Newest Small 6mA DC RCD for Portable EV Charger

Portable electric car chargers are a relatively new arrival on the EV scene and they could make all the difference. For many new adopters of electric motoring, range anxiety is often found lurking at the back of the driver’s mind. A portable charger will suit the majority of vehicles that utilise Type 1 or Type 2 charging cables. It’s a great idea, so what’s to stop a driver carrying one in the boot? Well, some models can be very expensive and any will add weight to a car; never a good thing. People who drive very long distances as part of their work may find it useful to carry one as a stop-gap, but perhaps the idea is a bit over the top for most domestic motoring. If range is of concern day to day then it is best to ensure a regular regime is adopted to ensure the vehicle is at maximum charge whenever possible. That said, a smaller lighter unit might provide some peace of mind for family motoring, say. Home charging stations however are a must-have and, say, an app that identifies where public charging points are available in any given area. By keeping an eye on consumption just as a driver would a petrol gauge, there’s no reason to worry about range. The good news is that motoring and breakdown organisations are beginning to equip their service vehicles with a portable charger that connects to the popular EV connectors. That way, in extremis, a driver knows that his provider can come out to deliver a power boost at the roadside much as they would with a jerry can for a petrol or diesel car, to get the stranded motorist on their way again. It seems likely that as electric car use grows so garages and dealerships will routinely add portable electric chargers to their service vehicles. Similarly hire car providers could have them available for customers in an emergency and business users could make them a vital part of on-board fleet equipment to ensure their vehicles can get to a regular recharging point or back to base.

MD0630T01A-2 is a new small leakage current sensor for portable charger(mobile charger), which can also be called residual current sensor, residual current monitor (RCM), residual current device (RCD), differential current sensor, leakage current protector, fault current sensor etc. The internal parts of the portable charger should be as small as possible, our new leakage detector is small and lightweight, which just meets this requirement. This residual current monitor will detect DC and AC residual currents in 50Hz/60Hz AC installations according to IEC62955. It's primarily intended for use in Electric Vehicle charging stations to disconnect the supply to the Electric Vehicle under a DC residual fault current condition. It will protect against DC (6mA) and AC (30mA) residual currents, and will signal to the Smart EVSE if a fault occurs.

In electric vehicle charging if the DC fault current is greater than 6mA, it could change the characteristics of a Type A RCD due to its core saturation, resulting in the type A failing to trip and a lack of detection of the DC fault. In this instance, the risk of electric shock is increased, and safety is compromised. IVY has launched a new 6mA DC sensor that is designed to detect a DC earth fault, which is more cost-effective than using a Type B RCCB. In the event of a dangerous electrical fault, the sensor will output an alarm signal (by setting the leakage alarm value). This new 6mA DC sensor enables compliance with the updated IEC62955:2018 and reduces the cost of developing electric vehicle charging solutions.

Charging piles are gradually becoming popular in society and families. For equipment safety, personal safety, and power safety, whether they are indoors or exposed outdoors, their safety protection must be indispensable. 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.
