Chargers

Accelev Type 1, Type 2 & Tesla US 2-phase charger 5kW & 6kW

Accelev uses 3-phase connection to speed up charging of single phase cars (find your car in table below).

It is not a simple cable that controls charging, but it is a high-efficient AC/AC converter, that builds one „super-phase” from two normal AC phases. Such „super-phase” has slightly higher nominal voltage and dynamic voltage stabilization against load, enabling faster charging even in current limited cars. Accelev is portable, cables can be disconected.

For average European house, where 3-phase power is delivered, protection fuse is B16 (16A) or 20A. Usually higher power may be possible, for extra cost. So max charging speed may be 16A per one phase.

Advantage of 2-phase charger is simply visible. No overloading of phases while charging up to 6kW, fastest possible home charging without any special power delivery line. No high currents = no heat losses = high efficiency.

Available sets

  • Accelev 5kW – 20A/250V, max 11A per phase
  • Accelev 6kW – 24A/250V, max 13A per phase

Input: 16A 3-phase, 32A 3-phase

Output: Type 1 (J1772), Type 2 (Mennekes), Tesla US

Accelev EV and PHEV compatible cars along with charging capabilities

Table below consists of most of known EV and PHEV cars, number of phases and type of plug they use, max charging power theoretical (gross) and approximated real (net), and gain of speed, while using 2-phase Accelev EVSE instead of 16A aftermarket charging cable.

Colors represent:

Green – perfect gain for Accelev over other chargers

Pale green – good gain for Accelev over other chargers

Orange – not applicable or slower than direct EVSE connection.

In simple words: If you live in Europe, or other region where energy delivering for private separate properties bases on 3-phase 400V or similar system – green will mean “must have” – you will accelerate 2 or more times your charging (for Outlander PHEV there is a special trickery to accelerate charging more than the numbers show – see below to paragraph 4). Pale green – 20% acceleration, no phases overload, orange – no idea to use Accelev (no gain).
Red – incompatible.

The last column shows 3h charge with 16A EVSE as a time of same charge for Accelev – so you can see time savings (beside of other advantages like lower phase loads).
Time saving versus factory 10A charger is not presented (Accelev is 2-3 x faster than any factory 10A EVSE cable).

7. Questions and FAQ according to this text – tpirowski@vtechtuning.eu (in English please).

If you have any questions – no problem – ask me. I may answer in few days as I’m overloaded catching Elon Musk with his ideas ;)

Common FAQ are below – maybe you will find your question below?

What is the main advantage of Accelev over all other chargers?

It loads equally two phases. You do not need to have special, more expensive energy connection to your home. It charges with speed equal to 22-28A of ordinary charger within much lower current (amperes) limit per phase.

I have 440V 60Hz 3-phase power (USA) – can I use Accelev?

Yes, there is no problem to use it. It will load one phase by about half of end current.

Is voltage boost to 250V+ dangerous some way? I see this on Accelev screen.

No. It helps to pass more power without additional heating of charger and onboard charger. Also it reduces charging time and is one of advantages of Accelev over all other chargers. The nominal supply voltage is 230 V +10%/−6% (standard normative), so up to 253V it is absolutely normal. Most electric cars accept voltages up to 265V.

Why Outlander PHEV charges with Accelev only 3.6 kW, not 5 kW?

Speed (amperes) is controlled by on-board chargers. For PHEV it is 14A, for Leaf with single charger it is 16A (4.0 kW with Accelev), and with double charger – it will be 20A (5 kW). It is still 20% faster than any EVSE 1-phase cable due to voltage boost.

Is 24A from Accelev equal to 24A from ordinary charger?

No. It is equal to 28A from ordinary charger because of voltage boost. Literally you need 28A ordinary EVSE cable to have equal speed, except Outlander PHEV (see next question).

Accelev has a special charging procedure for Outlander PHEV. Why?

PHEV uses twice (at empty battery and at almost full battery) kind of pre-balancing. This means it stops charging (exactly charges with <0.2A) for about 25 minutes in total. This makes time of charging with any charger longer by these 25 minutes. Accelev reduces this time to about 2 min, increasing speed of charging from zero to full.

Is charging with speeds of 5 or 6 kW dangerous for battery?

No. All cars won’t suffer with that speed. During driving they are drained 10-30 x faster.

Why dual phase Accelev is not using 30A charging?

As most of 3-phase home grids in Europe have 16A protection per phase and about 14A permitted load, so using 11,5-13A from any of two phases is a good idea. We avoid overloading them.

Why don’t you offer 3-phase charger?

It will be available – we work on it. Also 2-phase Accelev owners would be able to buy extension module for 3-rd phase. It will be 8kW power in total (250V, 32A). So having 20A Accelev you will be able to expand it to 32A 3-phase in the future, when extension is ready. Same will be enabled for Accelev 6kW users (24A version) – then 36 A/250V will deliver 9 kW/h

Why Accelev 5kW takes 11,5A per phase and delivers 20A only? 11,5 + 11,5 = 23

It’s because voltage boost uses some more ampers, so they are not lost. 23A at 230V equals to 21A at 250V. Efficiency of energy conversion is about 95% so we have 20A, 250V at output.

So nothing is lost :)

Dynamic current control – how does it work?

Oh, this is simple – it monitors voltage. As voltage drop against load is a common known process, Accelev reduces charging speed within some limits, when it detects voltage drop at any phase. This means Accelev tries to avoid overloading phases, when you start something energy-consuming at same phase(s), that Accelev uses. Not perfect, but good to avoid fuses punch and blackout, when your wife starts their MegaWatt Rocket Hair Dryer while you charge your EV car to commute next day.

WARNING: GEEKS QUESTION: Do you use 250V Powercon Neutrik connectors?

No. We buy connectors that look very similar, but they have 500V 20A certification. Color of connector does not mean the same as colors in Neutrik connectors, as producer is different. You are safe, our connectors have proper certifications.

Surprisingly not only one invented circle. Also not only one Neutrik uses circle-round connectors.

Yeah.
