In outdoor, tunnel, pipe gallery, and extreme production environments, high or low environmental temperatures pose a severe challenge to the reliability of wireless charging solutions.
In outdoor, tunnel, pipe gallery, and extreme production environments, high or low environmental temperatures pose a severe challenge to the reliability of wireless charging solutions.
If the working environment temperature is too high, the efficiency and heat dissipation design of the corresponding wireless charging scheme should be more reasonable and reliable. If the efficiency is low, the heat dissipation is not good, and the over temperature protection design is unreasonable, it can easily lead to substandard charging power, frequent restarts, and even inability to charge normally.
In environments below 0 ℃, the electrical performance, insulation ability, thermal stability, and mechanical characteristics of components will deteriorate. Wireless charging solutions using low temperature resistant and low-cost components often experience downtime, no response when powered on, and other phenomena in low temperature environments, making it impossible to charge normally.
Magnetic Trace Technology's wireless charging solution products are exported more often, and the after-sales cost for quality problems in export business is generally higher. So the principle of component selection and quality control of Magnetic Trace Technology is to avoid quality problems, reduce and even avoid after-sales service. The selected components meet the requirements of export certification in terms of high and low temperature performance. Combined with Magnetic Trace's own precision algorithm, wireless charging solution products have good high and low temperature reliability performance, while also having a reliable over temperature protection mechanism, which can meet the stable and safe charging requirements in an environment temperature of -20 ℃ -55 ℃.
In addition to the reliability difference indicators mentioned above, the selection of wireless charging solutions also needs to consider whether the basic parameters such as charging voltage, current, distance, and size match, the charging efficiency is high or low, especially the stability of the output (voltage/current ripple), whether various protection mechanisms such as overvoltage, overcurrent, no-load, and short circuit are complete.
