To maximize the operational efficiency of automated guided vehicles (AGV/AMR), reducing charging time is essential. Our company offers the development and manufacturing of high-output lithium-ion battery packs that support rapid charging with high current. ■ Cell selection and thermal design based on "topping up" charging The biggest issue with rapid charging is "heat generation." In addition to selecting high-output cells with extremely low internal resistance, we design pack structures that pursue heat dissipation efficiency. This minimizes degradation due to heat and enables full-time operation through "topping up" charging during brief stop times (breaks or loading times). ■ Customization of dedicated BMS (protection circuit) for high current To ensure safety during rapid charging, we equip our systems with a dedicated BMS that features high-precision state of charge (SOC) monitoring and temperature management functions. We closely collaborate with manufacturers' charging systems to achieve optimal control of current and voltage values (such as CAN/RS485 communication). ■ Reliable data provision to reduce evaluation workload We provide essential evidence for manufacturers' product development, such as cycle life data during rapid charging and temperature rise evaluations. This equips your next-generation model with the powerful weapon of "rapid charging," shortening the time to market.

Lithium conversion with the charger as is. It is possible to replace existing lead-acid battery chargers with lithium ones. This significantly reduces the introduction costs. Achieving 24-hour operation with "topping up" charging. Short-duration topping up charging, which was strictly prohibited for lead-acid batteries, is now possible. This allows for recovery during brief breaks, minimizing the downtime of AGVs. Upgrade options for non-contact and rapid charging are also available. For sites aiming for further automation, we also offer customization for integration with non-contact power supply systems and rapid charging specifications. Maintenance labor reduced by 90%. No need for water replenishment or management of distilled water. The risk of floor corrosion due to battery liquid leaks is eliminated, maintaining a clean warehouse environment.
