La situation difficile

L’appareil de thérapie laser de type poignet, la dernière innovation de la société ARICOM, utilise la radiothérapie externe vasculaire au laser. Il est conçu pour l’irradiation locale de la cavité nasale et de la surface du corps, fournissant des effets thérapeutiques auxiliaires tels que la réduction de l’inflammation, le soulagement de la douleur, la diminution de la viscosité du sang et la réduction des taux de lipides sanguins.
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.

Approche de résolution de problèmes

Après avoir reçu l’appareil de thérapie laser défectueux d’ARICOM, Cowon a effectué une analyse détaillée pour identifier les causes des problèmes. Ils ont identifié les raisons de l’incapacité de la batterie à se charger et de son court temps de décharge, puis ont développé une solution étape par étape.
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
