Wise-integration and Savoy launch first GaN charger embedded with e-bike battery

Wise-integration of Meylan, France — which was founded in 2020 and designs and develops gallium nitride (GaN) integrated circuits and digital-control technologies for power supplies — and France-based tier-1 automotive supplier Savoy Group have announced a new GaN charger for e-bikes embedded with the battery of the new Cocotte electric bike, designed and manufactured by KILOW (a rebranded light e-mobility division of Savoy Group).

Launched at the EUROBIKE 2023 event in Frankfurt Messe, Germany (21-25 June), the urbanized e-bike and on-board charger together are said to free riders of two common pain-points that they face on the streets: running out of power and packing the added weight of portable chargers.

What is claimed to be the world’s first GaN on-board charger and Wise-integration’s GaN devices for e-bikes are a highly integrated solution assembled by Savoy Group.

“Our charger is embedded in the battery itself, making it the lightest, most compact and convenient charger on the market,” claims Wise-integration’s CEO Thierry Bouchet. “This technology enables e-bike users to easily charge their bikes on the go, wherever they are.”

“Anything we take away, be it weight, electronics or gadgets, actually gives the user something more in terms of maintenance, ease of use or peace of mind,” says Arthur Allamand, marketing director for KILOW.

Wise-integration aims to extend its GaN products and solution for power supply and e-bike manufacturers across the European market. Due to the combination of the WiseWare AC-DC digital controller and WiseGan GaN device, Wise-integration says it is able to improve power density to provide more power for embedded fast-charging capabilities.
