My granny charger from a 10A socket pulls only 7A (1600 watts) maximum. I don't mind that because I get a full 63km charge overnight, at a low charge rate, which lowers the chance of a battery meltdown.
It's a HS PHEV by the way.
Hard to know, but something flattened my battery and I truly think my battery is ok, after all it's a deep cycle battery. The problem is not resolved and it will happen again, hence I'm carrying a portable jump starter that I already owned. Next time I won't go to the battery in the back of the...
Yeah,
I reckon owning an EV (or any modern vehicle), is like owning an iPhone 20 years ago. Nothing worked properly without jailbreaking. Rapid use of very modern technology can bring you a very glitchy vehicle. I just hope there isn't a fatal flaw.
Oddly enough, after a jump start the battery seems to be holding a charge and the problem has gone away. It's like something was left on to cause the battery to go flat. It seems to me in a modern EV car it's impossible to leave something on, it's all taken care of for you. I'm beginning to...
I got a beep at about 2am in the morning. I got up and took a short drive. That got me to the morning. I now carry a 12V LiFePo4 jump start pack, till I resolve this battery issue.
I have a 12v charger at home, I'll be there tomorrow after a 144km run. I just hope I don't have to call MG assist to get going in 8 hours time. It seems there is a threshold voltage below which the system will not "boot". Once it boots I think the Traction battery charges the 12V battery.
I also note, that the warning toots that warned of a low 12V battery continued until there was insufficient voltage to make the horn work. A self fulfilling prophecy. I think the software engineers could do with a little schooling.
I do a 144km drive at least once a week, maybe twice. Rest are < 60km. The battery would be 2yrs old, I suspecting it's faltering, probably a monitoring system draining it 24/7. I also gather that when charging the 380V 16ah battery the 12V battery doesn't get a charge. Go figure.
Today my PHEV started tooting the horn but at a very sickly volume. Nothing at all worked. It kept intermittently tooting at a more and more feeble effort. I climbed into back and manually (with a screw driver) opened the hatch, measured my battery voltage at about 7 volts. Called MG assist, a...
