Li-Ion Battery Testing
Research – Design – Reliability – Manufacturing
From consumer goods to military applications, many of today’s technologies rely on lithium-ion (Li-Ion) batteries as an power source. Bloomy Controls provides fully automated battery performance and characterization test systems; we give our customers the tools to bring Li-Ion battery cells and packs to market faster, and with confidence. Our test systems are built with commercial off the shelf (COTS) hardware, including National Instruments measurement hardware, allowing for a significant reduction in lead-time compared with traditional battery test systems.
Hardware Flexibility
Batteries range in size and specifications, from coin cells to large packs. A test system can quickly be customized for specific product testing needs. Some options include:
- Voltage ranges: 0 to 600V
- Current ranges: 0 to 100A
- Measurement resolution: 16 to 24 bit
- 0 to 200 channels (dependent on overall system power)
- CAN, I2C, and SMBus communications
- Temperature and strain gauge monitoring
- Flexibility to integrate with other sensors
Battery Charge & Discharge
The application can run standard or custom battery charge and discharge profiles with the following modes of operation:
- Constant current
- Constant voltage
- Constant power
- Constant resistance (Amps/Volt)
- Taper current charging
- Pulsed charging
- Reflex charging
- Custom algorithms available
Test and Monitoring
The application allows for independent channel monitoring and testing with the following features (features vary from cell testing to pack testing):
- Available Test / Monitoring points:
- Open circuit voltage
- Closed circuit voltage
- Return voltage and time
- Channel current
- Internal resistance / ESR
- Cell matching and balancing
- Custom tests available
- Simulate real world power profiles
- Variable Charge / Discharge Profiles
- Life Cycle testing
- Simultaneous sampling up to 50 kS/s/ch
- High impedance Kelvin connections
- Appropriate system isolation (power specific)

"As always, Bloomy Controls did an outstanding job on our project. You
do an excellent job not only working on the projects themselves but
also collaborating with our other partners that are creating production
equipment for us. I look forward to working with Bloomy Controls in the
future to help us move forward in the production of our products."
