high voltage battery recovery

[gigdriver]

I'm preemptively studying how to care for a 2017 Fusion Hybrid myself. This particular model is NOT one of those with apparatus for connecting it to household current, so if need arises I'll have to try recharging its high-voltage battery without that convenience.

Unfortunately, I am not readily finding instructions on doing so. I assume that the HV battery has accessible positive and negative terminals and safely can be serviced by an attentive do-it-yourselfer under proper guidance.

 

Can anyone on this forum offer tips on recharging the HV battery on this model or point me to a guide for doing so? Thanks!

It really isn't a user serviceable thing. I don't see any specific instructions for a HEV (just PHEV) for if the car will sit for 30+ days. The PHEV says to plug in, and either disconnect or trickle charge the LVB but the LVB should get trickle charged from the HVB charger.

 

Generally dealers don't even keep equipment around to "charge" or "balance" the HVB, even less so with LIon batteries versus NiNM the older ones had. They usually have to request it to be able to use it. Some of the older Escape Hybrids had a way to jump the HBV with the LBV but they removed it saying it wasn't needed (even though there were times it was actually needed and used, like extended periods of sitting).

@bangster. Given your answer, my intent would be to call all local dealers to see which have appropriate equipment for servicing the HVB. Beyond that I might also check with fleet maintenance garages at the airport or other rental operations for referrals. 

 

Please comment if you can on what will be involved in replacing the HVB if it comes to that. Some specialized sort of fork lift would seem necessary. Any. idea the cost?

Folks have 10 year old Fusion hybrids with over 150k miles on the original battery.  I don’t think you’ll have any problems.

@akirby Thanks for the response. It made me realize that my original post without stating it reflected my concern over the kind of battery in Ford Fusion Hybrids being now Lithium-based and differently vulnerable to discharge--perhaps perilously more vulnerable--than the sort of battery formerly used in this model. Can you comment on that? As originally stated, the model year of Fusion Hybrid in question is 2017.

li-io batteries are less sensible to deep discharge and do not discharge over time if not in use. That said, if charge in cell ( individual cell of batteries) go under a certain level it will not charge back. 

On that note if you use your car regularly you should not have any problem with the batterie. The hybrid system is program in a way not to deplete the hvb. From experience the hvb should last the lifetime of the car with some rare exception .

The car manages the HVB automatically. There's nothing you need do except follow owners manual recommendations for long term storage when the need arises.
