Inductive charging is becoming an increasingly integral part of the lithium battery ecosystem. The rise of artificial intelligence is paving the way for autonomous systems, where drones can recharge themselves without human intervention. We are entering a new era of autonomy, and inductive recharging is an essential pillar of this.

For professionals, power calculation is at the heart of every project. How do you choose the right induction charging model for your drones? It all depends on the usage scenario.

In this case, the drone is shut down for recharging. The aim is to find out the battery capacity to determine the charging power required.

• Rule of thumb: a full charge should take 4 hours.
• Example: For a 2000 Wh battery, you’ll need a 500 W induction charger.

This solution is ideal for drones that land on a ground charging station after their mission.

The drone may need to be recharged while remaining active. For example, the drone may remain 10 cm above the charging plate and continue to operate.

• Basic rule: the charger’s power must compensate for the drone’s power consumption and recharge the battery.
• Example: If the drone consumes 200 W during a 4-hour charge, it will have consumed 800 Wh. The induction charger will therefore need to supply the 500 W from the previous example, plus the 200 W consumption, i.e. a capacity of at least 700 W.

This solution is ideal for missions where the drone needs to maintain a constant power supply, even during recharging.

Induction charging is compatible with 110V/220V AC or 12V to 48V DC power supplies. Interested in this solution for your drone batteries? Contact us to find out more.
