Nextron Charging Connector Solutions for Micromobility
29 Nov 2021
One of the main challenges micromobility devices, such as e-bike, e-scooter and moped has been facing is the design of charging systems; the battery pack should be lightweight and waterproof with blind mating design to avoid damage caused by unproper insertion.
To solve the above mentioned problem and to ensure stable signal transmission on bumpy roads, Nextron has multiple ready charging solutions with unique floating designs: battery swapping solution with x, y floating range of 2mm, and larger charging module with x, y floating range upto10mm. Both designs features anti-vibration, waterproof, controllable inserting/extraction force and low contact resistance.
Regarding contact design, aside from the commonly seen crown spring, Nextron adopts blade type connectors ,which is not only a more cost-efficient option for devices such as e-bikes and mopeds, but also allows slide insertion that could cause damage to crown springs.
Blade type connectors could provide 30A current or more, with 10,000 insertion cycles. Contact resistance is lower than crown spring due to larger contact area.
