Don, wouldn't starting the car also charge up the 12v battery when storing long term?
12v battery concerns me more than the traction battery - seems strange that it's a battery you have to top up instead of a sealed unit like most ICE car batteries. Don't want to pay dealer to replace it - would rather do it myself but my car came without a user manual so I don't know the code for the radio. I'll maybe connect up the 12v battery to charge every so often but should this be a problem if driving the car almost every day?
The following Transport Evolved video claims that the reason the 12v batteries die is that electric car 12v batteries do not have high loads going through them as would be the case with an ICE car and the high starting current in an ICE car "breaks down deposits that have built up on the plates of the battery over time"
Would using the 12v battery with a higher powered inverter help to do this or would it not draw enough power?
(I am aaware that it probably needs to be replaced at some time soon (as it would with an ICE car) but I want to maintain both my batteries well!
I would be interested to see my traction battery's actual capacity so may have to buy the obd adaptor and hook up canion (or EvBatMon)
The car only has 25,000 miles on it but is coming up for 7 years old.
I think it was used fairly frequently but it may have been fully charged every day with the "granny charger" - 240v - 10A ~2.2kw and charged when the battery already had a high SOC.
Apparently it has never been charged using CHAdeMO although not sure if this would make much difference with non-frequent CHAdeMO charging. It rarely gets above 20C (~70f) here anyway so do'nt know if I should start using the quick charger and go on some more challenging journeys - I don't like pushing the battery to its limits. In 500 miles of ownership, I've never let the battery go below 5 bars.
Luddite, welcome to the forum! Whereabouts in Scotland are you (I was born in Edinburgh)?
JoeS, Thanks. I'm currently residing in Dundee. We currently have free parking for all pure EV's in Dundee and free charging/quick charging but not free parking for hybrids - there were too many mitsu outlander PHEV's bay blocking.
Mainly charge up from home anyway but it's good to know the network is expanding - free charging in most of Scotland
