Re: Nissan Ariya

the 2 seat pipstrel uses about the same amount of energy as a nissan leaf.

to be honest I really want to learn to fly, just so that I can fly down south on electricity, and not have to be bored in a car.

Re: Nissan Ariya

It’s strange that we are obsessed with cars that use much more energy as a house full of people. To be fair, cars have always used more energy than a house, they were just powered differently Though most of the energy used in a house is embodied in nature, rather than used at the house. https://the...

Re: Zoe off grid charging

so what happens when you charge with positioning lights on only?

when you go to charge normally, what happens when the battery reaches full before the car's fuel gauge?
Does the gauge reset to full? or does an error get thrown?

reviving an old thread here, but what blocking diodes do you guys use? on my setup I have 4s5p 175W 36Vmp, 5.5Amp setup. I had a 10A10 blocking diode on each string as I was direct connecting to a 144v nominal battery 10A10 diodes are normal silicon units, so 0.7v or 0.8v drop. At 5A, they're gettin...

Zoe R motor has a spare 400 V connector in the back where you can connect solar pannels directly to the battery , no inverters :) But you have to be careful, the car must be on or the positioning lights must be on, so that the car will not go to "sleep" and diskonnect's the main contactor, if that ...

Re: tractor conversion

An encoder is only needed it you want fine torque control. On a tractor you could probably get away with either speed control only, or course torque control that running open loop without an encoder would offer

Sorry why couldn't an industrial motor controller/inverter be used? couldn't one be be tricked into outputting 240Vac 50Hz. it would need an output inductor (field windings off an old induction motor maybe?), and also likely a minimum load it would be interesting to try out I have thought about usi...

Re: AC Type 2 chargers - Understanding different combinations

oops, quite right, there are a few cars that have higher single phase current limts so you could ask for 7.3 A say, and maybe get 7.28 A or 7.41 A due to tolerances in the components, measurement inaccuracies, and so on. I saw this on my zoe the other day when I was doing the charge testing. phase c...

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 ...

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.
