Above 7 kW Charger for Gen 1 Prius Plug-in

mine charges in 90 minutes with L2, 2 1/2 hours or so at 120v.
not sure what is taking yours so long at 240v.

the charger is in the car, the best you can do is 90 minutes. i would investigate that first.
what do the manual and dealer say? maybe it is very low amperage?

if you want faster than 90, you're out of luck

 

Or get a Prime. It won't pull 7, but it does pull a little over 3.5 kW.

And, as @bisco said, the charger is in the car. A bigger charger would be quite a project if it's even possible.

 

I know how you feel. I do that a lot with things I want to do or buy. I call it champaign taste on a beer budget.

 

it may be that a wall box will put out more amps than your supplied evse, in which case it would charge faster, assuming you got the same charger as us.
but you would have to investigate. they are fairly inexpensive these days. agree on the baggage space, it was the only reason i didn't purchased one a few years ago when they were really cheap. what does toyota state for prime charging time over there?

 

I think you may be misunderstanding some aspects of this. As others have said, the charger is integrated into the car - the thing you use to connect the car to your normal domestic sockets is a portable EVSE, not a charger. The wall boxes you describe are also EVSEs or "charging points", they provide connectivity to charge but do not contain battery charging equipment. So any changes to these will not affect the car's built-in 2.2 kW charger.

The 2.2 hours doesn't sound right. The battery has about 3 kWh usable capacity, so at 2.2 kW and 240 V it should be able to charge in about 90 minutes (including some efficiency loss). Mine always reliably completes charging within 90 minutes whenever I time it (at 230 V).

 

I rarely check the charging time status on the dashboard so have no idea how accurate it is. But I can set a 90 countdown timer on my watch or phone when I start charging and it's always finished by then (at 230 V).

 

The Gen 1 PiP should charge in 2h20m on Level 1 (1.1 kWh) or 1h:10m on Level 2 (2.2 kWh). As others said, there is no way to go above 2.2 without some expensive experimentation... I have an L2 and use it all the time, and this estimation is accurate.

However, I have heard that some people have “converted” regular EVSE to allow higher voltage, apparently the EVSE hardware can supports it, if you have the necessary wiring in your garage. This would be the “cheapest” option.

Someone with more electrical expertise than me can perhaps elaborate.

 

The "level 1/level 2" stuff is a North American thing, we only have 230-250 V mains supply in Europe so only 2.2 kW charging.

I believe 90 minutes at 2.2 kW is typical.

 

That is a fair point and you are right, I was saying this from a North American point of view. Charge time could vary depending on voltage. Though honestly I did just learn that L1/L2 was only a North American thing, never gave it much thought.

 

Not just NA. Central and South America use the same voltage we do.
