One of the obstacles to the spread of electric vehicles is the long charging time.To shorten this, CHAdeMO had previously planned an ultra-fast charger with a maximum output of 350kW.However, in order to install this, a power receiving facility with a high voltage of 350 kW or more is generally required, and the installation requires a large space and a high cost.

Electricity storage type ultra-fast charger (utility model 3219348) is equipped with a storage battery of 60kWh or more and a quick charger with an output of 350kW or more.With a low voltage contract, it can be installed even in a small place.The stored electricity can be charged to an electric vehicle in a few minutes.

When charging the storage battery of the storage type ultra-fast charger, the battery is charged with the highest amount of power within the range so as not to exceed the power contracted with the power network.

Installing these energy-storage ultra-fast chargers in places such as convenience stores, supermarkets, and company parking lots will increase the number of places where electric vehicles can be charged, helping to promote the spread of electric vehicles.In addition to charging electric vehicles, the energy-storage ultra-fast chargers can also be used as a backup power source for the business in which they are installed in the event of a power outage in the power network.
