Sevcon Data to Dashboard

A short video of getting Sevcon tpdo’s to my digital dash. https://youtu.be/8lbicY0C2n0

More work still to do but so far pleased with this first incarnation.

Re: Dashboard suggestions

Just finished working out how to get a micro controller to read my Sevcon size 6 TPDO Data. I have the dvt software so I know the scaling factors and this data can be ported to a digital display.

I will create a new thread to document the process soon.

Re: Sevcon Gen4 CAN messages

The addresses are the COB ID’s of each TPDO, each PDO contains objects such as battery voltage, motor current etc. You will need to know what object(s) are in each PDO then you can work out the decimal values from the hex values and apply any scaling to get readable data. Each TPDO can hold 8 bytes ...

Re: Sevcon Gen4 CAN messages

I am trying to do the same, use the CAN data to drive a display from my Size 6. I haven’t been able to initialise CAN yet so work in progress. I may be able to help with the CAN data you have posted. I will check those values in my DVT tomorrow and see if I can decipher them.

Re: YZF600R Thundercat EV

I now have a Gen 4 Size 6 in the bike at 78V nominal and 30kW peak power gives me a peak current of 375A. The Sevcon has calculated this to be 57Nm of torque. The motor is good for 90Nm and 425A rms at 100V. I am working in improving the cooling so I can throw more amps in and still chasing some Nis...

Re: First post, electric motorcycle build.

That is a good choice for your first ev build. At 20S4P what capacity of battery cell will you be using? When you source your controller get one that will allow you to expand the performance of your bike as and when you can afford to. My mistake was buying the wrong Kelly Controller and limiting mys...

I am thinking of using the front and rear sections of a Sprint ST 1050 with the trellis frame sandwiched in the middle. There are plenty of these parts on ebay. What do you think?

Re: Bernel's new electric motorcycle build

Here is frame rev002 following Chris Jones' comments. I must add I am not a motorcycle frame builder and I am taking my cues from existing bikes of all types. This bike is not going to be for racing it will be a commuter/weekend warrior bike.

Re: Adventures in programming a Sevcon Gen4 Size4

No more issues, the end throttle voltage was too low. External LED is working, just need to buy some more LED bulbs and find somewhere to mount it.


I am now just tweaking settings then I will work on the drive profiles.
