Japan's Nichicon says it has developed "the world's smallest and lightest quick chargers" with two units that take 35 to 60 minutes to charge.
The Kyoto-based capacitor maker says the NQC-A202 charger is about 5 feet tall and 13 inches wide, weighing 330 pounds.
It has an output capacity of 20 kilowatts. The NQC-A302 unit has a 30kW capacity but weighs 375 pounds. The output voltage is 50 to 500 volts DC.
The company says the chargers are half the weight and size of existing models but still meet standards set by CHAdeMo, a rapid-charge association led by Tokyo Electric Power Company and Japanese automakers.
The chargers will be aimed at car dealerships and other customers. They will hit the market in October and will sell for 1.89 million to 2.1 million yen ($24,500 to 27,220), the Nikkei newspaper reported.
As of last month, there were nearly 800 CHAdeMo rapid-charge stations on the road, with the vast majority in Japan.
