New LG Chem on-board chargers up to 11 kW

LG Chem on-board chargers

LG Chem offers complete and easy solutions for automakers that want to electrify their cars. The company not only produces batteries for electric cars, but also motors, inverters and now on-board chargers.

In Europe, 3-phase on-board chargers will soon become standard and LG Chem acknowledges it by making the 11 kW variant available from the start. While it’s a shame that a compact 22 kW variant isn’t already available, there’s always the possibility of using two 11 kW chargers in parallel to reach 22 kW.


• Rated 3.3 kW, 6.6 kW, 11kW
• High-efficiency (95% at maximum)
• Highly reliable and energy-efficient system
• Wide Out Voltage Range


I really think that powerful on-board chargers are very important, since the DC-fast chargers are very scarse. With decent charging capabilities, electric cars wouldn’t need to carry extremely heavy batteries everywhere – that by increasing the car’s weight, decrease safety (by decreasing acceleration and increasing stopping distance) and efficiency.

If an electric car has a 22 kW on-board charger and is able to charge up to 100 kW at DC-fast chargers, a 40-50 kWh battery would be more than enough for most drivers don’t you think?

My interest in electric transportation is mostly political. I’m tired of coups and wars for oil. My expectation is that the adoption of electric transportation will be a factor for peace and democracy all over the world.

    Do you think it can work as a single phase 7kW charger?

    • Pedro Lima says:

      I would be surprising if it doesn’t work at 11 kW (three-phase) and 7,3 kW (single-phase), just like the one inside the BMW i3 (94 Ah).

      • Pedro Lima says:

        Yes, the European BMW i3 (94 Ah) can be charged at 11 kW in 3-phase or 7,3 kW in single-phase (2 power supplies in parallel).

      • Lars says:

        Pedro: Are you sure that you can charge a BMW i3 with 11kW three phase, doesn’t the i3 only support one phase with 32 A?

      • Lars says:

        What about the newer VW e-Golf, does it also support three phase charging?

      • Pedro Lima says:

        No, the Volkswagen e-Golf doesn’t support 3-phase charging.

      • Pajda says:

        facelifted VW e-Golf MY2018 actually uses a two-phase 7.2 kW onboard charger in EU, so it charge 2x 16 A when connected to the three-phase socket.

  2. tolou says:

    Tesla didn’t have a 22kW charger either. It was 2 parallell 11kW chargers. Simple as that.

  3. Francesc says: in going to use 11kw charger for its sion car. 11kw is nice but i prefer 22kw and 40kw from Zoe …

    • Lars says:

      Francesc: Only the old Renault Zoe support 43 kW AC charging, the newer Zoe with 41 kWh battery only charges with 22 kW. Yes, 22 kW is nice, but with the Zoe the problem is that it only charges with 22 kW and not any faster. If the car supports fast DC charging I think that 11 kW AC charging would be enough.

  4. Tom Houlden says:

    I’ve seen my 500e brake regen meter read as high as 64kW, & I read somewhere that THAT charging system could be used as a high-capacity onboard charger, with no need for a separate onboard charger at all. I don’t know how this would apply to 3-phase or DC though. Any thoughts on that?

    I agree more on 50 kWh since only this battery size gives enough range at motorway speeds of 120 km/h and consumption at about 200 Wh/km.
    But @Tom Houlden, using the motor as a charger is a bad idea as ZOE has proven: it has only about 80% efficiency where “true” chargers are getting close to 95%.

  6. Lars says:

    I definitely think that three phase charging would be nice, but the question is what are the costs of such a charger? If it would have been an easy and cheap solution all cars sold in Europe would probably have it. With the cars getting bigger batteries they also need faster chargers to keep the option of recharging the car at home over night. It might also decrease the need for fast charging and by that increase the availability of fast charger for those who need them.

  7. Magnus H says:

    The EVs from European manufacturers are mostly 3-phase, but in the US and Japan 3-phase isn’t common at all.

      In series:
      – Renault Zoe
      (- Tesla, e.g. Model S (older ones 11kW in series and 22kW as option, today 16.5kW in series without any option concerning this))

      As option:
      – BMW i3 94Ah (IIRC in a package together with CCS)
      – smart ED

      Not available:
      – Renault Kangoo Z.E.
      – Renault Master Z.E.
      – BMW i3 60Ah
      – VW e-up!
      – VW e-Golf (2017 model but not 2014 model: 2 phase 16A oder 1 phase 32A)
      – Opel Ampera-e
      – Mitsubishi Electric Vehicle / Peugeot iOn / Citroen C-Zero



      • Lars says:

        You can probably add the Mercedes B-Electric, I think it could too charge with three phases.
        I would however not call the Opel Ampera-e European, it is a Chevy Bolt with Opel badge and that is the reason why it will not be sold anymore now that Opel is part of PSA.
