電気自動車用バッテリー充電技術の動向-リチウムイオンバッテリー機器
2022年7月20日
Whether domestic or foreign, electrification is now a major trend in the development of the automotive industry. However, the development speed and penetration rate of electric vehicles are not satisfactory. When it comes to the bottleneck factor, the limitation of battery charging technology is inseparable. The editor will take you today to take a look at the new trends in this technology in the world.
Can battery charging technology limit overcharging and wireless charging to solve electric vehicle mileage anxiety?
According to reports, the TSLA recently made an upgrade to the power transmission capacity of the supercharger. At present, the output power of some supercharging stations in California has been increased from 135KW to 145KW. At the beginning of the establishment of the super charging station in 2012, it could only transmit power of 120KW, while the maximum charging power supported by the TSLA battery at that time was only 90KW. However, after synthesizing the output electric rate of the upgraded TSLA supercharging station and the charging capacity of the TSLA battery, the British Advertising Standards Association believes that the TSLA car is the fastest charging model among mass-produced electric vehicles. To understand, Model S and Model X can travel up to 273.6 kilometers after charging for half an hour, which is amazing when you think about it.(Lithium - Ion Battery Equipment)
Here is the upgrade of TSLA's super charging station, consolidating its leading position in the field of electric vehicle charging. On the other side, WiTricity has formed alliances with OEMs and component suppliers everywhere to promote its own wireless charging technology.
According to foreign media reports, using WiTricity's wireless charging technology, the output power can reach up to 11KW, and the charging efficiency has reached 94%. Although there is still a big gap compared to the super charging technology of TSLA145KW, it is a good result in the field of high-power wireless charging.
The deep cultivation in the field of wireless charging and the open attitude in other fields are the reasons for the rapid development of WiTricity. At present, the three major charging standards in the field of wireless charging, powerMat, A4Wp, and Qi, all use electromagnetic induction for power transmission. This technology has strict requirements on the transmission distance. However, the magnetic resonance technology used in WiTricity can realize long-distance power transmission and can charge multiple devices at the same time. It is worth mentioning that cars of different shapes, sizes, and types, from Mercedes-Benz Smart to modified trucks, and even common AGVs in factories can use WiTricity's magnetic resonance technology for wireless charging.
Just a few days ago, WiTricity and Delphi entered into a licensing agreement to supply automakers with commercial wireless charging technology. Earlier this year, EV battery suppliers CTEK and WiTricity signed a similar deal. Seeing this, the editor wants to ask: Do you still want to drag a long cable to charge your car in the future?
Not only are technology companies advancing in the field of electric vehicle charging, but the government is also sparing no effort in promoting electric vehicle technology. The Obama administration recently announced an approach to promoting electric vehicles. The approach has involved everything from shortening charging times to supplying more charging points, from electrifying government vehicles to hosting "electric vehicle hackathons." The most exciting promise, of course, is faster charging.
Can battery charging technology limit overcharging and wireless charging to solve electric vehicle mileage anxiety?
At present, TSLA's super charging network is already the fastest public charging device, with a charging power of up to 145KW, but imagine that if the charging power reaches 350KW, an electric vehicle with a cruising range of about 320 kilometers can be fully charged in just 10 minutes. The US domestic "Battery 500 Consortium" (Battery 500 Consortium) has made a cooler promise: keep battery costs at $100/kwh.
Although there is no specific new technology demonstration, it points out the direction for the development of electric vehicle charging technology in the future. This time, the promotion method proposed by the US government has shown great appeal. At present, 12 public utilities and charging companies have pledged to increase the deployment and charging infrastructure of electric vehicles, 35 new partners (commercial, non-profit organizations, Universities, Utilities) join the U.S. Department of Energy’s Workplace Charging Program, which will also host an Electric Vehicle Hackathon.
