hey guys,

long time no see. I have been quite fascinated about this car, and all the EV technology. And this is what I have came up with

"Fe" battery is short for LiFePO4 (Lithium Iron Phosphate) battery, this is a new type of battery that is similar to the Lithium Ion battery (Chevy Volt, as well as your cell phone) but so much newer and better in the following ways.

Power Weight ratio: Slightly below Lithium Ion but not much
Price: Slightly pricier than Lithium Ion
Charge cycle: 2000 vs 1200 for Lithium Ion (A HUGE HUGE HUGE plus)
Greenness: Landfill approved vs. Special waste treatment for the Lithium Ion
Capacity vs. Lifespan: Fantastic at around 2000 cycles, the battery should still hold more than 80% of its original capacity.

And it turns out the LiFePO4 battery is so green you could literally eat it, and it has been done by the founder of BYD at a certain press conference. And BYD being the leader in this new Fe battery technology, it is in a very very good position. The BYD F3DM is already on sale, with this Fe battery. And by the time the Chevy Volt is on sale with its outdated battery, BYD would have already sold 500,000 F3DM and god knows how much e6's.

I forgot to talk about the quick charge.

for those not too familiar with electronics, when you charge up a car its very similar to...well filling up a car. In a gas station get a super large hose that would deliver a considerable high flow rate, thus filling up your car with petrol in around 5min. But if you have a household pump, say about the flow rate of a fish tank pump it would take you hours and hours to fill up your car.

your regular household socket, delivers a max of 120V and about 15A (20A at some places, but rare). For running a car, this "flow rate" is similar to the fish tank pump it would take hours and hours to charge up the car. but if there were charging stations with say 220V and 100A you could charge up the car in a lot less time.

well you may think that, why not have 4400000V and 10000000A so I could charge up my car in 5min? well the answer is because the batteries would blow up. there is a maximum amount of "flow" the batteries could take. what BYD has done is created a battery that is capable of charging up 50% in 10min assuming you could deliver enough "flow".

Hi Johnny Blaze,

Well personally I am a mechanical engineering undergrad, and to be a mechanical engineering they require you to have a small level of electronic knowledge. Below are some of the links from wiki, where I learned most of this stuff.

LiFePO4 (Most of the important data is on the right box)
http://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

Lithium Ion
http://en.wikipedia.org/wiki/Lithium_ion_battery

BYD F3DM info (again important data on right box)
http://en.wikipedia.org/wiki/BYD_F3DM

BYD e6 info
http://en.wikipedia.org/wiki/BYD_e6

Chevy Volt info
http://en.wikipedia.org/wiki/Chevy_Volt

BYD CEO eat battery

let me know if there are something you don't understand

Wiki is not that resource, to consider it's info as an axiom
it's a pitty but sometimes the content is blowing my mind...
Hi Johnny Blaze,

Wiki was not my only resource, if your actually interested you could look up the following electric motorcycles

zero motorcycles---> they run the LiFePO4 battery as well
brammo enertia ----> LiFePO4

It sounds like no matter what I say, you won't believe it. Just google up LiFePO4, and you would get plenty of information. A lot of EV builders like to use it as well.

And regarding the comments about e6 vs. Volt, there are two things you must keep in mind

1. Volt is a plug in hybrid, and e6 is pure electric

-Even when the volt is within the 40mile electric range, its still lugging around a very heavy engine and components that are required to run that engine.

2. Volt is planning to run the outdated LiIon battery, while the e6 is running the space age LiFePO2

-Not only is GM using an outdated battery, it is sourcing it from LG in Korea. GM just doesn't have the battery technology/facility to produce the Volt all in house.
-And keep in mind BYD is a battery company, and source to many electronic manufactures.

And for 40K, its steep for the normal people but tree huggers would pay that for a electric car that could be purchased off the shelf. It would get cheaper, just a matter of time. (Anyone still remember how much the first generation Ipod cost when it was launched in 2001??)

Keep in mind, at the moment China has the leading technology in terms of batteries. And BYD is China's leading battery manufacture.
