The MAHLE X20 Active Charger 4A represents a major advancement in charging technology for electric-assist bicycles. Designed for MAHLE X20 and X30 systems, this intelligent charger integrates real-time CAN BUS communication with the battery, enabling optimization of the charging process according to the actual cell state. Thanks to its powerful converter and adaptive current management from 0 to 4.5A, it ensures fast, efficient charging cycles that respect your battery's longevity.

Technical Highlights

• Intelligent CAN BUS communication: continuous dialogue with the battery to adjust charging intensity based on charge state, temperature, and cell health — ensures optimal charging and extends service life.
• Fast charging up to 4A: recharges the iX250 battery to 75% in under 2 hours and the iX350 to 82% in the same timeframe — ideal for cyclists in a hurry.
• Integrated micro-USB port: allows firmware updates of the complete e-bike system (GCU, motor, battery) directly from a PC — transforms your charger into a diagnostic and maintenance tool.
• Universal compatibility: wide input voltage range of 90 to 246 V AC (50-60 Hz), works anywhere in the world with the appropriate plugs (EU, US, UK, AUS versions available).
• Compact and lightweight design: only 690 g with dimensions of 187 x 90 x 44.4 mm — easy to transport and store thanks to the included wall mount.

Compatibility and Supported Systems

This active charger is designed to work with the entire MAHLE X Series ecosystem. It efficiently charges the internal batteries iX250 Wh (iX2+) and iX350 Wh (iX3+) as well as the Range Extender eX1 (e185 Wh). Thanks to CAN BUS communication, the charger automatically identifies the connected battery model and adapts charging parameters accordingly. Compatible with X20 and X30 systems, it integrates seamlessly with bikes equipped with next-generation MAHLE motors.

Safety and Durability

• Optimized thermal management: recommended operating temperature between -15°C and +35°C — the system stops charging if the battery or charger is too cold or too hot.
• IP20 protection: housing designed for indoor use, protected against solid objects larger than 12.5 mm.
• Intelligent adaptive charging: modulates charging power to preserve lithium-ion cell health and maximize battery pack longevity.
• Robust connector: reliable design for thousands of charge/discharge cycles.

Package Contents and Installation

The complete package includes the MAHLE X20 Active charger, a practical wall mount for fixed and organized storage, as well as a multilingual user manual. Installation is simple: attach the mount to the wall, plug the charger into mains power, and connect it to your battery via the dedicated charging port. The integrated LED indicator shows charging status in real time. For software updates, simply connect the charger to your PC via the micro-USB port and use the MAHLE SmartBike Lab application.
