与传统有线充电相比，无线充电具有无需插拔、无需物理联系我们、安全性高、维护成本低、环境适应性强等优点。在中大功率行业的应用已成为共识。然而，在行业应用过程中，由于各品牌无线充电解决方案的可靠性参差不齐，导致许多行业客户落入陷阱，增加了大量售后维护成本。总之，一种表现是他们经常不能充电。不能充电的原因多种多样，那么在选择产品应用时，无线充电解决方案的性能有哪些要注意和避免陷阱呢？我们将分三部分详细讨论。
Compared to traditional wired charging, wireless charging has advantages such as no need for plugging and unplugging, no physical contact, high safety, low maintenance costs, and strong environmental adaptability. The application in the medium and high-power industry has become a consensus. However, in the process of industry application, due to the uneven reliability of wireless charging solutions from various brands, many industry customers have fallen into the trap, increasing a lot of after-sales maintenance costs. In summary, one manifestation is that they often cannot charge. There are various reasons why it cannot be charged, so when selecting product applications, what are the performance of wireless charging solutions to pay attention to and avoid pitfalls? We will discuss in detail in three installments.
This issue discusses the selection of wireless charging solutions:
1. Communication reliability
无线充电方案的发射和接收部分是非联系我们的，充电状态的建立、停止、输出调整、安全保护、异常反馈和处理都需要这两部分之间进行无线通信。市场上的大多数无线充电解决方案都使用外部2.4G模块进行通信。无线通信频段的规定在不同的国家和地区有所不同。2.4GHz作为全球最常用的ISM频段，广泛应用于WiFi、蓝牙等通信协议中。它也是市场上用于带外无线充电解决方案的最常见的通信频带。但是，由于其广泛使用，它在复杂的环境中非常容易受到干扰，并且可能会干扰其他2.4G频段的设备。通常，如果无线充电工作环境中存在大量的WiFi、蓝牙等通信设备，则使用2.4G带外通信的无线充电方案容易受到干扰，导致无法充电或容易断开充电等问题。特别是一些厂商为了降低成本，纷纷采用高性能的2.4芯片，导致这一问题尤为突出。
The wireless charging scheme of Magnetic Trace Technology below 300W adopts carrier band communication as the communication method, which has advantages such as low cost, stable communication, and low interference. Simply put, it means that both the transmitting coil and the receiving coil can communicate and transmit energy, effectively avoiding the environmental interference problem of 2.4G communication mode and ensuring the reliability of charging.
For wireless power supply application scenarios with higher power, faster startup speed requirements, and frequent load changes, the advantage of carrier communication is weakened. Magneto Technology has also launched a wireless charging scheme based on 2.4G communication. However, to ensure communication reliability, on the basis of reliable selection of 2.4G chips, industry-leading autonomous frequency hopping software algorithms are adopted when facing interference, which can also ensure stable and reliable communication.
