[Case Study of Lithium for Forklifts] Operational Verification Example in a Cold Storage Warehouse
Introducing a verification example that concluded a single battery can operate for up to approximately 20 hours!
"Is it possible for a single lithium-ion battery to operate for 24 hours?" "Will it become unable to charge due to temperatures dropping below 0°C at the charging location, which has a lot of frozen cargo?" We conducted an investigation on these matters. The operating time per day was approximately 16.5 hours, with a charging time of about 4 hours and an idle time of around 3 hours, resulting in a discharge capacity of about 80% of 280Ah, with two cycles of operation (450Ah). As a result of the investigation, it was concluded that it is "possible" for one battery to operate for 24 hours, with a maximum operational time of about 20 hours. [Customer Overview] ■ Operating Location: -25°C cold storage ■ Lithium-ion Battery: 280Ah 48V - Operating Temperature: -30°C to 55°C - Charging Temperature: 0°C to 55°C ■ Fast Charger: 150A ■ Charger Installation Location: 0°C location *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Conclusion】 ■ It is "possible" for one battery to operate for 24 hours. ■ It can operate for up to about 20 hours. ■ The battery temperature during charging will not drop below 0°C if charged immediately after use. ■ If left alone, the temperature will continue to drop, but if charged, it can be used at temperatures as low as -30°C. ■ By improving the operability of charging, charging time can be further increased. ■ The necessity of having a 300A charger relates to the compatibility with electrical equipment (which requires 60A), but it would be beneficial to have. *For more details, please refer to the PDF document or feel free to contact us.
