High Frequency Battery Chargers AECF-3

The high-frequency battery chargers Amperis AECF-3 are designed to charge batteries in the range of 12-160V. A variety of charging algorithms are available, making the AECF-3 chargers suitable to recharge batteries of any type, in motive and stand-by applications, including Lithium-ion packs of the last generation.

These chargers can operate in fully automatic, standalone mode, or they can be interfaced with with BMS modules of different types, including the Amperis BKS System, through PWM or CANBUS interface.

Thanks to their flexibility, the robust and compact design they are universally applicable. The installation on board of EVs is simplified by the compact size and the regular shape.

The particular configuration of the ventilation system allows the installation of the unit in any position and orientation, without limitations in the air flow. The power electronics operate at a frequency of 70kHz, and are based on semiconductors of the last generation.

An active electronic circuit protects the charger completely in case of: reverse polarity of the battery, wrong voltage of the battery, overload, overtemperature and short-circuit of the output.
