Custom Drone Charger FAQ

Questions About Custom Drone Battery Charger Projects

These are some of the most common questions we receive when evaluating custom drone and UAV battery charger projects.

Can EV-PEAK develop a charger for our existing drone battery and BMS?

Yes. If your battery and BMS are already defined, EV-PEAK can evaluate the battery specification, charging requirements, existing BMS interface, connector, mechanical constraints and operating environment to develop a charger around the existing battery platform.

What information do you need to evaluate a custom charger project?

Typical starting information includes battery chemistry, cell configuration, nominal and maximum charging voltage, maximum charging current, capacity, BMS specification, communication interface if applicable, connector and pinout, target charging time, required number of charging channels, mechanical requirements and expected project quantity.

Can the charger integrate with our existing BMS communication interface?

Where the battery platform already has a defined BMS interface or charging protocol, EV-PEAK can evaluate the available interface specification and develop the charger-side integration required for charging control, battery status and other supported data functions.

Can you customize the connector, battery dock and enclosure?

Yes. Depending on the project, customization can include output connectors, cable assemblies, battery slots, dedicated charging docks, enclosure dimensions, installation interfaces and other mechanical requirements around the target battery.

Can EV-PEAK develop multi-bay chargers for drone fleet operations?

Yes. EV-PEAK has historical experience with dual-channel, three-bay and multi-channel charging systems. Channel quantity, simultaneous or sequential charging, charging power and battery docking can be developed around the required battery throughput and operating workflow.

Can you develop vehicle-powered or field charging solutions?

Yes. EV-PEAK has developed historical charger platforms using vehicle DC input as well as AC-powered configurations. Input architecture can be selected or developed according to how and where the UAV system will be operated.

Can EV-PEAK support production after prototype validation?

Yes. Qualified projects can progress from engineering review and prototype development through battery validation, pilot production, customer approval and commercial production supply.

Are the historical DJI, YUNEEC and PARROT chargers shown on this page official products from those brands?

No. EV-PEAK historically had official-supplier relationships with DJI, YUNEEC and PARROT, but the compatible chargers shown in the engineering cases on this page were independently developed EV-PEAK third-party products. They were not the products supplied under those official supplier relationships.
