PHEV Storage update

Been away from my Niro PHEV for several months. Dealer and factory had no idea what to do, but it was simple. First, I ran the traction battery down to about 50%, or 13 miles of range. Then, there is an on-off switch in the fuse panel which disconnects the traction battery. Last, the 12 volt battery in the passenger side rear was disconnected. When I got back, I just reversed the procedure and the Niro came back to life with battery SOC exactly like I left it. However, I did forget how everything worked!

What is the benefit of depleting the traction battery?

Long term storage at 50% is best for LiOn batteries

That is what Apple says as well, but I've never seen a recommendation to discharge to that level, merely to check every few months and charge it back up to 50%. I think it will self discharge fine.

quick question about the 12 volt battery in the PHEV cargo area...


what does it do ? I have an 2018 HEV and it does not have one because it is placed next to the full battery under the back seat.


Thanks.!

Normal 12 v systems battery like most cars. The HEV has 12 v lithium battery under the rear seat - it may be the only production car made with no lead acid battery.

so there is no "battery reset" in a PHEV to boost the car if needed ?

To boost the car?

You mean to recharge the 12v battery if it dies? If so, no there's no button for it, so I don't think you can manually recharge the 12v if it dies.

The PHEV will recharge the 12 v automatically - and give you a warning when you return that it has done so. The process is limited to a certain number of times so the traction battery doesn't do a deep discharge (which would make the car immobile). Not sure if there is a reset button after those recharges have ended, but I'm pretty sure you can get going. The reset button in the HEV just closes a relay that had disconnected the 12 v battery because of excessive discharge by the way - it doesn't directly recharge it, just allows you to start the car which will recharge it.

Thanks all for the info.!


It's kind of funny to have an HEV 2018 and there is no battery at that "spot" where you can keep your windshield washer fluid gallon., And on the PHEV 2019, same "spot", you have a battery... You kind of loosing that "spot" for the 12v battery.


It's like if the engineering team told them self: "Hey, we forgot something ?? .. - What dude ? - The 12v battery !! - ohh molly .... - let's take the small spot in the cargo area, and put it there! " LOL
