Some rubber burning and new software for monitoring BMS

Summer has gone and I found eCagiva EV-conversion to be quite fun to drive. Maximum speed seems to be around 110-120 km/h, acceleration fairly good and overall driving experience very nice. I wish I had an bike with belt-drive though – then it would be totally silent …

Rubber burns quite easily now – it takes only under 7 kW power to get it slipping on asphalt.

During the autumn I have written an new software for monitoring Elithion Lithiummate Pro BMS system. It can read, display and log all the cell level data available. The software makes it easy to monitor the system while test-driving. Of course also workshop testing, balancing and charge-monitoring is very easy with this. Cell voltages, resistances and temperatures can be seen easily. Everything is logged to .txt-file and can be later viewed and graphed with the same software.

Here are some screenshots:

First, some graphs are drawn in real-time;

Everything is available also as a table – from there user can easily lookup each individual value easily.

And finally, there is this special display for those moments that you only want to see few key values with large fonts – such as when you are test-driving those few first drives with your new EV-conversion. Then it’s nice to have few most important readings in large friendly letters in your laptop screen – spelling “Don’t panic” for you :)
