BMS-300
Battery Monitoring System for Commercial Trucks
BMS-300 Battery Monitoring System is designed specifically for commercial truck and fleet applications. It is installed in the truck permanently to measure battery capacity to help drivers and fleet managers avoid dead batteries in real time.
- Measures voltage, current, and temperature up to 1,000 times per second
- Provides CCA measurement of the system every time the vehicle starts, just like a tester
- Calculates battery state of charge and state of health
- Measures and reports lowest voltage and highest current during start events. Measures and reports current up to 3,000 amps to help users understand why voltage may be dropping or why vehicle is difficult to start
- All data reported through CAN J1939 messages
- Trending BMS values through telematics can help warn of potential no-start scenarios
- Sleep mode saves energy when truck is not in use
BMS-300 SELECTED FEATURES
- Low resistance, heavy duty shunt is suitable for starting circuits
- Sealed to IP6K9K rating for in-vehicle use
- Heavy duty truck rated sealed connector on a wiring harness makes connection easy and durable
- Electronic components sealed in plastic
- Chemical resistant construction
Battery Management Processes
Midtronics products are designed to meet a variety of battery and electrical system service requirements, but selected features on individual products may make them a better fit for your unique service applications. This product is particularly well-suited for these battery management processes:
Condition-Based Management
Service Diagnostics
Preventative Maintenance
Avoid No-Starts by monitoring battery, starter, and alternator data in real time
Increase time between service intervals. If BMS indicates strong batteries and low resistance, then no service is needed.
