Why can’t new energy vehicles imitate wireless charging of mobile phones?

In recent years, with the growing concerns about environmental pollution and the depletion of fossil fuels, there has been an increased focus on developing new energy vehicles as an alternative to traditional gasoline-powered cars. One of the promising technologies that has gained attention is wireless charging, which allows electronic devices, such as mobile phones, to charge without the need for physical connectors. However, despite the success of wireless charging in mobile phones, implementing this technology in new energy vehicles poses significant challenges.

Firstly, the power requirements for charging a mobile phone and a new energy vehicle are vastly different. A typical mobile phone battery has a capacity of around 3000-4000mAh, while the battery capacity of new energy vehicles ranges from tens to hundreds of kilowatt-hours. To charge a vehicle battery wirelessly, it would require a much larger amount of power, which poses technical difficulties in terms of efficiency and safety. The transfer of such high power wirelessly over a considerable distance may result in energy loss and potential safety hazards.

Secondly, the size and weight of the charging equipment play a crucial role. For wireless charging to be effective, the charging equipment needs to be compact and lightweight. This allows for easy installation in various locations, such as homes, offices, and public parking spaces. However, the size and weight of the charging equipment needed to wirelessly charge a new energy vehicle would be significantly larger compared to mobile phone chargers. This makes it challenging to integrate into the vehicle’s design and find suitable locations for installation.

Furthermore, the charging time for new energy vehicles is significantly longer than that of mobile phones. Currently, wireless charging for mobile phones takes a few hours to fully charge the device. However, new energy vehicles typically require several hours or even overnight charging to reach a full battery capacity. This prolonged charging time may not be practical for everyday use since it would restrict the mobility of the vehicle. Therefore, a more efficient charging method, such as direct plug-in charging or fast-charging stations, is preferred for new energy vehicles.

Another factor to consider is the cost associated with wireless charging technology. Implementing wireless charging infrastructure on a large scale would require substantial investments in research, development, and installation. Additionally, the cost of wireless charging equipment itself would be significantly higher than traditional plug-in chargers. These added expenses may deter widespread adoption of wireless charging for new energy vehicles, especially when there are already established and cost-effective charging solutions available.

In conclusion, while wireless charging has revolutionized the way we charge our mobile phones, it presents significant challenges when applied to new energy vehicles. The high power requirements, size and weight limitations, prolonged charging time, and cost considerations make it impractical to directly imitate wireless charging of mobile phones for new energy vehicles. However, advancements in technology and further research may pave the way for more efficient and practical wireless charging solutions in the future. Until then, plug-in charging and fast-charging stations remain the most viable options for charging new energy vehicles.
