Looooong time no see! Well, a lot of things happened in the meantime, sorry for not keeping you up to date. In April, the last works were completed and in May we had to present our work to the vehicle inspection guys to get a license plate and the official permission to cruise on the streets. Luckily the guys at the office were not very much interested in the whole electrification thing, so the check was completed in about half an hour. We just had to demonstrate things like working windshield wipers and correct speed display in the dashboard! Ah and there was this discussion about the motor power. It is a bit difficult with electric motors, because they have a nominal power and a peak power rating. The peak power is what they can deliver for a short time, e.g. up to maybe 30s, before the thermal limits are reached. As originally our van had 54kW, it was just allowed to get an increase of maximum 10%, which would be 59.4kW. The nominal power of the motor is 57kW which suits just fine. And because the original gearbox is said to be not very robust, we also limited the peak power of the drive to about this value.
One thing though is a bit a pity: The empty weight of the car increased to 2100kg due to the electrification. This means it is now only a 5 seater.
From then on I could go officially on test rides on the roads and make a lot of tuning of the control software. There were things to adjust like ramping of torque commands, sequence of turning on and off of the different devices when driving. But by far the most work was to setup the proper communication between charger and battery management. The big issue here was to figure out the best way the two devices should work with eachother. But with some trying and testing I found a well-working solution.
