Template talk:Prius PHEV Options

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.)

Rotating 90deg for Sortable Table.

This div does not appear withing the page but is used to define the references used below. If multiple ref tags were to appear within the table only the text from the first would be displayed. Thus we pre-define them here, the only side effect being that the first "a" backlink does nothing.

<ref name=ev_range> EV range [mi] Assuming <35 mph, 210 Wh/mile (260 Wh/mi from grid) per http://www.greencarcongress.com/2005/08/solarpoweraugme.html, 1.5 miles is approximately the range with a fully charged stock battery pack</ref>

<ref name=phev_range> PHEV range [mi] During which the mileage is on the order of 100 mpg. Shows range as stated by organization.</ref>

<ref name=safety> Safety Safety in case of major accident

1. Many Lithium cells will burst in flames if penetrated. However, phosphate cathode LiIon cells (such as Valence and A123) are flame-proof.
2. SLA batteries contain lead and sulphuric acid but are spill-proof</ref>

<ref name=charge_time> Charge time [hours] From discharged to the point the pack will no longer be used in PHEV, to fully charged.

(per Orbital, SLA require 8 hr taper -- done at least once every 3 days -- after near full charge, to reach 100% and prevent sulfation)</ref>

<ref name=energy> Available energy [KWh] Because the DOD of the stock pack is limited by the Prius, only about 0.3 KWh of its energy is available (used). It is assumed that additional batteries are limited to a DOD range of:

1. SLA: 0% down to 50%,
2. Litium 0% down to 90%</ref>

<ref name=hymotion_range> Hymotion Range Hymotion states 50 km (30 miles) pure EV range. Yet 4.3 KWh calculates out to 15 miles.</ref>

<ref name=spare_tire> Spare Tire access No = original tire well is covered or occupied by the new battery pack. The spare must be secured and stowed in the rear cargo space.</ref>

<ref name=pfc_regs> PiPrius notes:

1. The PiPrius PFC40h charger doubles at the DC-DC converter between the OEM and added battery packs.
2. BMS consists of a Rudman Reg Mark 3 on every battery, which fully protected each battery on charge mode and discharge mode.
3. The BMS is programmable with a laptop, with no security locks (open source).</ref>
