The electric vehicle (E.V) is expected to become popular worldwide. However, Japan doesn’t even own 1% of the E.V industry. One of the main reasons for this is the waiting time to charge the battery. Nissan Leaf, Japan’s top-selling E.V with high-speed charging still takes 40 minutes to reach 80%.
However, a surprising method in China that only takes 2 minutes to charge is becoming popular.
Changing the entire battery!
As a measure to reduce pollution In China’s larger cities, plans are being made to spread the use of electric vehicles. In Hangzhou, a city located one hour from Shanghai, you can already see this new type of charging stations scattered around the city centre.
With a compact size and a subsidiary-included price of 1,300,000 yen (£8600), the car which is made by a Chinese motor vehicle known as SKIO is being used by taxi services. The main feature of this car is the special method by which you recharge the car.
There is no cable or waiting when charging this car!
Instead, you swap the battery which has run out of charge for a battery that has previously been fully charged. This is called the ‘removable battery method’.
The batter has a long and flat shape that is stowed away beneath the car. When a car needs the battery replaced, a manually operated machine will take out the battery from beneath the car door and replace it with a fully charged one. This procedure takes less than 2 minutes.
In each station, there are over 100 batteries being stored and charged. When a car comes, the computer selects a battery that has been fully charged and carries it to the car. Around 200 people a day visit each station to replace their battery.
This new type of E.V was implemented one year ago and around one million cars were sold in the city of Hangzhou.
Longer battery lifespan!
For a standard electric car, one must replace the battery every three years, but with this new method, it only needs replacing once every five years. The company hopes that this new charging method will become popular with taxis, trucks, and car-sharing services.
