The smart charger allows a user to switch the charge process of e-bike lithium batteries off earlier: at 40% (winter storage - degradation is minimal), 60% - 70% - 80% (save lifetime and decrease driving range) and 100%.
Switching off takes place based on the voltages that correspond with the 4 "save" positions. As this is not 100% accurate, the switching points are recalculated by measuring the charge energy.
I have done hundreds of projects in the cross-fields of power electronics (charging - DC/DC conversion), embedded software and data communication. My long term partner retired so I am looking for a new free-lancer to take over.
Proven experience will be a condition.
The attached documentation explains the details. The preference for PIC is because the hardware prototype is available, but when there is a good reason to change this is acceptable.
