To deliver an accurate preliminary technical proposal and pricing model, Telco’s application engineering team requires nine core technical inputs:
1. Nominal & Max System Voltage: (e.g., 48V, 96V, 400V, 800V DC bus)
2. Usable Energy Capacity: In Amp-hours (Ah) or Kilowatt-hours (kWh)
3. Continuous & Peak Discharge Current: Along with peak current duration (seconds)
4. Charge Strategy & C-Rate: Standard AC charging vs. High-power DC Fast Charging (DCFC)
5. Physical Envelope & Mass Limit: Maximum allowable dimensions (LxWxH in mm) and weight budget
6. Environmental Ratings: Operating temperature range and IP sealing level (IP65, IP67, IP69K)
7. Communication Protocols: CANbus (CANopen, SAE J1939), Modbus, or custom serial telematics
8. Compliance Requirements: UN 38.3, UL 2580, UL 1973, CE, or ECE R100 certifications
9. Production Volumes: Prototype phase quantity and anticipated annual mass-production forecast
