LiFePO4 Battery Management System
A wireless battery management system for LiFePO4 batteries capable of surviving cold-soaking at -80oC , with proven performance in Antarctica . |
Competitive Advantage • An innovative battery management system that :
• Has zero wiring
• Uses infrared for communication
• Allows hundreds of cells to be queried in seconds
• Contains one node per cell with infrared programmable firmware
• Can program multiple nodes in parallel , from any single node
• Completely separates digital and analogue sections for redundancy
• Has a large current capacity for charge balancing
• Is proven to survive altitudes of 4,100 metres in Antarctica in -80oC conditions
Impact • Developed for use in Antarctica where reliability and low-temperature survivability are critical , and where untrained operators need to be able to replace cells easily
