According to VentureBeat, electric car owners are proud to say they no longer have to go to gas stations and use gas guns to fuel their car. But most of them would also think that it would be better to recharge the car without the need for wires and charging connections.
If Nissan and several other car makers succeed, that day will come because wireless (inductive) charging systems and smart charging control systems will allow users to give hands-free access if they park their electric car near the charging system Car charging.
VentureBeat said that over the years, Nissan has been developing wireless charging technology. The charging system supplier Bosch even offers a wireless charging system that can be installed on the garage floor.
For high-capacity battery more powerful charging technology
Induction charging systems previously offered by carmakers have slightly less than 3 kilowatts of power. However, an executive at the Nissan Technical Center in Atsugi, Japan, said "3kW of power is not high enough so we are developing a more powerful wireless charging system."
Nissan is currently developing a wireless charging system with a power rating of about 7 kilowatts. Such a system can easily be used to fully charge larger capacity batteries overnight. For example, Nissan is developing a 200 mile (322 km) Battery capacity of 60 kwh.
Wireless charging systems currently under development have become more flexible, and industry executives say vehicles can park up to 4 inches (10 centimeters) away from the "target eye" for wireless charging before, after, left and right.
VentureBeat said the latest wireless charging system developed by Nissan can bring the charging board to a distance of about 4-6 inches (10-15 cm), which is less than 4 inches in the previous 3 kW charging system.
This is a more natural altitude for a normal passenger car so that the transmission unit can be installed in a charging board that is flush with the ground and the receiving unit can be installed in a charging board located in the tail section of the car body, Does not affect the normal ground clearance. In the future, Nissan hopes to increase the distance between the charging pad and the car to more than 6 inches, which will be more suitable for cross-border vehicles.
In addition, the Nissan's new charging system is 85% efficient or higher - a fairly high figure compared to some of the previous inductive charging systems.
VentureBeat said Nissan will begin testing the new system this year and hopes to convince other automakers to adopt the same standard in the coming years. Such a system will not be massively deployed until the next decade. The project leaders and others are convinced of the need for standardization and Nissan expects to share its technology with other vendors at the right time. They think that the industry can not have another CHAdeMO and Combo (Level3 fast charging technology two standards), they are correct.
As a result, users will also need to deal with the charger cable for many years to come. They also need to find suitable charging interfaces and fantastically cleaner wireless charging future.
Zinc phosphate is a new type of nontoxic and harmless white antirust pigment with excellent performance in rust prevention and ideal application effect. It is the best substitute of conventional antirust pigments containing heavy metals such as lead and chrome.
Zinc phosphate is widely used in various coating materials for preparation of waterproof, ACID-resistant or corrosion preventive coating materials
