Re: Electric Car (EV) Home Charger - 32A - Options?

I recently bought an Ioniq and I'm very happy with it. I also bought the Delta home charger / EVSE to go along with it (purchased from Hyundai and it comes from JetCharge). After getting the EVSE installed on its own 32A circuit, I am only getting 4.5kW charge rate so I went back to the supplier an...

@weber PIP-5048MGX = Axpert MKS III See solarpower24.it And don't forget PIP-8048MAX The MAX series are very much like the MGX. They both have the new feature to program timer settings for Output Source Priority and Charger Source Priority Thanks for those. I already had the PIP-8048MAX in the spre...

Re: MKS-II-5KWB Repair Please help

... I think even if you install new inverters the cause of this failure may still be there, I feel it could be a voltage spike on the incoming grid/generator to the inverters and with that blue capacitor (but is it a capacitor maybe its a MOV so can we have a picture of them with the writing on the...

Re: MKS-II-5KWB Repair Please help

So I managed to contact with MPP solar & Voltronic and it looks like the new versions of the inverters are quite different from this old style. They didn't send you a brochure for the inverter model that yours are clones of! It is the PIP-5048MG, as I mentioned earlier. See https://www.ebay.com/itm...

Like paulvk, I worry that 9 of your panels in series may be sailing a little close to the wind, with regard to the maximum open circuit voltage of 450 V. How many cells are there in your 360 W panels? I see most with 72 cells, but some with 96 cells. Assuming 72 cells, I see Voc's of around 48 V at ...

Re: Aftermarket iMiEV battery upgrade project

That's great news. Am I correct in saying that you've shown you can access 80% of the capacity of the new battery? What was the lowest cell voltage it got down to? Do you have any hypotheses as to why you don't need (a) current unspoofing or (b) cell voltage spoofing? Surely that horrendous circuit ...

Re: How to tell a kilowatt hour from a kelvin week henry

This may also be of interest: Battery capacity is called C . This is in italics because it is a quantity symbol, not a unit symbol. Its units are amp-hours (Ah). In the case of lithium-ion batteries, we are concerned with the maximum rate (i.e. maximum current) at which they are allowed to be charge...

Here's something I wrote for a battery course for Electricians, about the relationship between amps and amp hours. It could easily be reworded to refer to watts and watt hours.

Re: PIP inverter repairs and hardware modifications

Not necessarily across the 15 V or 12 V supply, but at least involved in producing those supplies. Possibly the electrolytic across the supply pins of the PWM chip involved in making those supplies.

Re: Low cost BMS

That sounds good 4Springs. Although I've never felt the need to use explicit PWM, because when you just turn bypass on or off at the threshold (e.g. your lowest + 10 mV, no hysteresis), they will balance as quickly as possible, and when they get close to balanced they naturally enter into a sort of ...

And most importantly, the protection device closest to the battery must have a kA rating (interrupting capacity) that is greater than the maximum short circuit current of the battery. Otherwise, in the event of a short circuit, it will not go open circuit but will continue to arc over and will not p...
