Tseetech 200W mid-power wireless power solution in mass production
In the last article, we explained why TE03 is indeed a state-of-the-art solution for medium power wireless charging. TE03 satisfies all the key advantages of applying contactless charging, convenient, safe, and robust.
Since we announced TE03 last December, we got several queries, and we picked up a reliable German e-scooter wireless charging system customer to cooperate with. To accommodate the customer's e-scooter parking dock design, we redesign the coils and apply the magnetic material from the customer, which is not easy for any wireless charging solution company for this customization. With the Tseetech team's tireless effort, we finally achieved the same performance as the original TE03 with this new design. The key advantages of this solution are:
1. High precision foreign object detection algorithm: The customer's parking dock charges the e-scooter from the bottom. Our solution makes the parking dock can detect metal objects as tiny as a coin. It ensures the safety of this parking dock no matter who the target user is.
2. High system end-to-end efficiency and low-temperature rise: We applied the customer's specific magnetic material in the new design. We successfully keep the whole system's end-end efficiency higher than 90% with our tuning. All the components on the control board are within 50 degrees temperature rise even at the maximum charging power ~200W.
3. Meet the EU EMC requirement EN55032 Class-B: EN55032 Class-B is a holy grail for wireless charging system EMC performance. Some wireless charging systems only passed the Class-A limit, so they can only be deployed in specific environments like factories or outdoor places. Tseetech solution meets the EN55032 class-B limit, so the customer's parking dock can be deployed anywhere to satisfy the rigid demands of lots of e-scooter users.
The new version of TE03 is now in mass production in Dongguan, China. They will be assembled in the customer's parking docks in Germany, and it's expected people can see them on the street by the end of May 2022. We hope our effort can make the world more convenient for electric two-wheelers and help many countries achieve their carbon emission reduction goals.
We look forward to your feedback.
