What is the best electric car battery?

Question

I am looking for electric car batteries. What is the best and where do i buy them?I live in Canada Saskatchewan.

Answer 1

The One That has the deepest cycle and puts out highest power for the longest period. which would make it the Lithium Ion.

Answer 2

Hydrogen run cars would be more environmentally friendly.

Answer 3

super capacitator or a lithium ion battery

Answer 4

in your province, contact Battery Direct located in Saskatoon they should be able to help you with what you want.

Answer 5

I can't tell you unequivocally which is best but here are a few of the leading battery companies.

A123 Systems  

"General Electric has officially confirmed its $4 million investment in Norwegian electric carmaker Think Global, a development Green Wombat reported back in December.  GE Energy Financial Services (GE) also has invested $20 million in Massachusetts lithium-ion battery maker A123Systems, which will supply batteries to Think. General Electric said its scientists will work with both Think and A123 to improve battery technology for electric cars to “enable global electrification of transportation.”

AltairNano makes a lithium titanate battery used by Phoenix Motorcars.  They have a 130 mile range so far, but expect to improve on that.

They are building light utility pickups for the Mexican market.  Of particular interest is the ability to recharge the battery in 10 minutes, using a 440 volt charger.  The onboard plug in charger takes 6 hours.  

Tesla cars have the best range so far, at over 200 miles, and impressive performance. Their luxury roadster goes 130 mph and does 0-60 mph in under 4 seconds.  I think they developed their own battery.

Ovonics,  a joint venture between GM and Energy Conversion Devices invented the nickle metal hydride battery and is developing lithium ion batteries.

Advanced Battery Technology is another one.

Valence Technology is another

This site has lots of information on batteries. I've only scratched the surface here.

Ultra-capacitors are new twist for storing energy in cars and other applications.

Maxwell Technology is a notable developer of this technology.

Answer 6

Use hybrid batteries. The NIMH batteries used in hybrids are wonderful for EVs, but the patents for those advanced batteries were bought by Chevron/Texaco, and now the licensing of those patents prohibits their use in pure electric cars. Absolutely true story. Read about it here:

Most conversions still use old 100-year-old lead-acid battery technology, which is relatively inexpensive (the battery pack in my EV costs under $1000) but your driving range will only be about 50 miles. Various vested interests have been able to put up roadblocks (like the NIMH story above) to more advanced batteries.

However, if you're a bit of an engineer, you may be able to get some new Chinese Li-Ion batteries. A few hobbyists I know of have been able to obtain and use these, but you'll have to design your own charging system (or get help from an engineer.) Link:

Look at the chart on this page - the batteries beat every other technology there, and cost the least per watt.

Good luck!

Answer 7

Depends on your budget and your point of view. Lithium Ion batteries have the highest energy density that I know of. But they're expensive, and we don't know how to  recycle them yet. Lead Acid batteries are heavy, but they're cheap and easy to recycle.
