eCagiva got new batteries and wow – the performance is bit different… Now I can quite easily keep up in traffic and bypass cars. It seems to be quite fun bike to drive now
New batteries are Kokam 70 Ah pouch-cells and the bike has 22 pcs of them. In the first few test rides the raw electric peak-power was somewhere around 14 kW when measured from the battery. A bit of dissapointment was that both motor and the controller heat up very quickly. I think there must be some sort of parameter to tweak in the motor controller (Sigmadrive/DMC 450A/80V 865L). Or I must provide additional cooling for them somehow.
Here is the first driving video with the new batteries:
I have also made an GPS-logger for testing my conversions. It logs current, voltage and GPS position & speed. All data gets written to the microSD-card as an TXT-file. I’m converting that file to the Google Earth for viewing – here’s quick screenshot of rendering the latest log in Google Earth;
I’ll tell more about the EVLogger in another post.
