how electric car batteries work - battery power storage

The most obvious advantage of electric vehicle batteries is that they do not produce pollution related to internal combustion engines.
However, they still have environmental costs.
The electricity used to charge electric vehicle batteries must come from somewhere, and now most of it is generated by burning fossil fuels.
Of course, there will be pollution.
But, compared to the pollution generated by the internal combustion engine, how is the pollution caused by burning fossil fuels to charge electric vehicle batteries?
According to the Canadian Association of electric vehicles (EVAC), even electric vehicles that charge with coal
Electric generators cut carbon emissions by about half.
Electric vehicles are charged from cleaner forms of power generation such as hydropower and nuclear power plants, which can reduce carbon emissions to less than 1% of the carbon emissions generated by the current internal combustion engine.
So even in the worst case, electric car batteries operate cars that are cleaner than gasolinepowered cars.
Another important advantage of batteries
Gas drive motor-
Lower fuel cost for power engines-
That is to say, the electricity of electric vehicles and the gas of internal combustion engines.
The US Department of Energy calculates that a typical electric vehicle can travel 43 miles at a dollar.
Gasoline can only be produced if the cost of gasoline drops sharply
There are power cars anywhere near such a low cost per mile.
Another advantage of these rechargeable batteries is good recycling.
Almost 100% of these batteries can be recycled, which makes old batteries not a problem to deal.
Main disadvantages of the battery-
As we mentioned in the previous section, electric cars are the time it takes to charge the battery. With lithium-
Ion battery technology, a fully charged electric car can travel at a distance equivalent to a gas-filled internal combustion engine car, but at the end of that time it still needs to be placed on the charger.
Currently, this means that exhausted electric vehicles will stop using for a few hours before they are fully charged.
This is, of course, a serious shortcoming.
In the future, charging technology may be faster, but in the short term, electric vehicles will not become the first choice for long-distance travel.
Nevertheless, most of the driving is done in places close to home, so battery power is as effective as gasoline power.
The possible solution to the charging situation may be the battery-
Replace the station, where you can simply change the exhausted battery to a fully charged one instead of charging your electric car.
The system will allow the battery to be charged outside the vehicle and will greatly reduce the time it takes for the electric vehicle to restart and run after the battery is fully discharged.
Another drawback of electric car batteries is their weight.
Because electric car batteries need to do more than traditional car batteries, it is necessary to connect electric car batteries to an array or battery pack to provide additional power.
The battery collection is heavy. The lithium-
The ion battery pack in the Tesla sports car weighs about 1,000 pounds (453. 6 kg).
This is a lot of weight, it can greatly reduce the range of cars.
However, the designer of the sports car offset the battery weight with a light frame and body panel.
The whole car is only 2,690 pounds (1220. 2 kg)--
It's not too heavy when you think the battery is more than the third weight.
Given the importance of the battery to an electric vehicle, you may want to know what happens with the aging of the battery.
How long can it power the car?
Can it be replaced when it finally dies? Or is it more economical to buy a new car?
