I actually came across the reason for this today researching something else but I don't have the links at the moment. Supposedly the J1772 Yazaki connector and cable initially failed UL testing at 32 amps but passed when tested at 30 amps.leafme wrote:The L2 EVSE in my garage is capable of passing 30a (listing maximum) and is fed by a 240v, 40a branch circuit (technically, the EVSE could be rated as high at 32a on a 40a branch circuit but it's not for some reason).
Yes I would like to have a UK cord. I would just install a 14-50P and start charging.garygid wrote:The UK does not have a "Level 1" (120v) charging cord.
They get what we would call a "Level 2" (near 240v) charging cord.
Voltage in the UK is usually 240v (or 230v +/- 10%), I believe.
The UK and US vehicles both are J1772-2010 compliant, so the on-board charger will be auto-ranging. As soon as I get my car, I'll be checking out the included Level 1 EVSE to see if the PWM signal generator is auto-ranging as well. If so, I should be able to have instant 240 volt, 12 amp charging!LTLFTcomposite wrote:Has it been confirmed that the L1 charging cord differs between US and UK versions? Any change the charger in the car is voltage sensing?
Surely it must be able to automatically adjust to multiple voltages. How else could you use the same port for L1 and L2 EVSEs?garygid wrote:No, the EVSE does not "signal" the voltage, but the LEAF's charger COULD measure the AC voltage, IF it wanted/was designed to do so.
