Battery Charger

The PowerCharger family is part of the SmartBMS™ battery systems, especially for vehicle and subsea batteries. The PowerChargers™ are integrated with the Battery BMS in order to achieve multiple safety levels and fast charging. In addition to the data interface, a “safety loop” is available independently. Temperatures, voltages, currents and other parameters are read directly from the battery. Both the BMS and the PowerCharger™ can intervene in the charging process for safety reasons.

A PowerCharger™ can charge one battery, multiple battery channels or multiple battery modules. For this it has one or more controllable high-power power-supplies. In addition to the usual CC/CV characteristics, SubCtech has implemented a fast and smart algorithm that includes faster balancing.

As usual operation with SubCtech PowerCharger is simple: with the press of a button charging, discharging for storage or transport, and diagnostics (e.g. capacity measurement) are carried out.

In addition, an optional power supply can operate the vehicle independently while charging.

A 7″ color touchscreen provides summarized overview-information about the system. In addition, you can view all parameters down to the cell level via graphic submenus.

For service purposes, the battery BMS firmware or the battery configuration can be updated via the USB port. This means that adjustments can also be made “on the fly”. Log files can also be downloaded via the USB port

 

Options

    • Special double charger for redundant battery designs
    • Standby and emergency charge
    • Discharge unit for diagnostic and automatic storage/transport discharge
    • Additional power supplies to operate your vehicle during charging
    • Data interface to host systems (NMEA-0183 or MODBUS RTU)

     

Benefits

    • Extremely robust: waterproof for offshore and on-board conditions
    • Safety: automatic control of all charging states
    • Reliability: simple design eliminates weak control elements
    • Minimum costs: long lifetime, short charging cycles
    • Simple handling: Plug’n’play charger, charge on board without opening the housing, charge under water. No overcharging: the chargers can be left permanently attached to the batteries
    • Special procedure revives even deeply discharged batteries
    • Maintenance free: little time and costs
    • Wide range of voltages and capacities available
