Rapid Expansion of Vehicle‑to‑Grid (V2G) Services and Renewable Energy Integration
The global EV Bidirectional DC/DC Power Module market was valued at US$ 6.52 million in 2025 and is projected to reach US$ 40.22 million by 2032, expanding at a robust CAGR of 30.4%. This explosive growth is primarily driven by the accelerating rollout of V2G services, which transform electric vehicles into mobile energy storage assets that can feed excess electricity back to the grid during peak demand periods. In 2023, V2G-compatible charging stations increased by more than 45 % worldwide, and utilities in Europe and North America have already integrated over 5 GW of V2G‑enabled capacity. The adoption of renewable energy sources such as solar and wind has heightened the need for flexible, bidirectional power conversion to balance intermittency, and the DC/DC module is the critical enabler that facilitates seamless charging and discharging cycles while maintaining high efficiency (often exceeding 95 %). As grid operators seek to enhance stability and reduce reliance on fossil‑fuel peaker plants, the demand for reliable bidirectional modules that can handle rapid power direction changes is surging, thereby propelling market expansion.
Declining Battery Costs and Mass‑Market EV Adoption Fuel Demand for Bidirectional Modules
Battery pack prices have fallen by more than 60 % since 2015, reaching an average of US$ 130 kWh‑1 in 2024. This cost reduction has accelerated EV sales, with global registrations surpassing 14 million units in 2023—an increase of 38 % year‑over‑year. As EV fleets expand, manufacturers face the challenge of maximizing the utilization of on‑board energy. Bidirectional DC/DC modules enable not only fast DC charging (often 20 kW or higher) but also controlled discharge to external loads, unlocking new revenue streams for fleet operators through participation in demand‑response programs. The 20 kW and Below segment, which traditionally served low‑power auxiliary systems, is now being repurposed for grid‑interactive applications, projecting a compound annual growth rate of >35 % through 2032. This convergence of cheaper high‑energy‑density batteries and broader EV adoption creates a compelling economic incentive for OEMs and suppliers to integrate advanced bidirectional modules into vehicle architectures.
