The dynamic allocation unit (DAU) flexible charger is designed based on power distribution units. Any charging gun can call any charging module. The product features flexible system configuration and power distribution. It is especially suitable for scenes with diversified charging needs, like airports and bus depots, etc.

Multiple charging terminals
Configured with multiple charging terminals, which can provide DC fast charging for multiple vehicles at the same time

Intelligent power distribution
Dynamic switching of charging modules and any charging gun connected to any module is enabled, to meet the charging needs of different powers and maximize the efficiency of the charger

Optional charging modes
Optional charging modes for users, such as average distribution and priority allocation of charging modules, etc.

Modular design
Pluggable power distribution module for fast operation, maintenance, inspection and repair

Higher reliability
Multiple protections like auto power off on abnormal charging, overcharge protection, failure isolation, etc. The failure of any single terminal does not affect the normal operation of the others

Smart management
Supporting charging cloud platform management, enabling intelligent monitoring, remote maintenance, and online upgrade via the back office
