Belarus Integrated Four‑Gun DC Fast Charging Case Study

Nancome multi‑gun solution: maximum throughput with minimum footprint

National EV Landscape Snapshot – Belarus

• Adoption is steadily rising with growing imports of electric taxis and private EVs; city centers and intercity corridors prioritize dependable DC nodes.
• Standards are predominantly CCS2 for passenger cars; multi-standard sites are appearing to serve mixed fleets and visiting vehicles.
• Operators focus on high uptime, cold‑weather reliability, and compact footprints near residential blocks and municipal facilities.

1) Project Overview

• Location: Urban public parking area, Belarus (integrated four‑gun cabinet, floor‑standing).
• Objective: Serve taxis, private cars, and municipal vehicles with concurrent fast charging in a constrained space.
• Configuration: One integrated cabinet with four independent DC guns; smart load balancing across outputs; multi‑standard options configurable (e.g., CCS2 with optional GB/T).
• Delivery: Nancome delivered feasibility, layout, civil & electrical works, commissioning, OCPP onboarding, and operator training under a one‑stop contract.

2) Why a Four‑Gun, Integrated Cabinet

• High integration & efficiency: Internal busbars and harnessing reduce connectors and failure points, simplifying installation and service.
• Independent operation: Each gun runs autonomously; the system follows vehicle BMS requests to allocate current, balancing speed and battery safety.
• Minimal footprint, maximum throughput: A single integrated DC fast charger cabinet replaces multiple pedestals—ideal for dense curbside lots.
• Thermal & acoustic optimization: Unified airflow paths and shared cooling keep acoustics low and module temperatures stable in long duty cycles.

3) System Design

Electrical & Power Management

• Modular rectifier packs enable N+1 reliability and quick hot‑swap maintenance.
• Smart load balancing charger logic assigns power per gun based on SOC, BMS max current, and site demand caps.
• Utility peak capping and overnight scheduling reduce demand charges for the public DC charging hub.

User Experience & Operations

• RFID/QR/Plug‑and‑Charge (where supported); large display guides new users and reduces attendant time.
• OCPP backend integrates with the operator’s app for pricing, receipts, real‑time monitoring, and remote diagnostics.
• Cable management and bollards protect pedestrians and vehicle movement around the cabinet.

4) Implementation Highlights

• Compact siting next to an apartment/office block with clear ground markings and a short cable reach to each bay.
• Four concurrent DC sessions during evening peaks keep taxis and private cars turning over quickly.
• Cold‑weather firmware and pre‑charge checks stabilize sessions in sub‑zero conditions common in Belarus.

5) Outcomes & ROI Snapshot*

*Indicative from comparable Nancome multi‑gun deployments; actuals depend on tariff and traffic patterns.
• Throughput: Up to 3.2–3.8 sessions per hour per cabinet at mixed SOC profiles during peaks.
• Utilization: Rapid ramp as drivers learn the site supports four parallel DC sessions.
• OPEX: Shared cooling and unified maintenance reduce service visits versus four separate pedestals.
• Revenue: Higher bay turnover and app‑based billing improve cash flow stability for the operator.

6) Build & Compliance

• Factory‑tested as a single integrated assembly; simplified permitting and fewer foundations.
• Surge protection, isolation monitoring, and DC contactor safety meet relevant IEC standards; cold‑weather kit optional.

7) Why Nancome

• Proven multi‑gun architecture with mass‑production experience and robust supply chain.
• One‑stop execution from design to O&M, with data analytics for tariff tuning and expansion planning.
• Serviceable modules, remote firmware, and localized UI ensure uptime through seasonal extremes.

Result: As Belarusian cities expand and mobility upgrades, Nancome’s four‑gun DC charging station turns limited curbsides into reliable public DC charging hubs. The multi‑gun DC fast charger unites high integration with independent outputs, delivering safe, fast, and profitable operations in a compact footprint.
