found this on Wikipedia: Level Original definition[195]Coulomb Technologies' definition[196] Connectors Level 1 AC energy to the vehicle's on-board charger; from the most common U.S. grounded household receptacle, commonly referred to as a 120 volt outlet. 120 V AC; 16 A (= 1.92 kW) SAE J1772 (16.8 kW), NEMA 5-15 Level 2 AC energy to the vehicle's on-board charger;208 - 240 volt, single phase. The maximum current specified is 32 amps (continuous) with a branch circuit breaker rated at 40 amps. Maximum continuous input power is specified as 7.68 kW (= 240V x 32A*). 208-240 V AC; 12 A - 80 A (= 2.5 - 19.2 kW) SAE J1772 (16.8 kW), IEC 62196 (44 kW), Magne Charge (Obsolete), Avcon, IEC 60309 16 A (3.8 kW) IEC 62198-2 Type2 same as VDE-AR-E 2623-2-2, also known as the Mennekes connector (43.5 kW)IEC 62198-2 Type3 also known as Scame Level 3 DC energy from an off-board charger; there is no minimum energy requirement but the maximum current specified is 400 amps and 240 kW continuous power supplied. very high voltages (300-600 V DC); very high currents (hundreds of Amperes) Magne Charge (Obsolete) CHΛdeMO (62.5 kW), SAE J1772 Combo, IEC 62196 Mennekes Combo .* or potentially 208V x 37A, out of the strict specification but within circuit breaker and connector/cable power limits. Alternatively, this voltage would impose a lower power rating of 6.7 kW at 32A. Is this what you're looking for? My Nissan Leaf came with a Level 1 adapter cord to plug into any standard 120v outlet. I installed a Level 2 charger in my garage, 240v/30 amp. The car also has a Level 3 charging port that I've used several times at public Level 3 charging stations. Randy Brooks Brooks Solar, Inc.
