A short report about our last testing session ⚡🏁
Testruns were done with two of the three battery modules installed. One old version module with 18650 cells (1.44 kWh), one of the newer generation with 21700 cells and clamped cell connections (1.73 kWh). The new battery generation showed a significant reduction of heat build-up. After 20 min of riding the old battery was up to 47°C, the new generation still at 29°C. The line amps were limited to 300A total.
Our AXF500S axial flux hub motor stayed absolutely cool throughout all testing with surface temperature of the Rotor never exceeding 40°C. Current settings for the motor were 950A and 300A for regen braking respectively.
Of course testing was done at rather low ambient temperatures of ~10-12°C. Higher temperature testing will continue in summer with our newest and final generation motor and batteries.
One problem that keeps coming up, though, is that we still use 3D prints for most of the fairings. Consequently the front fender broke on one of the larger jumps and got completely obliterated, he rear fender started cracking too, eventually. For this, however, we are currently working on a lasting solution which required us to add another building to our workshop... more info on that soon.
So as always: Stay tuned, ride safe and thanks for reading through all this! ✌
