Is there a need for 8S BMS for an eBike?
Why do I ask? I have designed a 8S Solar BMS for my off-grid house.
It is fully programmable so it can work with any type of Lithium cells (ex LiFePO4,LiCoO2....)
It has an LCD so you can monitor all cell voltages, current, power, energy, remaining battery capacity and much more.
I know by looking here that most of you use way higher voltage 12 - 16 or even more cells. Why?
I think the average human can deliver less than 200W sustained power so why will you need a motor that dose much more than that.
Will not a 24V 500W motor be more than enough?
This Solar BMS can support up to 80A discharge that is 2000W way more than sufficient (at least I think so
) for an eBike and can be programed lower like 64A or 32A
It was not specifically designed for ebike as I mentioned before but will it work for an ebike ? and if so what changes will be necessary?
I can already see one problem and that is the LCD is on the unit and probably mounted close to battery so you can not see that on the bike.
Maybe I can use the serial port to send data to an external display.
Anyway here is a 3D render of my BMS but I also have a beta already working.
