Advantages and Disadvantages of EVs

The most advantage of electric car batteries is they don’t produce the associated with internal engines. However, they have environmental costs. The used to recharge EV batteries has to from somewhere, and right most electricity is generated by fossil fuels. Of course, produces pollution. But how does the produced by burning fossil to recharge electric car batteries to the pollution produced by internal engines?

According to the Electric Association of Canada, or EVAC, EVs recharged from coal-powered generators cut carbon emission in half. EVs recharged from forms of electrical power such as hydropower and nuclear can reduce carbon emissions to than one percent of those produced by internal combustion So, even in the worst case cars operated by EV batteries are than gas-powered cars.

It seems batteries are a practical way of powering a What are the advantages and disadvantages?

important advantage of battery-powered over gas-powered engines is the cost of the fuel — is, electricity for EVs and gas for the internal combustion The United States Department of has calculated that a typical EV can run for 43 on a dollar’s worth of electricity. a substantial drop in the cost of could give gas-powered anywhere near such a low per mile.

Yet another advantage of these batteries is that they well. Almost 100 percent of batteries can be recycled, which old batteries from becoming a problem.

The major disadvantage of cars, as we mentioned in the last is the time required to recharge the With lithium-ion battery a fully charged EV can travel a comparable to an internal combustion vehicle with a full of gas, but it still needs to be on a recharger at the end of that time. At this means a drained EV be out of service for several hours it’s fully recharged.

Of course, this is a serious In the future, faster recharging may become available, but in the near electric cars won’t be the of choice for long trips. so, most driving is done close to home and for this battery power will as well as gasoline power. A solution to the recharging situation may be stations, where instead of your EV you can simply swap drained battery for a fully one.

This system would batteries to be recharged outside of and would greatly reduce the of time required to get an EV up and running after its battery is fully

Another disadvantage of electric car is their weight. Because need to do more than car batteries, electric car batteries to be linked together into or battery packs, to provide power. These collections of are heavy. The lithium-ion battery in a Tesla Roadster weighs 1,000 pounds (453.6 That’s a lot of weight to carry and it can reduce the car’s range.

However, the designers of the Roadster offset this battery with a light frame and panels. The entire car only 2,690 pounds (1220.2 kg) not terribly heavy when you that more than a of that weight is battery.

the importance of the battery to an electric you might wonder what happen as that battery older. How long will it be to power the car? And when it dies, can it be replaced or is it simply economical to buy a new car?

Read on to find out.
