February 23, 2024, due toElectric bicycle15 people died when the battery charged and caught fire.Although a large number of outdoor shared charging sockets have been put into use in the past few years, they still cannot keep up with the demand because of the security risks of the mains power.
On the other hand, the outdoor safety risk is very high: because ordinary electric car chargers have cooling windows, water will enter in rainy days, which may lead to the direct connection between 220VAC and 48VDC on the circuit board, detonating the battery or causing a fire.
More importantly, the existing technology cannot accurately monitor the vehicle charging state and block the danger, so even if the vehicle is charged in the canopy, a fire will still occur.The picture below is taken next to the author last year.
On February 29, 2024, an online article "Guangxi will vigorously promote intelligent fire safety of electric two wheeled vehiclesWireless chargingThe news of "Technology" shows that the electric two wheeled vehicleWireless chargingFor the first time, the technology has been included in the list of solutions for fire safety of electric two wheeled vehicles by government units.
However, as long asWireless chargingIs the product safe?The following figure shows a 5V, 5W power supply consumerWireless chargingThe surface temperature of the wreckage after damage and fire is as high as 120 ℃.What if the voltage becomes 24V/48V/72V and the power increases to 100W/200W?
on the other hand,Electric bicycleIf the retail price is between 1500 and 2500 yuan, the market will accept the purchase price of hundreds or even thousands of yuanWireless chargingEquipment?
Even if customers are willing to bear the safety risks and high costs, where should the large and heavy red wireless charging receiver like the one shown in the figure below be installed in order to let every consumer enjoy a beautiful and convenient experience?
thereforehigh passAfter years of personal research, Mr. Chen Shengkuan, former Marketing Director of the Asia Pacific Wireless Charging Business Unit, specially invited Qitian Taiyi to launch the world's first 200W class based on its knowledge of EMC's patent system technology of separate architectureElectric bicycleWireless direct charging products.This series of products not only completely solve the security problem of the wireless charger, but also significantly improve the energy transmission efficiency of the system, and significantly reduce the cost and size on a year-on-year basis, making the wireless charging technology available for all-weather, all-scene, easy installationElectric bicycleMarket.(For EMC separated architecture technology, please refer to previous articles of the charging head network)
The following figure shows the separation of the circuit board and charging area of the EMC separated wireless charger.
In order to promote this product, Chen Shengkuan established "Jiaxing Runmeiqi New Energy Technology Co., Ltd." in Pinghu Monst Digital Industrial Park, Jiaxing City, to sell this EMC separated wireless charger named "WDC-TypeA-2023".Welcome interested friends to inquire, and you can email Chen Shengkuan to learn morejackchen@jasonspower.com
