The charger module is the inner power module for DC charging stations (piles), and convert AC energy into DC in order to charge vehicles. The charger module takes a 3-phase current input and then outputs the DC voltage as 200VDC-500VDC/300VDC-750VDC/150VDC-1000VDC, with an adjustable DC output to meet a variety of battery pack requirements.

The charger module is equipped with a POST (power on self-test) function, AC input over/under voltage protection, output over voltage protection, over-temperature protection and other features. Users can connect multiple charger modules in a parallel manner to one power supply cabinet, and we guarantee that our connect multiple EV chargers are highly reliable, applicable, efficient, and require very little maintenance.

Applications

The charger modules can be used on DC fast charging stations for EVs and E-buses.
Note: The charger module does not apply to on-board chargers (inside cars) .

Advantages

• System space is saved due to a high power density, and each module has a power of 30kW, 40kW or 60kW.
• Wide input voltage: 260V-530V, designed with input surge protection.
• The charger module uses DSP (digital signal processing) control technology, and is fully numerically controlled from input to output;
• Uses interlaced series resonance soft switch technology to reduce the tolerance of power devices.
• Input THDI < 3%, input power factor reaches 0.99 and overall efficiency reaches 97% and above
• Wide output voltage range: 200VDC-500VDC, 300VDC-750VDC, 150VDC-1000VDC (adjustable), is able to meet various voltage demands of different charging requirements
• Low DC ripple causes minimum effects on the battery lifespan
• Standard configuration of CAN/RS485 communication interface, allows easy data transferring with external devices
• The charger module is equipped with input overvoltage protection, undervoltage alarming, output overcurrent and short circuit protection functions.
• The charger modules can be connected in a parallel system, allowing for a hot swapping and easier maintenance. This also ensures the system applicability and reliability.
• The charger module is designed with full SiC (silicon carbide) components to ensure high-speed switching, low on-state resistance, and high voltage endurance.
• With Class B EMC standards, providing superior interference suppression and broad residential environment application suitability.
