This article will introduce four leading wireless charging concept stocks and discuss their development prospects and market impact. Company A: A leading provider of wireless charging technology Company A is a company focused on the development and supply of wireless charging technology.
What are the wireless charging concept stocks? Qingdao Haier (600690) : Haier "tailless TV" adopts the wireless power transmission technology cooperated with MIT, which can transmit power to the TV without the help of wires, which is the first time that wireless power transmission technology has been successfully applied to the TV receiving terminal.
Slow charging (conventional charging, on-board charging) is suitable for on-board chargers and family wall-mounted charging piles, whose current and power are relatively small, and the general charging time takes 6-8 hours. Fast charging (ground charging, emergency charging) includes two forms of charging station and mobile supplementary trolley, mainly through the non-on-board charger using high current to directly charge the battery, so that the battery in a short timeThe inside can be charged to about 80% of the electricity, generally 1 hour can be fully charged.
For the protection of AC slow filling pile in electric vehicle charging station, different specifications of current limiting protectors can be selected according to different power. For 5kW slow filling pile, ASCP200-20D can be used; for 7kW slow filling pile, ASCP200-40B can be used; for 14kW double gun slow filling pile, ASCP200-40B can be used. You can use ASCP200-63D.
Yulongwan District. Dalian is located at the southern end of Liaodong Peninsula, at the junction of the Yellow Sea and the Bohai Sea, facing Shandong Province across the sea. It's ChinaAn important coastal business city, known as the "romantic city" title. According to public comments, Dalian Yulongwan community has electric bicycle charging piles. Dalian is the city with the least typical northeast characteristics.
Dalian City electric vehicle charging station, Dalian Ganjingzi electric vehicle charging station and North China Power Grid Co., Ltd. Tangshan Nanhu electric vehicle charging station project. Electric vehicle battery manufacturers: Shenzhen Lei Tian, Luoyang Sky, Tianjin Lishen, Zhejiang Tieneng, BYD (self-produced, which also produces charging piles with their own production of electric vehicles), Xiangfan Qingshan, CITIC Guoan, Peking University first, Beijing Tianlu, SuzhouStar constant, universal.
But the advantages of wireless charging are also very obvious. Because there is no need to plug and unplug the charging gun, it is convenient to chargeThe increase is obvious, and the risk of electric shock is reduced. More importantly, if dynamic wireless charging mode is deployed, it can greatly reduce the amount of battery power carried by electric vehicles, reduce the cost of the vehicle, and completely solve the user's driving range anxiety.
Secondly, wireless charging technology wants to be truly popular, and it also has high requirements for the precise positioning and intelligence of vehicles. Only when the vehicle is precisely parked in the charging space can the ground system establish a channel with the vehicle's on-board system and achieve charging. In the case of accurate positioning, the footprint is the same, and the number of electric vehicles using wireless charging is charged with traditional charging pilesThe electricity comparison will be greatly improved, greatly improving the space utilization rate and charging efficiency.
Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. High-power wireless charging High-power wireless charging usually adopts a resonant mode (most electric vehicle charging in this way) by the power supply device (charger) to transmit energy to the electric device, the device uses the received energy to charge the battery, and at the same time for its own operation.
For example, the automatic replenishment of the vehicle after the Tesla model starts FSD and arrives at the destination Dalian Automobile Wireless charging Solution manufacturer ; Unmanned buses, express vehicles, etc., can also be completely unmanned management; Or you do not have time to find a charging pile for your car, you can send the vehicle to find its own wireless charging pile "foraging"; Wireless charging can also solve the problem that many vehicles do not share charging plugs at present, just like mobile phones, cars, SUVsDifferent types of vehicles of different brands such as trucks can be charged using the same charging plate.
First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through special electromagnetic fields, allowing Tesla cars to charge themselves when parked. This technology is not only efficient, but can also greatly reduce charging time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence.
According to media reports, Tesla recently launched a $300 "wireless charging platform" that can charge up to three devices simultaneously. thisThe wireless charging pad can provide up to 15 watts of charging power for each device that supports the Qi wireless charging protocol, including iPhone, Android or AirPods headphones. According to Tesla's official website, the charging pad has been opened for pre-sale and will begin shipping in February 2023.And the charging mode equipment cost is low, so it is very suitable for family scenes as a private charging pile to charge the car. Disadvantages : Due to the small charging power of AC charging pile, the efficiency is low and the charging time is lowIt takes about 5-8 hours, and the longest even takes more than 30 hours.
Power change, is a direct replacement of the battery pack charging mode. When the power battery runs out, it can be replaced with a fully charged battery pack, which can greatly shorten the charging time. The replaced battery will be slowly recharged at the charging station. Wireless charging is a way of charging without connecting wires or cables. New energy vehicles can be charged automatically by simply parking on the wireless power board.
