These companies play the prices very close to the vest, Cabe. But if we do a little arithmetic, we can get in the ballpark. A 500-kWh battery at $1,000/kWh would be a half million dollars. If the battery costs are coming in lower, say $500/kWh, it would be $250,000.
Looking at these batteries and their elaborate housings it hits me; how amazing that we can pull enough resources out of the earth to make it all. The resources seem endless, though I know they are not.
That Grid lithium battery must cost a fortune. Do you know the price?
AnandY, actually the range depends on the weight of the car and the power of the motor.
One of the other issues with batteries is the amount of time to charge them. A large pack like the one you mention, may take hours to charge (unless you have a special charging station). This is just another "problem" to be solved.
Envia Systems is doing a great job in liitium-ion battery development. The electric car industry faces two major challenges: the high cost of batteries and their limited range between charges. Envia Systems, a startup developed a rechargeable lithium-ion battery with an energy density of 400 watt-hours per kilogram, the highest "energy density" known. They claim that once the electric car is fully charged then car can run upto 300 miles.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
