The Sennan Electric 240kW charging station sits at the top of the standard DC product line, offering the fastest charging speeds available before entering the supercharging category (250kW+ air-cooled and 600kW liquid-cooled systems).
The 60kW DC Charging Station: Entry-Level Commercial
The 60kW model is the workhorse of urban commercial charging. It provides sufficient power for most passenger EVs — delivering roughly 60 kilometers of range per 10 minutes of charging — while keeping equipment and installation costs manageable. For site operators building their first charging location, the 60kW station offers an accessible entry point.
Available in two color options — Dark Gray and New Blue — the 60kW model features an integrated design with a built-in power module, charging controller, and user interface. The unit supports standard CCS2 and CHAdeMO connectors, with optional dual-gun configurations for simultaneous charging of two vehicles at reduced power per gun.
Key Sennan Electric DC charger specifications for the 60kW model include:
- Input voltage: Three-phase 380V ±15%
- Output voltage range: 200–1000V DC
- Maximum output current: 200A (single gun)
- Efficiency: ≥95%
- Protection rating: IP54
- Operating temperature: -25°C to +55°C
The 60kW station is ideal for retail parking lots, hotel parking, municipal charging points, and small fleet depots where vehicles typically park for 1–2 hours.
The 80kW DC Fast Charging Station: Balanced Performance
Stepping up to 80kW, charging times decrease by approximately 20–25% compared to the 60kW model. This makes the 80kW unit suitable for locations where faster turnaround translates directly to higher revenue per charging bay. Shopping mall parking structures, highway-adjacent rest stops, and taxi/ride-hailing charging hubs benefit from the improved throughput.
The 80kW model shares the same physical enclosure and architecture as the 60kW, differing primarily in the power module configuration. This standardization across Sennan DC fast charging station models simplifies maintenance training and spare parts management for operators running multiple station types.
The 120kW DC Charging Station: The Sweet Spot
The 120kW model is the most popular configuration in the company's DC product line, representing the optimal balance between charging speed, equipment cost, and grid connection requirements. At 120kW, most passenger EVs can charge from 10% to 80% in 20–35 minutes — a timeframe that aligns with typical consumer behavior at convenience stores, restaurants, and retail centers.
The 120kW station typically employs a dual-gun configuration, allowing two vehicles to charge simultaneously. Power allocation is dynamic: when both guns are active, each receives up to 60kW; when only one vehicle is connected, the full 120kW is delivered to that vehicle. This flexibility maximizes utilization and revenue.
Key specifications for the 120kW model:
- Input voltage: Three-phase 380V ±15%
- Output voltage range: 200–1000V DC
- Maximum output current: 200A per gun (single gun mode), 200A total (dual gun mode)
- Number of charging guns: 2 (CCS2 + CHAdeMO, or dual CCS2)
- Efficiency: ≥95%
- Power factor: ≥0.99
The 160kW and 180kW DC Charging Stations: Highway Performance
As charging networks expand to highway corridors, higher power ratings become essential. The 160kW and 180kW models are designed for highway rest stops and intercity charging plazas where drivers expect to complete a charging session within a typical rest break of 15–30 minutes.
The 160kW and 180kW models are available in both Dark Gray and New Blue color options, with the same dual-gun configuration and dynamic power allocation as the 120kW model. The Sennan Electric DC charger specifications for these models include:
- Output voltage range: 200–1000V DC
- Maximum output current: 250A (single gun)
- Efficiency: ≥95%
- Standby power consumption: ≤15W
- Communication interfaces: Ethernet, 4G, RS485
- Payment integration: RFID card reader, QR code payment
- Safety certifications: CCC, CE
The 240kW DC Charging Station: Top-Tier Standard Charging
The Sennan Electric 240kW charging station represents the highest power tier in the company's standard DC product line before the transition to dedicated supercharging architectures. At 240kW, a typical 75kWh passenger EV battery can be charged from 10% to 80% in approximately 10–15 minutes, approaching the experience of traditional refueling.
This model is designed for high-traffic highway charging plazas, commercial fleet depots with 24-hour operations, and premium urban charging hubs targeting drivers who prioritize speed. The 240kW station features a split-terminal architecture option, where the power cabinet and charging terminal are separate units connected by DC cables. This configuration allows the power cabinet to be installed in a technical room while the charging terminal occupies a compact footprint at the parking bay — an important consideration for sites with limited space.
Key specifications for the 240kW model:
- Architecture: Integrated or split-terminal
- Output voltage range: 200–1000V DC
- Maximum output current: 400A (single gun)
- Number of charging guns: 1–2 (configurable)
- Efficiency: ≥96%
Integrated DC Charging Stations: 20kW–40kW
For applications requiring more modest charging speeds, the company offers integrated DC chargers in 20kW, 30kW, and 40kW configurations. These compact units combine the power module, controller, and charging interface in a single enclosure, making them ideal for:
- Small fleet depots (electric delivery vans, electric taxis)
- Workplace parking with dedicated EV spaces
- Residential complexes with shared charging infrastructure
- Rural or remote locations with limited grid capacity
Available in single-gun, dual-gun, and four-gun configurations, these integrated chargers offer flexibility for sites where space is at a premium. The four-gun model allows simultaneous charging of four vehicles, with power shared dynamically based on each vehicle's state of charge and charging capability.
Color Options and Aesthetic Design
All DC fast charging models from Sennan are available in two standard color options: Dark Gray and New Blue. The color choice extends beyond aesthetics — the enclosure finish includes UV-resistant coating for outdoor installations, ensuring color stability and surface integrity over years of sun exposure.
The Dark Gray option provides a professional, understated appearance that blends with urban environments and corporate fleet facilities. The New Blue option offers a more vibrant, modern look that helps charging stations stand out in retail and commercial settings, improving visibility for EV drivers searching for available chargers.
Communication and Network Integration
All DC charging stations in this product line support the Open Charge Point Protocol (OCPP), enabling integration with any OCPP-compliant charging network management system. This interoperability is essential for B2B clients who need to manage charging stations from multiple manufacturers through a unified backend platform.
Supported communication interfaces include:
- Wired: Ethernet (RJ45), RS485
- Wireless: 4G LTE (standard), Wi-Fi (optional), 5G (on request)
- Protocols: OCPP 1.6J, OCPP 2.0.1, Modbus TCP (optional)
The backend management system provides real-time monitoring of charging session status, energy consumption data, equipment health diagnostics, remote firmware updates, and dynamic load management for sites with multiple chargers sharing a limited power supply.
