EV charging solution overview

Vehicles that depend largely on fossil fuels for their energy present a major obstacle to the promotion of energy saving. Electric vehicles (EVs), on the other hand, have risen to prominence in recent years because of their potential to provide an effective solution to this problem.

Because they are fueled by electricity, EVs require the installation of chargers in suitable locations. If the majority of existing vehicles are to be replaced by EVs, a large amount of electric power will be required in the future. This means that charging systems also need to be managed efficiently. So that power can be supplied efficiently across the entire system, Hitachi plans to establish a network that can link these chargers together and exchange information between units installed in the home or at sites such as shopping centers or car parks.

This will also help in acquiring information from EVs in order to calculate and display the time required for charging, for example. It is also possible to link the system to power plants so that operation can coordinate with non-EV power requirements.

Use of a charger network will also allow a more extensive range of user services and enhancements to vehicle use, such as issuing coupons or distributing advertisements.
