Won't run in EV mode after fast charging

[BobK]

I wonder if anyone else has experience with this. I have a 2023 and frequently take long highway trips with it. If I can spare the time, I will stop to charge it up at a CHAdeMO fast charger to about 80%. What I find is that the car behaves differently than when I leave home with it fully charged. For the first 5-10 minutes it will not go into EV mode at all, then after that for about 40 minutes, it will frquently drop out of EV mode when going uphill or accelerating. When I use normal mode, it will stay in serial mode (without dropping the charge level of the battery) for about 50 minutes before starting to use EV. I don't recall this happening after I first purchased the car but I noticed it this past winter and it has behaved this way ever since. I have tried it with no airconditioning or heating and it doesn't seem to make a difference. I have close to 60K on the car and I wonder if this indicates anything about the shape of the battery. It seems like even though it is charging to 80% the battery is having trouble providing the full amount of current to the motors. The fact that this seems to change over time makes me think it is heat related. Any thoughts?

Like you, my first thought is that fast charging is over-heating the battery, and therefore you have reduced power until it cools down.

Took me a while, but I found this in the manual for mine:

NOTE
Repeatedly performing only quick charging may reduce the battery capacity.
In usual charge, normal charging is recommended.

To maintain the capacity of the drive battery, the following is recommended:

• If you repeatedly perform only quick charging, fully charge the vehicle in normal charging mode every two weeks.
• Do not repeat charging near the full charge level.

The quick charging gives priority when the normal charging and the quick charging are
performed at the same time. At this time, the normal charging will be stopped.

Even if the operation mode of the power switch is OFF, you may hear the operating
sound of the cooling fan for cooling the drive battery during charging.
This is not a malfunction.

I also have 2023 model and there is no way, or reason, why I would plug-in to a CHAdeMO fast charger !

Long trips burns fuel and exercises the engine..

I generally have tried to book my lunch break at a fast charger on long trips - but it isn't very often that a fast (or any) charger is available for many of the places I travel. I probably fool myself that I am contributing a few less molecules of CO2 when I travel this way. It certainly does not make any economic sense because our local chargers bill for time at the charger (at a high rate), not the amount of power used and the Outlander draws slower than most BEVs.
My engine is not lacking for excersize.

True. Let alone to find a CHAdeMO Charger anywhere.

Sure hope that Mitsubishir decides to do the right thing and replaces the CHAdeMo with a NACS, after they install a Battery Heater to all 2023 and newer Models

A small Restive Heater for the Cab would also be nice, for when it gets too cold to run the Heat Pump.

Lately it is 1 Step forward and 2 steps back, with Mitsubishi.

I do drive a 2024 GT Model in Central Canada where Temperatures reach down to -40'C.

Well it looks like you did not get the right car for the zone you’re living in.

I had previously owned a 2018 and then a 2022 and both of these performed very well for my region and performed very well during cold spells of Temps reaching -30'C and lower. I was able to leave the cars outside at these temperatures and not plugged in and the car would automatically turn on the Battery Heater on when a temperature of -20'C was reached and tge car never failed to start. Also I was able to remotely Start tgd ICE in these Cars. Also when plugged in the Cab Heater worked because ggeh had a Resistive Heater for the interior heat.

The 2023 to 2025 Models have been shown not to have been designed to work in Cold weather even though Mitsubishi Motors is selling these cars to cold regions with the claim that they were well suited, but now in late 2024 they advising owners that these cars may fail start in cold weather.

Thus the Class Action Lawsuit against against Mitdubishi Moyors in Canada and the USA.

The 2023 to 2025 models have Battery Heater embedded in the Batteey Pack they have no Resistive Heater for interior, do have a Heat Pump that no longer operates at Temps-25'C or lower and we have no way to remotely start the ICE but worst of all Mitsubishi Motors now advises that the car may not Start nor be able to be charged at temoeratures lower than-30'C

As stated before the 2022 and prior models never had these issues.

I've just bought a 2025 few months ago and did not have any issue yet about cold weather or any. Hope we never get -30'C here at Trois-Rivières, Québec. Well, the cars don't have Battery Heather anymore but they have bigger battery and better millage displayed. That did permit 1000's of us to have 1000'$ rebates from Govs. How long is the Class Action Lawsuit running?

Class Action Lawsuit started in January 2024.

Yes the 2023 to 2025 do have a bigger Battery, which went from 13.8kWh to 20kWh but....

And here is the big but.

Since Lithium-Ion Batteries are designed to work best at 22'C, the operating temperature range is between -20'C to 60'C. Since there is no Battery Heater in the Battery Pack, once the Battery Temperature starts to drop to temperatures lower than -20'C, the Battery Efficiency starts to drop exponentially and when it reaches to temperatures lower than -30'C, to protect Battery, the Computer may turn off the Battery to prevent it from being used or even Charged

In the summer I was able to drive 95 to 100kms on a full charge thru the city with no HVAC on

When the temperature dopped to between 10'C to 5'C with no HVAC I would only get 40 to 45 kms on a full charge

When you are no longer able to drive in EV Mode, the ICE does kick in but it is the Battery that drives the Electric Motors. So as the Temperature drops so does the efficiency of the Battery which causes a drop in the efficiency of the Car

Keep in mind and you can see this for yourself by viewing the meter on the dash. When the ICE RPM increases so does the kwh Meter.

Yes as the ICE runs it does charge the Battery but at a reduced Efficiency which causes a greater cost for fuel.

This drop in Efficiency is due solely by Mitsubishi Motor's decision to remove the Battery Heater from the Battery Pack

No other Car Company manufactures an EV or PHEV without a Battery Heater.

I understand your concern out there in a nordic situation. Hope you’ll be hearded. On my side I ask to be able to activate as needed that Battery Heather.
