Battery capacity #reprogrammed !
Official MMC - Battery at 94% capacity after 2300 km
Today after many complaints that my car battery is losing amperage, now being at 42.1Ah. Real loss bigger than 10% of capacity, MMC did a capacity test on my battery. This procedure took one day and was NOT free!
The result was that the car traction battery is able to hold only 43.4 Ah.
A drop of 6% in total battery capacity was confirmed by MMC via e-mail and service bulletins. Taking into account that this battery can NOT be discharged below 30%, the usable amperage in this battery is around 30Ah. Doing the math this results in the fact that 6% from total battery capacity account for approximately 9% usable battery capacity loss in the first 2300 km. Or officially 5 km EV loss for you and me.
If we take into consideration the error between real battery capacity (43.4Ah) and BMU predicted capacity (42.1Ah) the deviation is: 3% and only increasing with time. Calculate this error form the total usable battery amperage, it represents almost 3 km EV range lost only to BMU software error, in addition to the "natural" 5 km degradation loss.
According to Mitsubishi, after 2300km or 4 mouth this is "normal" (to have a 8 km EV loss) !
Mitsubishi is getting incentives or free money from the government for every Outlander PHEV sold here based on the official declared EV ranged. This value is 57 km!
50 km is the EV range for the car to qualify for up to 4400 euro!
This car will NO longer offer an official range equal to 50 km based on the BMU values after the first 600 km since delivered or 2300 km taking into account the officially measured battery capacity degradation done by MMC!
In reality, my ordinary 34 km EV max (No AC) range is more like 28 km after only 4 month or around 22 km if I use the AC.
Imagine how bad things will be when the battery will have officially 70% capacity!
