determine a new estimated battery charge level and then reset the BDI
to the new estimate. Unfortunately, this estimate is wrong — because
in fact no charge was actually put onto the battery.
6.d The Partial Charge Min parameter is designed prevent these false estimates.
Subtract the pre-wait BDI value (step 6.b) from the post-wait BDI value
(step 6.c), and use this as the lowest setting for Partial Charge Min. It is
recommended that you use a somewhat higher value in order to block
short charges, which are not an effective way of charging the battery. Do
not use 100% unless you want to disable the partial charge function.
Typically 30–50% is a reasonable compromise.
6.e Plug in the charger and complete the full charge.
Step 7. Rerun and Verify
This procedure will give good initial settings for the BDI algorithm. You should
test these settings under various conditions to verify that they provide an ac-
ceptable indication of the battery state of charge. The settings can be fine tuned
by repeating the entire procedure.
It is important to note that battery age and driving conditions (hilliness,
driving surface, weight of user) will all affect the accuracy of the BDI measure-
ment.
