Re: AC Type 2 chargers - Understanding different combinations

the standard has 3A steps, between 6A and 32A, though I suspect most cars resolution is down to 1A or lower

a few members have at home stations that track solar use, so it's likely very granular indeed

Re: AC Type 2 chargers - Understanding different combinations

Unless I am miss-understanding something - which is highly likely ;) - there is not much point having a public 11kW charger, at it will reduce most cars to charging at 3.6kW or less, apart from the odd 3 phase capable cars? Most of the current generation cars have 3-phase chargers, capable of at le...

Re: AC Type 2 chargers - Understanding different combinations

it usually goes like this: car plugs in car reads current limit from the charge station car asks charge station to turn on car draws current up to the current limit if the car draws more than the current limit, charge station shuts down. so a car with a single phase charger plugging into a 16A 11kw ...

Re: 4kVA Inverter for 230VAC off a 350VDC battery?

it would still need pre-charging This is true of grid tie inverters too solar panels are nominally current sources, so their short circuit current is only little bit more than their maximum power point current. batteries are nominally voltage sources, so their short circuit current is several orders...

Re: Welp, ran out of charge for the first time

you are right 131v isn't empty. be aware though that the 110v lower limit is whilst riding, the pack voltage recovers some when it's sitting at rest. you won't ever see less than 115v or so after a ride due to this I use a TC charger with the enable function. The main improvement with the old EV Pow...

Re: Single phase charging

I did some charge testing last night. All values are reported by the car, though I did have my clamp meter inside the charge station to do a sanity check on values. The 3-phase 6A charging looked interesting, I might have to redo that measurement - it looks like the car was actually exporting power ...

Re: Welp, ran out of charge for the first time

yeah, that's normal in that your battery is full. what's happened is the battery is down on capacity. the full scale of the fuel guage (at least on the old nimh firmware) is 30Ah. you likely only have 20Ah of capacity the weakest and strongest cells must be pretty close to each other in both capacit...

Re: Vectrix acceleration and throttle problem.

That's certainly weird doing a motor calibration may help (it's easy to do and there's no harm in doing it) turn ignition off. lift rear wheel off the ground (a car jack usually does the trick) to get the mc to calibrate, you have to simultaneously hold the throttle at full, have the left brake on a...

Re: Making home EV ready

I'm not sure I understand the issue. The car battery is double insulated just the same as the panels on the roof are. The cars own motor controller output swings from +400v to -400v, so the insulation would be designed to handle that kind of switching. Coincidentally the both grid tie Inverters I us...

Re: Testing a traction pack before using

for things with a thermostat, be aware that switching dc is much harder on the contacts than switching ac. Might be better to use a bar heater that rarely switches, rather than a kettle that switches often

Goodwe make a single phase inverter that goes down to 80vdc input, and also supports export limiting.

all grid tie inverters can handle an unimpeded supply

I used a vintage PVE2500, but there are more modern inverters that will work down to 100v

The zoe topology has always used the motor inverter and motor windings to act as a charger. There is a version on Europe that has been available for about 5 years that can do 44kw recharge, though you're right, none here in Australia. The zoe motor and inverter are 44kw continuous rated as is, so ye...

Re: Fast charging infrastructure - forward-looking overview

I like the Tasmanian ones in the ocean :D

given the falling cost of powerful onboard chargers, and the poor reliability of stationary DC fast chargers, I suspect by the time there's significant build out, only the "old" cars being made now would use them
