Alkaline batteries for AGVs are very expensive. Due to the high replacement costs, some companies are considering discontinuing AGVs. What we propose this time is the activation of alkaline batteries. NiCd and NiMH batteries inevitably experience capacity reduction due to the effects of memory. Depending on the usage environment, cell degradation occurs after about four years. The activation treatment achieves capacity recovery, increased charge and discharge capability, and voltage stabilization. It also has cost-saving effects, making it very economical.

Old equipment still often uses NiCad and nickel-metal hydride battery packs. Some battery packs have already been discontinued, and the manufacturer can no longer provide them. This can be very troublesome when you want to continue using equipment that is still functional. If we can take possession of the actual item, it is possible to manufacture a replacement (new product). <Advantages of Replacement> 1. You can directly replace the existing product. (If it has lead wires or connectors, we can almost always make a proposal.) 2. The size and usability can remain the same, and we can also propose an increase in capacity. *Please note that there may be cases where we can only propose up to the same capacity. 3. If connector terminals for discontinued battery packs can be obtained, we can accommodate them. (We can also accommodate by reattaching existing connectors.) 4. There may be cost reductions compared to purchasing from the manufacturer.

To maximize the operational efficiency of automated guided vehicles (AGVs/AMRs), 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 associated 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 stops (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, including cycle life data and temperature rise evaluations during rapid charging. This equips your next-generation model with the powerful weapon of "rapid charging," shortening the time to market.
