Electric cars are designed to run by the use of a battery or 'electric' parts rather than from fuel like gasoline. Electric cars don't pollute like gasoline ones do so that makes them environmentally friendly. I believe in the future of electric cars. But there are some draw backs.
Ever since the early days of automobiles over a hundred years ago, electric cars have always been considered to be dull and boring. Oh sure an electric car was fine if you only had a short commute or had to shop lithium ion batterty stocks at the local grocery and couldn't get there by foot or bicycle. But they were slow, ugly and hardly more than glorified golf carts.
Nickel- Metal Hydride - Ni-MH batteries is considered to be the successor of the Ni-Cd batteries but unfortunately the dreaded memory effect is as bad as well. However as compared between Ni-Cd and NiMH batteries, the latter last longer as compared to its predecessor.
So how do they work? Well the all-electric cars both work in a similar way. The petrol/diesel tank is replaced by lots of batteries which provide the electric "fuel". There are three types of batteries lead-acid, nimh and li-lithium ion batterty stocks, with li-ion batteries storing the most energy in the least amount of space.
This is cobalt ontario canada the most basic of hand held power drills. It is a simple electric drill with one speed and one direction. It is mainly good for drilling holes in wood, metal, plastic, and soft metals. It is not the ideal choice of drill to use for applications such as driving screws. Since the speed is not variable and the drill only operates at a higher RPM, you would likely either strip the screw head or snap the head off the screw if you tried. You will not likely find many of these around today as their uses are rather limited.
The XM-5000Li is 100% electric and has a 5,000 watt rear hub motor, but still manages to be very lightweight because of it's lithium-ion batteries (thus the "Li" in the name), coming in at only 216 pounds total weight. Two can ride comfortably, since it can carry up to 400 pounds in payload.
Next time you get half an hour into a job, and your old Cordless Drill Driver runs out of juice again, think about getting your next cordless drill with Lithium ion batteries!
