1. Start with the vehicle interface
Provide the vehicle voltage range, motor power, controller limits, available battery space, connector drawing and locking method. These inputs establish the mechanical and electrical boundary for the battery.
2. Build the battery specification
Define voltage, capacity, cell chemistry, dimensions, weight target, enclosure, connector, ingress protection target and expected operating temperature. The acceptance criteria should also state the required cycle-life test conditions instead of using an isolated cycle number.
3. Confirm BMS and communication compatibility
Document the BMS functions, communication protocol, message definition, authentication requirement and fault handling. Cabinet charging logic and platform data depend on this interface.
- Battery identification and state-of-charge data
- Temperature, voltage and current monitoring
- Charge enable, stop and fault logic
- Remote diagnostics and update requirements
4. Match the cabinet to the installation
State the available grid input, maximum site power, indoor or outdoor installation, ambient conditions, slot quantity and fire-safety requirements. A reference 12-slot cabinet cannot be quoted as a complete system until the charger and battery interface are matched.
5. Freeze the operating and export scope
List the required apps, operator roles, payment method, remote monitoring, local hosting needs, language and API integrations. Required battery transport documents and destination-market compliance must be checked against the exact ordered model.
Product parameters, certifications and commercial terms must be reconfirmed against the exact model and shipment before order acceptance.
