IVY RCD Modules Provide Residual Current Protection for EV Chargers

With the rapid growth of the electric vehicle market, the demand for electric vehicle chargers has increased dramatically in recent years. According to the charging current type, electric vehicle chargers are divided into AC chargers and DC chargers. AC chargers are compact and easy to install and are usually best suited for residential units, workplaces and communities where they are installed in public parking lots/garages. Due to the large market demand, AC chargers are currently the mainstream in the market.

Generally speaking, the charging current power of electric vehicles ranges from several kilowatts to tens of kilowatts. Therefore, safety protection is crucial for electric vehicle charging. Many countries have proposed corresponding safety regulations, especially emphasizing the importance of leakage protection for electric vehicle chargers.

In electric vehicle charging, there are a large number of AC-DC conversion (rectifier/inverter) circuits. Therefore, if a leakage fault occurs, not only AC and pulsating DC residual currents will be generated, but also DC residual currents and smooth DC residual currents generated by two-phase/three-phase rectification and filtering will be generated.Therefore, if a leakage fault occurs, not only AC and pulsating DC residual currents will be generated, but also DC residual currents and smooth DC residual currents generated by two-phase/three-phase rectification and filtering will be generated. Therefore, leakage protection solutions need to be able to detect both AC and DC residual currents.

IVY has recently developed a series of RCD protection modules with leakage protection solutions suitable for EU standard Mode 2 and Mode 3 EV chargers.

Compared with traditional Type A leakage protection products, IVY EV-RCD modules have the following advantages:

Excellent accuracy: detects 3-6mA DC/15-30mA AC differential current and sends a response signal according to safety requirements.

Can detect multiple current types: realize B-type leakage detection.

IVY Metering'series of residual current sensors is a reliable solution for the EV charger. They come in multiple packages for a wide range of applications and can detect and measure residual currents, helping prevent electrical accidents and ensuring the safety of personnel and equipment. Whether you want to monitor residual currents in industrial settings, commercial buildings, or residential properties, we have a solution to meet your needs.
