Introduction

WPC initiated the Soft-Launch certification testing starting from November 2023. This phase primarily targets early participants in the polit testing (MPP Plugfest) and standard technical contributors. Products that pass the certification will serve as resources for Qi2 compatibility testing and set the benchmark for subsequent certifications.

CVSMicro, as a longstanding wireless charging chip company, has been dedicated to the development of related products and solutions for ten years. Following the commencement of Soft-Launch certification testing, CVSMicro actively participated and upheld high standards within the limited testing time, without compromising magnetism for coil testing.

On November 17th, at the TTA IOP testing conference in Korea, the CVSMicro CV222 module successfully passed the final test, scoring excellently in compatibility testing, achieving a 100% pass rate for Qi2 certification. It became one of the first few products to pass this certification, and certificates were issued on December 7th with the number 14732.

Since August 2022, CVSMicro actively engaged in the shaping and verification of the Qi2.0 (MPP) standard, participating in the plugfest events in Copenhagen in July 2023 and Seoul in September 2023. Each time, they left a profound impression with their high standards and high pass rates. Due to the early maturity of their solutions, they led the way in machine-to-machine testing and naturally took on the task of debugging machines.

The standardization and maturity of their solutions were fully demonstrated during the Qi2.0 certification process. The CV222 smoothly passed compliance certification with minimal time expenditure (approximately 1/6th of the time for some projects) and achieved full compatibility in one go. These advantages will continue to be evident in future certification projects.

CVSMicro CV222 Module

The CV222 primarily incorporates the CV90367 wireless charging chip as its core component, supporting multiple power specifications such as USB PD/QC 12V2A, 9V2.22A, 5V3A, and DC protocol 9V2.22A input, with a maximum 15W fast charge output. Its standby power is less than 300mW, with an efficiency exceeding 82%.

The CV222 supports BPP/PPDE/EPP/MPP protocols, featuring coil-to-PCB isolation design to minimize the impact of PCB heat on coils, resulting in faster charging among other advantages.

This is a close-up of the CVSMicro CV222 wireless module, approximately 58.2mm (2.29 inches) in diameter and 7.9mm (0.31 inches) thick.

Summary of ChargerLAB

CVSMicro's release of the CV222 Qi2 MPP wireless charging module easily passed the Soft-Launch certification testing initiated by WPC in November 2023, achieving a perfect score for Qi2 certification, becoming one of the few products to pass this certification. The CV222 adopts the CV90367 chip, supporting USB PD/QC, showcasing high efficiency, multi-protocol support, and comprehensive protection measures, with excellent temperature control.

Simultaneously, CVSMicro thoroughly considered and verified the CV222's circuit decoding ability, magnetic attraction, and ensured size specifications for Apple's original module interchangeability, exceeding 82% efficiency. It reduces system heat, adds heat-dissipating aluminum on the coil's backside, separates the PCB from the coil to minimize the PCB's heat impact on charging time, ensuring charging speed and a superior user experience.

As the demand for wireless charging grows with technological advancement, the demand for Qi2 wireless charging innovations increases. By utilizing CVSMicro's wireless charging modules, product design complexity can be simplified, costs can be reduced, providing the market with a novel and efficient wireless charging solution.
