ARICOM Company의 최신 혁신 기술인 손목형 레이저 치료 장치는 레이저 혈관 외부 방사선 요법을 사용합니다. 비강과 신체 표면의 국소 방사선 조사를 위해 설계되어 염증 감소, 통증 완화, 혈액 점도 감소 및 혈중 지질 수치 저하와 같은 보조 치료 효과를 제공합니다.
In the early stages, ARICOM encountered persistent issues with their battery suppliers. Problems such as batteries failing to charge and having short discharge times plagued the device, and these issues remained unsolved for an extended period. Eventually, ARICOM turned to Cowon Battery for a solution. With the active and close collaboration of Cowon's battery engineers, these battery-related problems were effectively resolved, significantly enhancing the device's performance and reliability.
문제 해결 접근법
아리콤의 고장난 레이저 치료기를 받은 코원은 문제의 원인을 정확히 파악하기 위해 정밀 분석을 실시했습니다. 그들은 배터리가 충전되지 않고 방전 시간이 짧은 이유를 파악한 다음 단계별 솔루션을 개발했습니다.
1.Charging Issue: The primary reason the battery couldn't charge was due to over-discharge, which caused the battery to deplete completely and trigger low-voltage protection. This mechanism prevents the battery from charging further to avoid excessive damage.
Solution: Cowon's battery engineers conducted a series of comprehensive tests and determined that the original IC's over-discharge protection voltage was too low. They replaced it with an IC featuring a higher over-discharge protection voltage. Additionally, they calibrated the battery management system (BMS) to better handle low-voltage conditions, ensuring the battery could recover from over-discharge situations. This adjustment successfully resolved the charging issue, allowing the battery to charge efficiently even after deep discharge.
2.Short Discharge Time: The short discharge time was due to sev
