Power drain

The big ol’ resistor that straddles the two high voltage poles on the connector is problematic. Although it only lets a small amount of power bypass the connector it is enough to slowly drain the battry if left unatended. So I need to pop in battery isolator switch on the positive cable comming out of…

1st motion

Finally got the QS hub motor moving with temporary wiring. I encountered a couple of issues here and there but luckily I managed to reach out to a Mr. Powell in the US that has a leaf cell / Kelly controller set-up that is similar to my own and hey presto, the hub finally lives….

Wiring…

Okay, time to make a start on the cable loom for XJ600e, finally. Bit of a boring post but an important one because once all is sound with the wiring then finally the panel design can start with the assurement that the packaging for the powertrain is concrete. This means less changes to the final…

Isolator carriage v2 printed

I know I should be used to it by now (after all I see it happens all the time in University and in the design industry) but it still amazes me that I can print designs into reality that only exist on a computer. Anyway, I managed to push out a rough print overnight to…

Isolator carriage v2

Have made some changes to v1 design of the isolator carriage. A bit more cable management and some amendments to the BMS to ensure the charge input cables are orriended correctly, etc. Need to print the design to double check it maybe get some advise of the management of the cables. Currently the high and…

Isolator carriage v1

Having had some small issues with dimensional accuracy I have finally started to get some results on the bigger prints and I am finding new uses for the printer. Originally I planned to stick the BMS, charger, and precharger components onto a thin board with 3M double sided tape to isolate it from the batteries….

Brake lines

How long should the brake lines be? As long as a piece of string! Planning the final dimensions for the brake lines. Measurements have been taken with a cord. The factory lines at the front (1 x 310mm upper / 2 x 495mm lower) do not need to be changed. However the rear line is…

v3 Sketch surface update

Surfaces have been update for the xj600e. Using the sketchwork seen in a previous post CAS renders visualise the potential outcomes of using new riser bars instead of the Cafe racer clip-ons and how the change of design direction works in 3D with the current powertrain.

Sketches… v2 (out with the old)

More sketches… this time with a mince pie. It’s Christmas! Version 1 of the XJ600e used aesthetic features that would make it acceptable to the traditional rider. However, further research and dialogue with manufactures indicated that the new rapidly moving marketplace for 2020 preferred aesthetics that were more aggressive and ‘gadget-like’.
