Innovating the Future of Lithium Energy Storage

Engineering Your Energy Future

Chalong Fly supports OEM/ODM battery development from cell and BMS selection through mechanical integration, interface definition, prototype validation and production transfer.

1. Smart BMS Development

BMS configuration and integration can be developed around agreed project requirements, including communication, protection logic, parameter setup and interface validation.

  • Hardware & Software integration
  • Communication interfaces: CANbus, RS485, RS232, Bluetooth or UART, depending on project architecture

2. Structural & Thermal Design

Mechanical design can include enclosure layout, mounting, cable routing, service access, thermal considerations and project-specific sealing or ingress-protection targets where required.

  • Vibration and shock considerations based on application requirements
  • Thermal-management evaluation for the expected operating conditions
  • Project-specific sealing or ingress-protection targets where required

3. Testing & Validation

Testing and validation are planned according to the application, agreed scope and project validation requirements.

  • Safety and Electrical Testing: Electrical and functional checks, BMS protection and over-charge/over-discharge response, with additional checks according to the agreed validation scope.
  • Environmental Testing: Temperature-performance and thermal-cycle evaluation according to the application and validation plan.
  • Mechanical and Interface Testing: Mechanical inspection, vibration/shock assessment and communication verification where applicable.

R&D and Customization FAQ

Can you customize the BMS communication protocol to match our specific inverter or vehicle?

Chalong Fly can support BMS communication integration for OEM/ODM projects, including interfaces such as CANbus, RS485, RS232 or UART where applicable. The final interface, message mapping and parameter set are defined according to the target inverter, controller or equipment and verified during project validation.

How long does it take to get a custom battery prototype?

Prototype timing depends on the electrical architecture, enclosure, BMS and communication requirements, component availability and validation scope. After requirements are confirmed, the project team can provide a development schedule for the engineering, prototype and validation stages.

What safety tests are performed on the battery packs before shipment?

The validation plan is defined according to the application and agreed project scope. It can include electrical and functional checks, BMS protection verification, insulation checks, temperature evaluation, vibration or shock assessment, communication testing and other applicable validation items. See our Quality Control page for the quality and testing process.

What type of cells do you use for your custom battery packs?

Cell chemistry, format and grade are selected according to project voltage, energy, current, size, temperature, cycle-life and compliance requirements. LiFePO4 is commonly used for many industrial and energy-storage projects, while the final cell selection is confirmed during engineering evaluation.

Do you support low-volume customization for new R&D projects?

Prototype and pilot-build quantities can be discussed according to project scope, component availability and manufacturing requirements. The purpose of the early build stage is to validate the design before production scale-up.
