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.

Existing chargers can be reused as is. The cost of replacing with a lithium-specific charger and the electrical work for installation will be reduced to "zero." A smooth transition utilizing existing infrastructure is possible. No modifications needed on the vehicle side (plug-in replacement). By customizing the shape and voltage to match existing lead batteries, operations can start simply by swapping them out without changing the circuit design on the vehicle side. Extending lifespan reduces the "number of replacements." With a cycle life more than three times that of lead batteries, future battery replacement costs can be significantly minimized. Support for small lots and shortest delivery times. Replacement can be done from just one unit. Instead of changing all vehicles at once, it is possible to first trial with one unit and then gradually proceed with lithium conversion according to your budget. "Fail-proof" implementation support through domestic in-house inspection. Vehicle specifications are checked in advance, and shipments are made with optimal settings. Hidden costs due to post-implementation troubles are thoroughly eliminated.
