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; the firmware is programmable using infrared
- 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 4100m altitude in Antarctica under -80°C 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
- Eliminating wiring and connectors, which are the major cause of failures
Successful applications
- Used by China’s astronomical observatories at Kunlun Station, Dome A, Antarctica.
Capabilities and facilities
- -80°C fridge for environmental testing
- Fault-tolerant software using low-power AVR microcontrollers
