Why use Leclanché battery systems in AGVs and AUVs applications

Benefits of AGVs and AUVs


Automated Guided Vehicles (AGVs)

AGVs are operated to transport components of all sizes along production lines as well as logistics centers. AGVs are fully automated, operating 24 hours a day and do not require any human intervention since they are controlled by a sophisticated management software. The AGV will automatically return to the docking station to refill the battery. To ensure the efficient operation of the production line, the robustness and reliability of the robot are fundamental.

Thanks to LTO (lithium titanate) batteries, the AGV can be charged extremely fast, usually in less than 5 minutes. An equivalent lead acid battery solution would require 8 hours to be fully charged, a dedicated ventilated room and a significant maintenance cost to refill battery with distilled water making automatic operation impossible.

Benefits

  • Robots’ downtime is dramatically reduced. Less robots are required for the same level of service, improving the CAPEX model.
  • Compared to lead acid battery, the LTO battery has much higher round-trip efficiency. The electricity consumption is therefore reduced by 10-20%.
  • As the charging time is extremely short (under 5 minutes), the chargers have higher availability and can be shared to address a complete fleet of battery/robots.
  • The LTO battery does not require any maintenance, other than occasional dust cleaning. The LTO battery is gas free emission unlike the lead acid battery.

Autonomous Underwater Vehicles (AUVs)

AUV are high technology drones intended to localise, identify and destroy mines. The battery is the unique source of power, which energises the propeller as well as the imbedded controllers and sensors. To keep enough operational range, the battery energy density is key. The particular form factor makes the battery design challenging to balance energy requirement and power density.
