I'm making my own thread about this because it doesn't necessarily just apply to the Tongsheng Motor, but is relevant here.
Could you use the temperature sensor from the BMS, and have it wired directly to the motor, so that the BMS is actually measuring the heat of the motor and not the battery pack itself?
Keep in mind this would only work in low current applications where this is absolutely no concern about the battery pack overheating (Tongsheng TSDZ2 is a good candidate because they usually draw a max of 18A).
The Bluetooth Programmable BMS's (JDB among others) have a thermal programming feature where you can choose which temperature the BMS cuts the current flow leaving the battery ... so it could be programmed to a desired temperature.
Obviously a few measures would have to be put in place like extending the wires of the temp sensor and its added resistance, making sure that it is actually properly calibrated, and making sure that the BMS can effectively cut the current at the desired temperature level.
With that idea in mind the TSDZ2 could have throttle operation and temp rollback together.
And other motors that have built in controller's without thermal protection could benefit from it as well.
The idea could essentially work for any motor that you're able to glue a temperature probe onto to measure the heat inside the motor (again as long as the battery pack doesn't need the temp probe itself -> low current applications are what come to mind).
Just a thought? Would love to hear some feedback. Might be stupid but that's okay. Only 1 way to learn right!
