Delivering Fair Trade Certificates to West Frisian Businesses

  • By ivovandenbrink

Municipalities in the South West of Friesland stimulate local organizations to work on a more sustainable level. A great succes. Rebbl was asked to deliver Fair Trade Certificates in an appropriate manner: with the electric VW T2.

Do you have a special promotion that needs a special car? We’ve got electric old-timers for rent 🙂 Contact us.





Breaking: First time Fast Charging a DIY EV Conversion Car

  • By ivovandenbrink

We did it! We solved the puzzle. In the past few months we’ve had intensive contact with professionals from Orion, to implement the communication protocol for DC fast charging for DIY EV Conversions! Today we succeeded, and charged the electric oldtimer VW T2 at the Leeuwarden Station from Fastned with roughly 30kW/h.



High Quality EV on a Budget: Upgrade Original Peugeot 106 with Lithium Batteries

  • By ivovandenbrink

Would you like to drive a high quality electric car, but don’t want to spend a fortune? Here’s your solution: buy yourself an original electric Peugeot or Citroen from the beginning of this millennium, and give it a Rebbl upgrade with a brand-new Lithium Batterypack. This is what Jos van der Veen did, to get himself a green car for daily commuting, shopping and functioning as a taxi for his kids, on a budget.

In this video Jos explains:

  • how he got the car
  • how he did the upgrade
  • what materials he used
  • the specs of the upgrade kit
  • and the performance of the car after the upgrade

First ride in the oldtimer Citroen HY Streetfood wagon! Lekkeretrek: your sustainable one-off unique top of the bill electric van is almost ready to start selling 🙂



Calculating the optimal EV conversion kit for an Oldtimer Citroen HY Streetfood Wagon in the Low Countries

  • By ivovandenbrink

A few years ago, some crazy businessman asked us: ‘What electric drivetrain would you put in my restored oldtimer HY bus? It’s for selling honest streetfood!’ He kept coming back and was serious after all. So we started our calculations. This is our challenge:

  • the bus should do 100km range in every situation (frost, wind, rain, whatever) at 70-80km/hr max.
  • the wagon will be driving in The Netherlands, flat country, no regen. breaking necessary
  • the weight of a full street food wagon including the conversion will be 2200kg,  as a consequence a standard keyway shaft will not be strong enough for this application
  • there will be more HY conversions coming from this customer, continuity is an important factor
  • the HY drivers are probably not technicians, the bus has to be very reliable
  • the budget for the conversion has to be realistic: not low budget but not carte blanche either


Batteries and BMS
For a 2200kg car to do 100km on one charge even in bad weather, we would need 35kWh of batteries. We suggested 60 cells of Calb CA180ah (adding up to about 190V together) with an Orion BMS here. The Calbs have a minimum loss of capacity in winter and the Orion BMS is the only DIY system that supports DC fast charging (Chademo). For the future this could be an interesting option.


AC or DC
Then there is the choice between AC and DC, which is often made emotional instead of rational. AC seems more sophisticated, because most systems support regenerative breaking and have a better temperature control. It is appealing to modernize an oldtimer into the 21st century with an AC drivetrain. But it tends to be more expensive so we had to be rational. We compared a few possible setups:

1. Siemens AC motor – Azure Dynamics Controller
A Siemens AC motor in combination with an Azure controller would do the job just fine. The Siemens motor has a tooth splined shaft as a standard, which is the preferred driving shaft coupler, given the weight of this van. Both the motor and the controller have great automotive quality, we’re a fan. Aftersales is a big problem though, because there are only a few sets left from the bankruptcy. Doing a series of the HY bus would be a problem. Getting into the Azure controller and programming it to the right settings is a real pain, so not a pro in this discussion. This combination is now for sale at around €6.500, including Rebbl’s EMC certification which is necessary in Europe.

