苦境
アリコム社の最新イノベーションである手首型レーザー治療器は、レーザー血管外照射療法を利用しています。鼻腔や体表面に局所的に照射するために設計されており、炎症の軽減、痛みの緩和、血液粘度の低下、血中脂質レベルの低下などの補助的な治療効果を提供します。
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.
問題解決型アプローチ
アリコムのレーザー治療器の故障を受けて、Cowon氏は詳細な分析を行い、問題の原因を突き止めました。彼らは、バッテリーが充電できないことと放電時間が短い理由を特定し、段階的な解決策を開発しました。
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
