Electric Car Batteries: Lithium!

probably heard that all the new car batteries coming out in the cars the major automakers are lithium ion right? So you might ask, the difference between lithium ion say, lithium iron (LiFePO4)?

Lithium iron (LiFePO4), the EV conversion crowd’s battery, is actually a lithium ion too.

It just comes in basic shapes:

prismatic CALB, Fluxpower/Voltronix, Realforce, cylindrical (A123, Headway); and (Nissan and other OEMs).

iron phosphate (LiFePO4) is a tamer form of lithium ion than you find in your but it will still take you 100 on a single charge. Lithium is another type, and I say more lithium polymer here .

So I got a to talk with Mike at Lithium Storage about electric car batteries. He sells LiFePO4 battery packs for EV and I’ve found him to be quite about lithium electric car in general. I also spoke Jack Rickard from . who has done several AC electric car using different brands of cells, and he’s put the LiFePO4 in both AC and DC systems.

Lithium Ion Pouch Cells

Mike from Lithium Storage

The OEMs (Nissan, Chevy, like the pouch cells for electric cars.

These the benefit of being thin and to build into large packs. And some have a bit energy density. But these cells are more expensive and greater attention to temperature.

This is why the new Tesla Model S has a (an EV with a radiator. ), to keep the in the required temperature range (I can scenarios where the radiator a hole or a leak and the battery gets fried).

For another Kokam cells (lithium come with very heating and cooling systems.

batteries also expand they are charged and discharged, so have to be contained.

LiFePO4 Car Batteries

For electric car conversions just nothing better the LiFePO4 electric car batteries now, and the most readily ones are the Chinese prismatic 100 miles on a charge is NORMAL these. The price is reasonable. safe and reliable.

And they’re to ship anywhere here in the US.

with Mike at Lithium

Lynne: I see that the Chinese cells are identifiable by their like sweetener packets at the bar! Yellow? Blue? anyone?) Does each stick with just one

Mike: The color thing is Here we go:

Fluxpower/Voltronix cells in Green and Yellow. CALB Skyenergy) cells come in Blue or Gray. Thundersky USED TO come in Yellow Thundersky is now bust).

Winston cells come in Yellow. cells come in either Green or Black. Realforce come in either Black or GBS cells can be found in either or a Blue-ish hue.

Hipower cells come in

And yeah, I’m sure I get you pink batteries if you wanted.

would you say are the major distinctions each type? Seriously, all seem about the same to me. I make heads or tails out of the of the graph curves.

Is there a Well, Skyenergy, GBS and Sinopoly among the many manufacturing under old Thundersky. So the appearance, and chemistry were nearly These three have all out on their own and now things are slightly

I’m not familiar enough GBS to make any claims regarding chemistry, but the case design has to incorporate a neat cap and awkward system.

Skyenergy is now CALB. cells can be found in identical to Thundersky, but colored blue. the CALB cell has a slightly voltage range, a higher C and lower failure rate.

cells match the old Thundersky, but new are a bit smaller in physical size.

I note that Thundersky offers cells, but the data indicate a higher top voltage I’m comfortable with and the cycle life is falsely

Thanks, Mike.

Jack: We use (yellow) or CALB (blue) somewhat indiscriminately. Both are LiFePo4 cells. We’ve had luck with them.

In the of the Mini Cooper Clubman, we use 100Ah cells and 112 of them to get 375 volts. In the lower voltage we use LARGER cells of 180 Ah.

Lynne: So they both fine, they cost the same, it’s mostly a of what fits in your space and battery boxes,

Jack: You got it.

What’s Good About Electric Car Batteries?

Lithium longer.

A lithium pack last you something like years. This brings the down to the point where it the same as, or even less a comparable lead acid pack. Lithium is lighter.

A 144 system with 200 AH (that’s peppy and will take you a way between charges) will around 720 lbs worth of lithium Compared with 1500 lbs or so of

Lithium mining is environmentally and human friendly.

I listened to NPR special on electric cars the day, which is kind of but has a really interesting discussion of the of lithium mining. It is not mined at but rather comes naturally in a form that is found out in the in South America (The in Bolivia), sun-dried by locals, and to its destination. No miners trapped no fracking, no toxic waste.

likes speed.

Freeway won’t intimidate your electric car batteries; no matter kind of motor you’ve got in electric car, lithium keep bringing the amps. pretty tolerant of rapid and discharging. The lead foot tax is of an issue.

LiFePO4 is safer lithium.

If seen the flaming laptop videos, you’ll appreciate set of YouTube videos where pounding a nail into a battery and nothing happens. LiFePO4 is tolerant of deeper

This might be one of the best of lithium.

Mike says: benefit to switching from to lithium — aside weight loss — is the DOD of discharge) that lithium will tolerate. Lead shouldn’t be taken below 50% So lithium not only has a higher density, but it has a deeper use of stored

Basically AH to AH, lithium will provide more useable than lead.

What’s Not So About Lithium Electric Car

Reputable LiFePO4 Battery

Mike told me a little how to tell a reputable LiFePO4 EV distributor from. the other

Briefly, a reputable distributor:

credit cards; Has a good in public forums; Responds to inquiries in 24/48 hours; openly about what do and do not have in stock and how long it take to get what you order.

expensive initially.

but it balances out in the run, because LiFePO4 car batteries last longer.

Some of the Chinese prismatic have gotten sort of a for being unreliable — but are no longer in production. And some US have gotten a reputation for fly-by-night.

Lithium Storage has been a while, has a good reputation, the come with a two year and I trust them. It takes a

You have to order your pay your money, and wait. If a is coming from China, it can 6-8 weeks to deliver. If shipped USA inventory, it should only five business days at to ready a shipment for delivery.

on the battery warranty from Storage: A lithium pack is to last 2000 cycles at 80% DOD of Discharge) = 6 years if fully and charge every day. And cycles at 70% DOD. Most will not be fully reach 80% day, many not even

In those cases the life reach the 10+ year mark.

Management and LiFePO4

Mike and I a little about battery systems and the need — or of it — for management. Turns out I was all about WHY lithium batteries to be managed.

Lynne: I heard lithium ion batteries need management systems because is prone to thermal runaway.

Mike: Thermal runaway is not of an issue for the Chinese Prismatic or cells.

The reasons for management are warranty and to keep the cells within the optimum voltage range. The BMS Management System) serves to monitor cells and send (this could be via screen or or dash light or relay cutoff, etc.). Think of it as insurance for the expensive battery

Otherwise cell/s could and suffer reduced life discharge and prematurely fail.

folks are just fine a BMS. But you have to religiously the pack.

But lithium is sensitive to and cold, right?

Actually, batteries are far more sensitive to than lithium, though cells don’t like to below 32 deg F. — the lithium plates the other side and the life of the cell.