2. Emrax 268 AC PM motor – Unitek Bamocar D3 controller
An Emrax motor with a Unitek Bamocar controller would be an awesome solution. The Unitek controller is already EMC certified, the question is whether this will be accepted in combination with the Emrax motor. The Emrax motor is very promising because of it’s power and very small size (20kg), but according to the website ‘first customers are part of a fieldtest’. That might not be a problem for a DIY conversionist and we can’t wait to start experimenting with it, but for an entrepreneur selling streetfood on a daily basis this is might be a bit to early. The Emrax does not have a tooth splined shaft, so this has to be engineered as a special option. The heavy van really needs a sturdy coupler. The combination will cost at least €10.000, which is about 80% more than the solution we finally choose for.

3. Double HPEV AC motor – 2 Curtis controllers
The HPEV AC Motor and Curtis controller do great in smaller cars with a small to medium range. For the streetfood wagon there is the possibility of a twin HPEV setup in combination with two Curtis controllers, to give it enough power and enough voltage intake. Both are thoroughly tested and reliable. Also aftersales is great on these products, as is programming and finetuning settings. Drawback is the budget, our customer would need a minimum of €12.000 for this. Another drawback is the shaft, which is not tooth splined. This has to be engineered as a special option. This set is available including Rebbl’s EMC certification for the Curtis 144V/500A controller in a HPEV 51 or 75 set up.

4. Kostov Alpha DC motor – EVNetics Soliton1 controller
The Kostov Alpha 11” aircooled DC motor and the Soliton1 from EVNetics is a combination that can do the job on the DC side. The Soliton1 has an wide battery voltage inputrange of 9-340V DC and can deliver 1000A to the motor. Experience and aftersales on both products is good, and programming the controller is easy. Because the Kostov Alpha is well cooled it has a continuous power rating of 50kW, which is the best weight/power ration. This DC motor also has the necessary tooth splined shaft as a standard option available. This set is an investment of €5.750 including the Rebbl’s necessary EMC package.

We came to the conclusion that the quality/price ratio of the DC set would be highest for our customer, and so was our advice. We configured a kit that will serve as a model for future HY conversions from the same client, and other clients living in flat countries like The Netherlands. This includes the tooth splined shaft and coupler. But if you have the same plans in the mountains of Switzerland for example, your optimal kit will be quite different.

We did some amazing conversion projects together with universities and schools the past two years. We worked with Hanze Racing Division, Friesche Poort, HAN, Hanzehogeschool Groningen, Drenthe College, Satakunta, Flensburg University, Technicka University and Queens University Belfast. Teaching students is great, they want to participate in the electric revolution and really appreciate hands-on experience. Are you a teacher, or do you know a teacher, who would like to start a conversion project in Europe? We can help! Contact for more info.



Electric Citroën HY Street-food Wagon for Lekkeretrek

  • By ivovandenbrink

In january we will start converting an oldtimer Citroën HY to electric, in our new workshop in Drachten. The old bus will be restored body-off, converted to electric and then converted again: to a snack-wagon full of honest and delicious street-food. There will be several of these in the Netherlands. Take a look at this great initiative: Lekkeretrek. The bus will have a range of about 140km at 80km/hr and can be fully charged in 6-7hrs.

The bus will be converted with a DC motor-controller setup:


The clean HY body, ready for new paint


A special Kostov 11″ Alpha 250V mounted on the existing gearbox of the Citroen HY


Tooth splined shaft and torque adapter attached to the flywheel


Tooth splined shaft


Soliton 1 and Calb Lithium batteries

Awesome Ascona electric conversion

  • By ivovandenbrink

Take a look at this awesome Ascona conversion from one of our Dutch clients. The way the battery cases are designed, the near perfect installation of components, they show an eye for perfection. The Ascona was converted with an EVNetics Soliton JR controller and a Kostov 10″ motor. The battery pack has 52 200Ah Thundersky cells, which generates a range of about 230km for this lightweight car.






Unique EV Conversion: FT Bonito

  • By ivovandenbrink

A conversion project is quite special, so most of you choose a special model to convert: old vans, sporty oldtimers- and youngtimers are definitely favorite. We are now working on a car so rare, there are only a few of them driving around: one in the Netherlands and probably two in Germany. It’s the FT Bonito Cabriolet, a car with a VW Bug chassis and a plastic body that was inspired by the legendary Ford GT40. The Bonito can be converted with VW Bug components, and we will work on some general improvements as well. We can’t wait to drive it!
