- FAQ
Can the charging modules be upgraded to higher power ratings in the future?
In some cases, depending on the module's design and hardware architecture, it may be possible to upgrade to a higher power rating by charging high power capacity charging modules in same dimension.
How does the charging module handle frequency fluctuations within the specified range?
The module is designed with internal circuitry that can adapt to frequency fluctuations within the 50/60Hz +/- 5Hz range. It ensures stable operation and charging performance, adjusting its internal control systems to maintain proper power conversion and charging parameters.
What is the Total Harmonic Distortion of the input current (THDi) of the charging modules?
The THDi is ＜3% under nominal power. A low THDi is important as it reduces the harmonic pollution in the power grid, minimizing interference with other electrical equipment connected to the same grid.
How does the charging modules achieve such a high power factor and low THDi?
The use of advanced power electronic control technology, such as active power factor correction (APFC) circuits, helps the module achieve a high power factor and low THDi. These circuits actively adjust the input current waveform to be in-phase with the input voltage, reducing harmonic components.
How is the zero-standby-power-consumption feature achieved?
Through external control, some of the charging modules can be completely powered off in standby mode. This may involve cutoff internal power circuits, where no power is drawn from the AC input.
What are the benefits of zero standby power consumption?
It significantly reduces energy waste, especially in charging stations with multiple modules. Over time, this can lead to substantial cost savings on electricity bills and also contributes to environmental sustainability.
Why is the nominal power specified within a certain voltage range?
The charging efficiency and performance of the module are optimized within the 300-1000Vdc range. Under this range, the module may operate at a reduced power level or with lower efficiency to ensure safe and reliable charging.
How does the module maintain high efficiency during operation?
The module uses advanced power-conversion components and optimized control algorithms. The design of the power-electronic control topology also plays a crucial role in minimizing power losses during conversion, ensuring high-efficiency operation over a wide range of input and output conditions.
What communication interface does the charging module use?
The charging module uses the CAN (Controller Area Network) communication interface, bitrate 125kbps. CAN is a widely used, reliable, and efficient communication protocol in the automotive and industrial sectors.
How many charging modules can be installed in parallel?
A maximum of 60 modules can be installed in parallel. Parallel installation allows for higher total power output in charging stations, meeting the demand for charging multiple vehicles simultaneously or charging high-capacity batteries more quickly.
