3kW 12-48V CANbus Hybrid Power Charger

  • ;Charges a low side (12V) battery from either 24V or 48V at 3000W at over 95% efficiency.
  • Charges or assists the high voltage (24V or 48V) battery at 3000W at over 95% efficiency.
  • Enters “Pre-charge” mode when the 48V battery has additional external charging (like solar controller or inverter/charger).
  • Ruggedized design with 8mm thick aluminum baseplate with 5mm powder coated steel cover.
  • Designed to meet MIL-STD-810G for harsh shock and vibration environment
  • Compact size of only 220 x 150 x 25 mm. 
  • Light-weight at only 1.3kgs with a low-profile design
  • Efficiency up to 97%, one of the highest power densities available.
  • Operational temperature range is -40˚C to 100˚C. 
  • Safety disconnect switch for charging from or to the 12V battery.
  • reverse voltage protection, short circuit protection, as well as low standby current for the low side.

Two-Way Operation at 3,000W

Constant Current Mode and Direction Selection

The charger operates as an ideal current source with variable direction when the output voltage is lower than the voltage specified by the CAN interface. This configuration allows energy transfer between the 12v and 48V. The 12V current can be programmed in the range of 1A-250A. The charger has an internal soft start to reduce inductive voltage drop in the power cables during both turn-on and turn-off. The charger will not operate if the current is set to zero or it is outside the limits. Charging current level can be changed on the fly.

  • The direction of the current can be changed dynamically during operation. In that case, the charger will shut down and change the mode of operation through the internal soft start thus eliminating surge current during the direction change.

 

Safiery use an embedded CANbus controller with interface for complete control of the charger, as well as monitoring the current and the internal temperature.

The following functions are fully controlled via CAN interface:

  • ON/OFF
  • Current and voltage set points
  • Current direction
  • Protection threshold: Under-voltage, Over-voltage and Over-temperature
  • In addition, the 12-48V Hybrid CANbus Charger provides low side current monitoring and internal PCB temperature monitoring.
