As electric vehicle adoption surges, the role of the EV battery is undergoing a paradigm shift. No longer just a sink for electrical energy, the modern EV is an active Distributed Energy Resource (DER). Bidirectional EV chargers sit at the epicenter of this shift, facilitating two-way power transmission: charging the vehicle (Grid-to-Vehicle, G2V) and exporting energy back to the home (Vehicle-to-Home, V2H) or the grid (Vehicle-to-Grid, V2G).
Enables EV batteries to act as residential back-up power supply during blackouts. By linking the home's distribution panel to our smart bidirectional charger, users can prioritize solar self-consumption and lower peak utility fees.
Enables utility-scale grid balancing by aggregating parked EVs to feed power back into regional grids. This provides peak shaving and frequency regulation services, turning private fleets into decentralized power plants.
Our systems incorporate the latest communications frameworks, supporting secure Plug & Charge functionality and encrypted vehicle-to-charger-to-grid handshakes for complete grid stability compliance.
The transition from unidirectional (G2V) charging to highly networked, bidirectional systems is occurring rapidly. Walnut Charger is actively leading this engineering transformation. Below is our strategic focus roadmap aimed at meeting future infrastructure requirements:
Transitioning from traditional IGBTs to Wide Bandgap Silicon Carbide (SiC) semiconductor technologies. SiC lowers switching losses, reduces component size by 35%, and increases round-trip conversion efficiency to over 97% during vehicle discharge phases.
Integrating localized solar PV arrays, stationary BESS (Battery Energy Storage Systems), and bidirectional EV chargers under a centralized energy broker. This utilizes AI prediction algorithms to dynamic shift charging based on solar peaks.
Implementing native ISO 15118-20 (Bidirectional Power Transfer) profiles, enabling seamless AC/DC vehicle-to-grid communications across all international EV manufacturers (CCS, NACS, and GBT interfaces).
Operating a world-class manufacturing complex in Foshan, China, Walnut Charger integrates advanced robotics, digital twins, and Lean assembly systems to address the primary concern of global procurement managers: Supply Chain Risk.
Our facility houses high-speed surface-mount technology (SMT) lines that construct the critical logic boards and control cards in-house. To ensure defect-free shipments, every power module undergoes Automated Testing Equipment (ATE) validation, subjecting chargers to real-world grid anomalies and high-temperature environmental simulation chambers before packaging.
By positioning our manufacturing assets in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA), we maintain direct partnerships with key component foundries (semiconductors, copper relays, magnetic components). This integration minimizes lead times and shields our supply chains from global material shortages.
Integrating EV charging infrastructure requires specialized configurations depending on the end-use ecosystem.
Dynamic Load Balancing (DLB) ensures that multi-family apartment buildings can deploy multiple EV charging units without exceeding the facility’s mains rating, optimizing smart power allocation.
Our solutions feature dual-port outputs and support Ethernet/4G connectivity, allowing logistics operators to track fleet state-of-charge (SoC) and plan charging cycles to match off-peak hours.
Leveraging OCPP 1.6J/2.0.1, operators can connect charging infrastructure directly to external billing software, monitor system health remotely, and perform over-the-air (OTA) diagnostic updates.
Walnut Charger simplifies global system deployments by engineering our products for direct compliance with regional safety codes, grid connection standards, and wireless protocols.
