Charge Your E-Car Anytime, Anywhere!


Here is a portable electric-car charger which allows consumers to take their chargers anywhere so that drivers don’t have “range anxiety”. It also allows them to recharge the vehicle’s battery using almost any AC outlet. The charger uses innovative SiC Power MOSFETs from ST to offer exceptionally high energy-efficiency.

Using a built-in electronic transformer, the charger weighs 3kg and measures 45 x 10 x 10cm, making it ten times smaller and lighter than comparable products. Announced by Zaptec, it is claimed to be “the world’s smallest, smartest, and safest electric-car charging station.”

The e-charger delivers a high energy efficiency of 97% by virtue of the silicon-carbide (SiC) power electronics from STMicroelectronics. It uses 32 high-voltage SiC Power MOSFETs which are claimed to be exceptionally efficient and offer minimum losses. “When compared to silicon solutions, ST’s SiC power MOSFETs can sustain much higher voltages, currents, and temperatures, and their power-conversion circuits operate faster, enabling smaller, lighter designs, higher system efficiency, and reduced cooling requirements”, said ST in the Press release.

To ensure safety, the charger is water- and weather-proof, and galvanically insulated from mains power. It continuously monitors the grid it is connected to, dynamically adjusts the amount of power it delivers and shuts down immediately if it detects a fault, to protect the car.


Further, the charger offers GPRS connectivity and operates over an extended temperature range from -40°C to +55°C.

ZapCharger has completed successful field tests. Pilot production is starting now, while volume production is scheduled at the end of Q3 2016.
