Murata announces mass production of a FORTELION 24V battery module for industrial equipment
Murata Manufacturing Co., Ltd. has developed a FORTELION 24V Battery Module (all-in-one type) that is designed for industrial equipment requiring high output, such as automated guided vehicles (AGVs), robots, and electric forklifts. Mass production starts in April 2020. This module is equipped with FORTELION, the company’s proprietary lithium-ion secondary battery, which uses olivine-type lithium iron phosphate as the cathode material and is said to combine long life with a high level of safety.
According to the company, highlights of the product include:
- Size compatible with lead-acid batteries. Many service robots, AGVs, and electric forklifts have power systems operating on voltage multiples of 24V, so it is common to connect two lead-acid batteries each with an output voltage of 12V in series. The FORTELION 24V battery module is structured as a 24V system in a single battery management unit (BMS). Because the module is equivalent in size to a conventional lead-acid battery, replacement is easy.
- Dustproof and waterproof. The module has an IP54 rating, delivering protection against dust and water, and also meets the UL2271 safety requirement for batteries for light electric vehicles, so it is safe for outdoor use.
- Accurate remaining capacity calculation. The battery’s remaining capacity via CAN communication is accurately indicated as percentage (%) using its arithmetic processing technology based on the company’s knowhow developed with PCs, mobile phones, and other electronic devices.
The company says highlights of FORTELION include:
- Highly safe. Thanks to the stable crystalline structure made possible by employing olivine-type lithium iron phosphate (lithium ferrophosphate) as the cathode material, it is less vulnerable to breakage and less likely to catch fire, even if subjected to a large impact or significant pressure, and maintains a reliable battery performance even under intense workloads.
- Long life. Designed to undergo more than 10,000 charge-discharge cycles, it provides a much longer expected operating life than lead-acid batteries that typically require replacement around 500 cycles or regular lithium-ion secondary batteries that are capable of 2000 to 3000 cycles.
- Fast charging. It can be charged to 90% of its full capacity in about one hour, allowing devices equipped with this battery to be charged during standby mode.
- Excellent discharge characteristics. Less susceptible to voltage effects, it can be used for long periods and is also free from the memory effect observed in nickel-cadmium batteries caused by repeated partial discharge events.
