JimD Posted January 14, 2020 Report Share Posted January 14, 2020 I just bought a used cmax energi with around 37,000 miles. The first time I charged it i got 20 miles. Now I am lucky to get 12-13. I talked to a friend who has a fusion and he said maybe the battery is leaking. Any help with this would be helpful please. Plus how long is the warranty on the electric battery? thanks Quote Link to comment Share on other sites More sharing options...
ptjones Posted January 14, 2020 Report Share Posted January 14, 2020 Was it warmer out when you first got car? HVB range goes down with OT. Paul Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted January 14, 2020 Report Share Posted January 14, 2020 Jim D, you need to measure the kWh used from a full charge until drive mode switches from EV to Hybrid. That will give you an idea of your battery degradation from new. IIRC, a new HVB will should deliver around 5.5 kWh of EV only driving. MIles driven on a full charge is not the best measure of lost capacity. As soon as the forum administrator are able to merge the fordcmaxenegiforum into this forum, you should have many Energi owners that will help you. Where are you located? Battery leakage? - if meaning battery degradation, it occurs in Lithium Ion batteries as the batteries are used (cycled). So, one can operate the HVB pack to mitigate battery degradation, like not charging HVB if the battery temperature is above a certain level, limiting frequency of charging to full capacity and so forth. Again, Energi owners can help. Quote Link to comment Share on other sites More sharing options...
Billyk24 Posted January 15, 2020 Report Share Posted January 15, 2020 (edited) Weather related if you are in a cold(er) area of the country. Battery is not leaking. I have a 17 Energi.

Billyk24 Posted January 15, 2020 Report Share Posted January 15, 2020 Some people resort to "shore power" to heat the cabin prior to driving. Seated heats, EV later usage is better than hybrid mode. ptjones 1 Quote Link to comment Share on other sites More sharing options...

OP needs to record kWh from full charge to switch over from EV mode to Hybrid mode. ptjones 1 Quote Link to comment Share on other sites More sharing options...
