Outlander PHEV Sub-Zero Operation Question

[PHEV07]

I was going to upload a video of the procedure but it was too large.

I will try again later tonight or tomorrow

I was not able upload video. Hope this helps

I could live with that except that without an Embedded Battery Heater in the Battery Pack, when not charging by Charge Port Cable the Battery Temperature drops down to and stays at the outside Ambient Temperature since the HVAC does not warm up the Battery when it is on.

Driving my 2024 in the city and Highway last Friday when Temperatures were -16'C with the ICE running 100% of the time, driving the car on ICe did not increase the Main Battery Temperature at all.

My biggest complaint is that the 2023 to 2025 PHEVs no longer has an embedded Battery Heater inside the Battery Pack

Looks like Mitsubishi Engineers worry more about the ICE than they do about the Main Drive Battery since they programed the car to demand that we add at least 20 L of fuel every 3 months but decided not to include an embedded Resistive Battery within the Battery Pack.

I can now confirm that plugging in the car does heat up the Battery as my Temperature gauge increased from being on the left vertical bar (1/5th way of horizontal bar outside temp was -12'C) and increased to 1/4 of the gauge, after charging.

This heating however was produced by charging the cells at 3.7kW. This heating is not done by any Heater as there no longer one in the Battery Pack.


It is important to add that at -12'C, when the Battery Level was at 5 kms left in range the car did go into EV Mode but was in Limp Mode because pushing the pedal to floor did not power the wheels past 30 kph.

Sorry, wrong Photo. The one I took at midnight did not save.

This is similar to my experience (except for any warming effect when plugged in). The point to remember is that when the temperature drops sufficiently, the battery is locked out and will not charge. The same is true once the battery is fully charged.

The absence of a battery heater, as you say, is the root of the problem - the same battery heater that was advertised as standard equipment in the '23 model but was not included.

The issue of cold start operation specifically aside, the way it has mistreated (and lied to) its customers should serve as a loud warning to anyone thinking about even buying a lug nut from Mitsubishi.
