We know that for the sake of extending the traction battery life, it is better not to charge it to 100%.

Mitsubishi is probably limiting the maximum charge level somehow, so the battery would not degrade so quickly.
But many of us don't need the 100% range everyday and would like to have some convenient way to limit the maximum charge to, say 80%.
So far I have found on this forum only solutions with manual timers - which is cumbersome and impractical to use.
Unfortunately, Mitsubishi iMiev does not have an option to charge it to 80% only as Nissan Leaf has.
Has anybody tried to create some automated switch based on current state of charge (SOC) and/or current battery voltage that would disconnect the power to the charger when some preset charge level is reached ? Some device that you would have in (or outside) your car that will do the job without the user ever bothering about it ? If the device could be also used by non-tech users, without any cabling and drilling that would be great.
My personal idea would be a (remotely?) controlled switch (to cut off the power), and the information about SOC taken from the CAN bus ?
How about easier solution, like taping to main battery cables to measure voltage (sending signal to cut-off switch at some voltage level) ?
I know from me it's just ideas without really putting something together, but maybe somebody has got further and can share some experience.
Thanks to everybody for sharing ideas/solutions
