Project : to design Battery charger and BMS(Battery management system)
Existing Battery Configuration
2 × 12V, 100Ah Sealed Lead Acid (SLA/VRLA) batteries connected in series (24V DC system)
Scope of Work
We require a production-ready solution comprising an intelligent battery charger and BMS for continuous industrial operation.
Battery Charger (Intelligent 24V SLA battery charger)
1. Automatic Bulk, Absorption & Float charging
2. Configurable charging current
3. Temperature-compensated charging
4. Over-voltage, over-current and short-circuit protection
5. Reverse polarity protection
6. High efficiency design suitable for 24×7 operation
Battery Monitoring & Protection
1. Individual battery voltage monitoring
2. Total battery bank voltage monitoring
3. Charge and discharge current monitoring
4. Battery temperature monitoring
5. Battery health (SOH) estimation
6. State of Charge (SOC) estimation
7. Remaining backup time estimation
8. AC mains failure detection
9. Charger health monitoring
10. Battery fuse monitoring
11. Low battery alarm
12. Deep discharge protection
13. Battery replacement indication
14. Battery disconnect protection
Communication & Integration
1. RS485 / Modbus RTU
2. CAN Bus (Optional)
3. Ethernet Interface
4. SNMP (Optional)
5. Dry Contact Outputs
6. Alarm Relay Outputs
7. Cloud monitoring capability
8. Remote firmware update (OTA)
9. Integration with the Decibel Web Portal and Android Application
10. API support for third-party integration (preferred)
Deliverables
1. Complete schematic design
2. PCB layout
3. Gerber files
4. Bill of Materials (BOM)
5. Pick & Place files
6. Firmware and complete source code
7. Test reports
8. Manufacturing documentation
9. Production support
