This from Rich Rudman Manzanita Micro: " I have two systems installed. We have 10 miles range EV only I am not sure what the test variables are for Phev running.

The same charger that does the dc/Dc does the Grid recharge. We can sustain 30 plus amps of grid power at 240VAC That's 7.2Kw. We have data logs on a recahrge at less than 25 minutes. So we are in the .3 hours recharge range.

The BMS is a Rudman Reg Mark 3 on every battery. It is fully protected on charge mode and discharge mode. Got the test done yesterday. Sweet operation. Oh yea the BMS is programmable with a laptop. With no security locks. I am doing this open source. We can and have extracted 4 Kwhr from the add on pack.

The delivery cost is targeted at $10,000. I have my doubts that I can make the profit I want at this price. The brutal fact is anybody bragging about selling one of these kits for less than 10K is not looking at the bare bones costs of the hardware. I have to. since I am using my own funds, not some investors.

Spill proof Lead-Acid?

Why are the Lead Acid battery spill proof? Yes, I know, they are sealed. But, in case of perforation, in an accident, won't the acid come out? DavideAndrea 21:00, 10 January 2007 (CST)

Re: Spill proof Lead-Acid?

No, it won't spill like a flooded cell would. The electrolyte is suspended in fiberglass mat separators (a.k.a. absorbent glass mat - AGM.) In theory, even if the battery is punctured, within the rated temperatures, it will not spill since the electrolyte is in the mat, although a solid acid powder will probably come out in small quantities, but not in a liquid. If the battery is heated beyond its rated temperature (overcharge, short, etc), the electrolyte becomes liquid and can (and usually does) leak. A big concern with a punctured battery are the lead plates and the lead powder that gets formed and comes out when punctured, which is a health concern (acid is too, but easier to deal with and clean up.)
