Bidirectional Charging of Jordanian Photovoltaic Energy Storage Containers for Ships

Are bidirectional EVS a viable option in Jordan?

While bidirectional EV setups enhance self-consumption and reduce dependence on the external grid, they face financial challenges, including higher initial costs and a lower net present value (NPV) due to maintenance expenses. In Jordan the time-of-use (TOU) pricing system has applied for EVs charging.

How does a bidirectional charging system work?

For the bidirectional charging system depicted in Fig. 4 b, the PV system charges the EV battery via unidirectional charging but introduces a discharging functionality to manage the energy distribution dynamically. This prevents the SOC from remaining fully discharged at 100% SOC, as energy is discharged when needed.

Are unidirectional and bidirectional electric vehicle chargers profitable in Amman?

The results of the profitability study comparing unidirectional and bidirectional electric vehicle (EV) chargers in Amman are presented in Table 5. In general, the investment costs of the unidirectional EV system are lower than the initial investment costs of the bidirectional system (7,480 USD vs. 8,880 USD).

What is EV bidirectional charging?

Unlike unidirectional charging, bidirectional charging distributes excess PV power more effectively, maximizing the benefits of solar generation and supporting energy demand more efficiently. The use of EV bidirectional technology reduces total electricity consumption.
