EVSE Solution-MD Series Residual Current Monitoring Device

After a long “home order” and lockdown period, the European auto market finally restarted with difficulty. In the face of the auto industry that has been hit hard by the epidemic, European governments have recently introduced stimulus policies, and these policies, without exception, focus on supporting the development of the electric vehicle industry. In addition to the "overweight" of subsidies for electric vehicle purchases, European governments have also actively allocated funds to vigorously promote the construction of electric vehicle charging infrastructure.

On the one hand, the sales of electric vehicles in Europe continue to grow, and the current public charging piles may not be able to meet the needs of future users; on the other hand, consumers’ "mileage anxiety" about electric vehicles is also one of the main reasons that affect car purchases. Therefore, speeding up the construction of charging piles has become a top priority. The European Union and many European countries have also included accelerating the construction of public charging piles as one of the priorities of this round of stimulus policies for the car market. In fact, in recent years, in order to promote electric vehicles, many multinational car companies have also deployed charging infrastructure construction. At the same time, in the face of the wave of electrification, many oil giants have coincidentally aimed at the vast charging pile market.

The most important safety issue of electric vehicle charging piles is whether the electric vehicle charging pile can avoid accidents caused by plugging and unplugging the charging gun at will during the charging process, whether it can automatically cut off the power after the charging is completed, and whether it can be insulated in rainy days. Avoid electric shock, which is a question for many electric vehicle users. Although circuit protection is only a part of the design of industrial products, it is a very important design, because protection devices or protection products are usually at the entrance, such as the input port of the power supply. Once the protection device has a problem, the entire system will not be able to be timely use. For this reason, IVY has developed a special residual current protection device for charging pile equipment-MD series leakage current sensor, a special residual current monitoring device that can be directly installed on the control panel of charging piles and other various electrical equipment. For charging piles and other electrical equipment and subsequent facilities in the AC and AC residual current containing DC components to monitor and supplementary protection against personal electric shock.

MD0630T01A is a high-sensitivity AC and DC leakage current sensor used in electric vehicle charging stations. It can also be called a residual current sensor, a residual current monitor (RCM), a residual current device (RCD), a differential current sensor, and a leakage detection sensor. , Fault current sensor, etc. This residual current monitor will detect the DC and AC residual current in the 50Hz/60Hz AC device according to IEC62955. It is mainly used in electric vehicle charging stations to disconnect the power supply of electric vehicles under DC residual fault current conditions. It will prevent DC (6mA) and AC (30mA) residual currents, and send a signal to the smart EVSE in the event of a failure.

MD series residual current sensor (RCD/RCM) is an ideal protection device for detecting and protecting different leakage current/residual current/fault current. When someone gets an electric shock or the leakage current exceeds the specified value, RCD can quickly output an alarm signal to protect the safety of people and electrical equipment. As a B-type RCD, MD series leakage sensors are widely used in many industries such as electric vehicle charging, photovoltaic systems (solar panels), industrial equipment, medical equipment, new energy, DC panels, fire-fighting power distribution cabinets, and the Internet of Things. Any installation where there is a risk of DC current flowing. This technology brings us the closest to full protection of all known residual fault currents.

At present, it is common in the market to monitor or output an alarm signal for a single AC or DC leakage current at the same time, and our leakage current sensor can set the leakage current in the application of DC and AC, and generate an alarm signal when the set current is reached. , And can output switch control signals. At the same time, it has a digital output function, which can read the current value of DC and AC.

Charging power sources or charging piles have gradually become popular in society and families. Whether they are indoors or exposed outdoors, their safety protection must be indispensable. For equipment safety, personal safety, and electrical safety, our MD series leakage sensors are the best choice for charging pile accessories. With the vigorous development of charging piles in various European countries, our MD series leakage sensors are very popular in Europe and have won good praise.
