Analysis: Electric Vehicle Battery Charging Technology New Trends!

Regardless of domestic or foreign, electricization is now a big trend in the development of the automotive industry. However, the development speed and penetration rate of electric vehicles is not satisfactory, and when it comes to the bottleneck factor, the limitations of battery charging technology can’t take off..

Xiaobian takes you today, there is any new movement of this technology.. Battery charging technology limited super charge and wireless charging, etc.

can solve the motor vehicle mileage anxiety? According to reports, recent TSLA has upgraded the power transmission capacity of the super charging station.. At present, some super charging stations in California have increased from 135KW to 145kW.

. At the beginning of the 2012 Super Charge Station, only 120kW electrical energy transmission, and the maximum charge power supported by TSLA batteries is only 90kW..

However, after a combined output electricity rate after the upgrade of TSLA and the TSLA battery’s charging capacity, the British Advertising Standards Association believes that TSLA cars is the fastest model of charging speed in electric vehicles.. To understand, Models and Modelx can reach 273.

6 kilometers after charging for half an hour, thinking that it feels magical. This is the upgrade of TSLA’s super charging station, consolidating his leading position in the field of electric vehicle charging..

The other side is Witricity to the OEM host factory, and the parts supplier alliance, and push their own wireless charging technology.. According to foreign media reports, using Witricity wireless charging technology, the output power can be up to 11KW, and the charging efficiency reaches 94%.

. Although there is still a big gap compared to TSLA145KW superchard, it is already a good result in the field of high-power wireless charging..

In the field of wireless charging, the open attitude in other fields is the reason for the rapid development of Witricity.. At present, the three major charging standards in the field of wireless charging standards POWERMAT, A4WP, QI are electromagnetic induction, which is more stringent for transmission distances.

. However, the magnetic resonance technology used by Witricity can realize long-distance power transmission, and can charge multiple devices at the same time..

It is worth mentioning that different shapes, sizes, different types of cars, from Mercedes-Benz Smart to modified trucks, and even common AGV cars, Witricity can be used for wireless charging.. Just a few days ago, Witricity and Delphi signed a licensing agreement to supply commercial wireless charging technologies for automake manufacturers.

. This year, electric car battery providers CTEK and Witricity also signed a similar agreement..

Seeing this, Xiaodeng asked: Do you still want to drag a long cable to charge your car? Not only is the technology company in the field of electric vehicle charging, but also the government in promoting electric automobile technology.. The Obama administration has recently announced a promotion method for electric vehicles.

. The method involves shortening the charging time to supply more charging piles, electricity from the government’s electric motor to the “electric car hacker marathon”, and the aspect form is a variety of activities..

Of course, the most exciting commitment is to improve the speed of fast charging.. Battery charging technology limited super charge and wireless charging, etc.

can solve the motor vehicle mileage anxiety? At present, the super charging network of TSLA is already the fastest public charging device. The charging power is as high as 145kW, but if the charging power reaches 350kW, then a battery life is about 320 kilometers of electric vehicles can be full for 10 minutes..

The US domestic “battery 500 community” (Battery500consortium) made a more cool commitment: control battery costs in $ 100 / kWh. Although there is no specific new technology display, the direction of the future electric vehicle charging technology. The promotion approach proposed by the US government has appeared a lot.

At present, there are already 12 public institutions and charging companies to commit new electric vehicles deployment and charging infrastructure, 35 new partners (commercial, non-profit organizations, University, public institutions) Join the “Workplace Charging Program” of the US Department of Energy, and will also host “electric cars hacker marathon”. This method of the White House is followed by STS (Sustainable Traffic Summit). STS is sponsored by the US Department of Energy, and this month is held in Washington this month.

. After the summit, about 50 companies and organizations signed the “Promoting Electric Automotive and Charges”. The Obama administration has never stopped in advising electric vehicles, including the proposal to add electric car buyers to $ 10,000, and in 2011, Obama expressed hopes that the number of electric vehicles on the road can reach 1 million.

While not reached, the government is still seeking new ways to achieve this goal in 2016.
