but even my bike is now obsolete so no new batts from bosch and there doing it to everything so force you to buy another car for 60k in 5-10 years as well we cant fix it because the software is to old and the new part cant pair with the os anymore.
There are Windos 2000 drivers for that card, but you have to install 98 first, install the Windows 98 drivers, upgrade to 2000, then install the new drivers. But the software isn't as good - I still have one working on a PII 266...
The electric mini is a retrofit using large prismatic cells, and a weird shape to fit where they've ripped out the transmission and fuel tank, other manufacturers use cylindrical cells in varying configurations etc. etc.- nothing is compatible... but it would be better for everyone's pockets if they were, for when new battery technology arrives.
It doesn't even need to be that dramatic - hackers could simply turn off the air conditioning on a hot day when parked and lock the doors. Dead in several hours...wont matter they will brick the bms so wont have any choice of repair bar buy a new one even if that means a hole new car as thats what they want unfixable expensive crap to track you 247.
and a subscription fee for all the extras that you paid for anyway of course.
and then one day this will happen.
Because charging to higher voltages such as 4.2V/cell or more accelerates Solid Electrolyte Interface (SEI) degradation and this significantly reduces cycle life...unfortunately, most BMS do not start balancing until 4.15V/cell or higher. Fortunately, most well designed packs with decent cells tend not to go out of balance very quickly.
It depends on the charger/battery. One brand is <1w so shows 0, the other two are <2w.
I read there was a Chinese EV (car) maker at the Paris motor show this year using "blade" batteries... i.e. you slide old ones out and new ones in, rather like changing AA batteries in a torch.
Are there any BMSs which will do balance charges at lower given voltages? Seems to make sense to always do a balance charge, to keep battery life of individual cells as similar as possible, yes not at full voltage.
Over a couple of thousand mixed partial and full balance charges, could the chemistry of individual cells in a pack become widely varied?
How much would Peter charge for frictionless synthetic sapphire bearings?
I've not had problems after about 200 cycles or more of 41V charging with several of my 36V packs. The recommendation by Grin is to do a balance charge once every month or two. So only charge to 42V when you need max range or for occasional balancing.
If they are always balance charged (to a lower voltage than maximum), the internal resistance would remain similar? If the cells were manufactured consistently.
