Hi,
October 2014 Peugeot ION with a 16kWh battery and 26k kilometer mileage (16k miles). I managed to get 113 kilometers (70 miles) on my very first trial (bought the car a week ago): 100 kilometers actually driven, 13 km RR. RR display seems incredibly accurate, due to my mismanagement I later went down to 11 km RR and drove 4.5km more, and the RR was displayed at 7 km.
In that state I started charging with an 8 ampere charger (OEM charger). My smart plug shows me the voltage (a bit over 220v), the ampere (between 7.2 and 7.4 A) and calculates the resulting Wattage/Power (about 1.6 kw).
I allowed it to charge over night, at a quite cool outdoor temperature (way less than room temperature).
Even after 8.5h the power consumed by the charger would remain the same as in the beginning. By then the battery gauge showed all bars and the RR indicator showed 111km (69 miles).
I left the charger on, for testing purposes (I know about the 20%/80% "rule"). About 30 min later (after 9h charging) I checked again, and the ampere had decreased to 2.8 Ampere (and 230v). The RR however was unchanged at 111km. It seemed that by then the battery was almost 100% charged, so I stopped the experiment.
What seems odd:
Usually a LiPo accumulator cell is charging at roughly the same amount of Amperes until the highest Voltage is being applied (as I understand 4.2, some variants up to 4.35). As I understand at 80% of the nominal capacity. Thereafter the Voltage can't be increased anymore, so naturally the Ampere decrease and with that the power delivered (or used). Which is why the charging time from 80% to 100% is so disproportionately high.
But my car (or rather the original Peugeot 8 Ampere charger) drew all the time, almost till the end, the same Ampere.
I have only two possible explanations:
1) the battery management system (BMS) of the ION (i-MiEV) somehow manages to draw the same power all the time. Even when it then provides maybe less power to the battery (accumulator modules). Which would be odd: it uses maybe extra energy when the cooling system is engaged, but the identical Ampere over the entire charging time?
2) the car has seemingly 16kWh nominal capacity. But I read somewhere only 14.5 kWh are "useable". That would be 90%. I read in other sources that allegedly Mitsubishi made available ALL of the capacity, without any "reserve" (for the protection of the battery, battery life longevity).
Maybe Peugeot reprogrammed the BMS so it keeps a reserve? Maybe in the 80% to 90% range the meekly 8 Ampere (at 220V) are still low enough to NOT trigger a decrease in charging power?
Anybody any idea?
