The electric car places heavy demands on its batteries

Whether making the vehicle an electric car or develop a new model, the batteries of electric cars should have the following characteristics:
1) to store as much energy as possible in a given volume to achieve a long operating range.
2) Have the lowest weight possible for reducing the burden on the transmission system.
3) Recharge quickly and easily.
4) Make or through charge and discharge cycles during the lifetime of the vehicle.

For an amateur builder to convert a car normal gasoline internal combustion, the nickel-zinc batteries can provide greater benefits. They are less expensive than lithium-ion battery of comparable size. Its energy density is about 70 watt-hours per kilogram, compared with 150 or more lithium-ion. On the other hand are easier to collect, whether by acceptance of a constant load on the system drive or the burden of constant current with minimized overhead. The metals used in nickel-zinc batteries do not present a problem of disposal of hazardous waste when the batteries need replacement, ibm t30 laptop battery and shows no lithium could cause a fire accident.
Some of the prices used to pay at the pump will be reflected on your electric bill when connected to electricity in their new car to recharge at home. Consider a small car like the MINI E, BMW Group will need about 30 kilowatt-hours of electricity to go 150 miles (240 km). Depending on where you live electricity rates, which can range from 7-18 cents per kilowatt-hour, this can cost between $ 2.10 to $ 5.40. Although this compares favorably with about $ 9 spent at the pump at an equivalent cost may change when they find a way to add in what was perceived tax on gasoline at the pumps. Do you have any idea how much it costs each year to mow the grass on a stretch of the interstate, or light traffic flow in a year? At this time, electricity costs are high in the Northeast and California, but low where there is an abundant supply of hydroelectric power. But that may change as public services deemed necessary to rebuild its power grid to support the growing demand for charging electric vehicles.
