Hi, thanks a lot for your reply
I thought I mentionned it but my scooter is already a m365 PRO, that's why i'm a bit disappointed
I have several questions that seem to be unsolvable, everybody have a different version
- How is the regen braking activated ? Do I have to press the brake handle to activate it ? Or is it passive like for example I'm riding downhill, I release everything (accelerator and brake handle), does it regenerate with the resistance I feel in the front wheel ?
- If the brake handle activates regen, then it means there is a sensor in it somewhere, so what if I remove it ? Does it remove Kers ?
- If I disable Kers with a custom firmware by setting activation above 40km/h for example, will I still have the motor braking ? And if yes, will it generate energy ? So is it still dangerous for my controller ?
I'm scared of taking big slopes now, and I would like to be able to ride freely without worrying about it, I mean yes I understand that climbing big hills with heavy weight can be dangerous for the scooter but come on I broke my scooter TWICE on a downhill where the scooter has the less stress, gravity does everything !
Automatic KERS and brake lever braking and regenerating are separate things.
1) Regen braking, if you have not used any custom firmware, work automatically when you release the throttle, unless you are in cruise control mode, ofc. It will simply apply rolling resistance and work to slow you down, generating some little energy.
2) Yes, there is a magnet and a hall sensor in the brake lever. The magnet is in the moving part and the sensor is in the fixed part - you move the lever, the magnet moves away and the sensor does its thing. If you remove the magnet, it will be constantly braking (and have error when you turn the scoot off and on). To make it inoperable, you can permanently attach the magnet to the sensor and it will never register that you pulled the lever. I do not suggest this as the single disk brake is not that good.
It wouldnt remove KERS: KERS, as I said before, works automatically when you release the throttle
3) Kinda, not really, maybe a little bit. First of all, if you set KERS to 40, be sure to use firmware 1.3.8, because in 1.3.8 the motor wont shut down completely and will have like 15w of power sent to it, thus making the transition from free wheeling to accelerating or braking much smoother. In 1.4.+ the motor will completely shut down, but will also introduce strong jerking when transitioning.
When you set KERS to 40, it will automatically activate only when the scooter has passed 40km/h, which practically mean never. But it will still work when you press the brake lever slightly (and you have not messed with the lever or something). And I have also noticed some generation happening when driving down a bridge and pushing the throttle just a little bit, depending on the speed. I suppose it happens because the throttle is saying to the wheel to stay at, say, 10km/h, but gravity is trying to make it go faster so the extra energy from gravity is being generated into electricity and pushed in the battery. Or something like that.
