Technical FAQs 4

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.

Does bidirectional charging reduce NPV?

Owing to higher initial costs, bidirectional charging experiences a temporary decline in NPV because of possible costs associated with maintenance, infrastructure, or grid integration. However, bidirectional charging could still be beneficial for energy optimization and grid support, despite its lower NPV.

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.

Can bi-directional charging be a Mainstream Energy Solution?

Sigenergy is proud to be among the first to successfully implement bi-directional charging in a commercial setting. In partnership with NIO, a leading EV manufacturer in China, Sigenergy has demonstrated the viability of bi-directional charging as a mainstream energy solution.
