I would value your advice. I have just bought a 2011 Peugeot iOn battery car, and its automatic charger does not switch off until each cell reaches 4.06 V. Do you think this is too high? Would it be better if I switch off routinely before this automatic cut-off. Fortunately, I do not need the full range.
Details are as follows. The Mitsubishi iMiEV specifications include
16 kW 58MJ lithium ion battery pack consists of 88 cells …. in series at a nominal voltage of 330 V …. developed by Mitsubishi and GS Yuasa …. and manufactured by Lithium Energy Japan.
Normal charging from 230 V ac ( I measure 9.4 amp.)
“is via a five-pin IEC62196-2 Type 2 point. Three large pins are the line, neutral and earth/ground. The two small pins are a control circuit. This circuit enables the charger to be cut off when charging is complete ….. the lead has a local plug at one end and a Mennekes connector at the other …. there is a ‘floating’ control box in the middle of the lead that limits the current to 10 amps so enabling an 8-hour charging time from complete depletion.”
The Peugeot ion handbook differs only slightly:-
Lithium-ion type 1 N ZKZ Z
50 Ah 14.5 kWh 300 V
Normal charge:- 10 A x 8 hr. 8 A x 11 hr (20 to 25 degC)
I have twice asked the local Peugeot agent, who sold the iOn, to answer this question, but I’ve had no reply after a fortnight (perhaps they are trying to translate an answer in Japanese?)
The Mitsubishi specification figures of 330 V is 88 x 3.75 Vpc.
The Peugeot figure of 300 V is 88 x the familiar 3.4 Vpc
Any ideas from anyone here? My response was "I would be inclined to let a factory builf car sort itself out".
