Battery Transparent Learn Cycle
Transparent Learn Cycle (TLC) is a periodic operation that calculates the charge that is remaining in the battery to ensure that there
is sucient energy. The operation runs automatically, and causes no impact to the system or controller performance. The controller
automatically performs TLC on the battery to calibrate and gauge its charge capacity once every 90 days. The operation can be
performed manually, if required.
