Engineers of Nissanís Leaf, which made its debut in 2010, wanted their car to have a battery that wouldnít clog up valuable rear-seat space. Instead of placing the lithium-ion batteries in the back seat and trunk, they created a 24-kWh pack that resides under the floor. (Source: Nissan)
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.
A half century ago, cars were still built by people, not robots. Even on some of the countryís longest assembly lines, human workers installed windows, doors, hoods, engines, windshields, and batteries, with no robotic aid.
