Battery and System Health Monitoring of Battery Powered Smart Flow Meters Reference Design
Description
This reference design showcases innovative solutions for battery and system health monitoring of battery-powered Smart Flow Meters. The battery monitoring subsystem provides highly accurate energy measurement and State of Health(SOH) projections which forecast battery lifetime. The system monitoring subsystem protects against over current conditions which can dramatically reduce battery life. The techniques demonstrated here can help extend the effective life of battery-powered meters and optimize total cost of ownership for utility operators.
Features
- Monitors the State-Of-Health of non-rechargeable lithium batteries
- Accurately predicts the End-Of-Service of non-rechargeable lithium batteries
- Low power system monitoring with ADS7142 SAR ADC and LPV521 op-amp
- Single channel load switch to connect/disconnect system load
- Supports Lithium Thionyl Chloride (LiSOCl2) and Lithium Manganese Dioxide (LiMnO2)
- Low standby power consumption of 1uA for system health monitoring and 1uA for battery monitoring
Applications
- Water Meter
- Gas Meter
- Heat Meter
- Macro Remote Radio Unit (RRU)
- Active Antenna System mMIMO (AAS)
- Wired Communications
