Hello guys!
First and foremost, you have an awesome community here, been following you for some time now and now I finally have something to post.
Secondly, you'll have to excuse my lack of proper/correct terminology or knowledge of this topic, I’ve haven't been a part of this field long enough, nor do I have experience, to completely understand everything, in general, I do when it comes to your basic stuff, but not so much in some particularities when it comes to correlation of certain components between each other. Although I don't have complete knowledge in this area of expertise, I do have a very, very high level of enthusiasm and love towards it, which keeps me going and which enables me to pick up everything relatively quickly (partially also thanks to my IT background).
I got my hands on a Swiss Huttles go-kart (one of the rental models), which I’m going to completely strip down everything ICE related and convert into an EV.
I would really like to build it ground up using quality and well known/tested/trusted components/brands, so I don’t have to go back and redo something, or even worse if something goes wrong because of a "low quality" component.
Anyway, I have a few concerns which I would like to go through and if someone could help me out, It would be a great help!
1. I’m all good in terms of my motor choice (probably something from Lynch LEM200 series or something beefier from Motenergy, 72V system bottom line), but what are my options in terms of motor controllers being controlled in a particular manner, or to be more precise receiving “live inputs” and making split-second changes via additional MCU with set of different sensors?
For example, can I take an Alltrax DXE motor controller, or something else which is able to do this in terms of other motors controllers, hook it up to let’s say an Arduino, or other even more advanced MCU / SoC’s, which has different sensors hooked up to it and which is programmed to alter the motor controller configuration in real-time when sensor picks something up?
2. On that note, what’s a good quality option for such MCU / SoC which is also “open” / programmable enough to do something like that?
3. What should I look at in terms of communication channels (what’s flexible/open enough) in such a scenario, between the MCU to the motor controller that is? CAN, UART, something else?
4. What are my options in terms of good quality BMS (I’m planning to build my own 72V 21700 battery pack, I need around 300A in peak) which can communicate with the motor controller itself and be flexible in terms of how it works in relation, for example, to regeneration cut off and other advanced features, or is that controlled in a different way? Is that a thing or is / can that be controlled just from the BMS / charger side of things? I’ve found a lot of what seems to be a well reputable BMS, but I’m not sure which one could be “up to that”.
5. I want to avoid onboard charger solution (because, weight reduction, bro), so I’m trying to find a good quality “brick” converter charger (probably gonna go for an XLR connection), but I honestly can’t find anything expect Cycle Satiator or Luna Cycle. Is something like YZPOWER a good alternative or should I avoid that? If there isn’t anything worthy in terms of that, maybe I should stick with onboard solutions, something like Delta-Q or other alternatives?
6. My drive axle is currently belt driven, should I stick with it, or should I go for the chain, and could you explain why? Is this a pros and cons thing, or a certain situation requires a certain solution?
That should be it... For now!
Thanks!
