Overview
The Klitv 120–240 kW DC Charging Pile is built for the highest-demand public and semi-public charging scenarios: charging operation stations, bus charging stations, industrial parks and enterprise campuses, commercial centres, and highway service areas where vehicle throughput is measured in sessions per hour rather than sessions per day.
At 180 kW, the unit delivers a substantial range boost in a 20–30 minute stop for compatible vehicles — enough to serve long-distance travellers and bus or fleet operators on tight schedules. This positions the 120–240 kW range as the right product for operators building highway-adjacent or high-footfall charging infrastructure.
Target Deployment: Highway and Hub Charging
A busy highway charging stop needs to process vehicles continuously through peak periods. High power per gun keeps stop times short and bays free, which is what makes the economics of these sites work: the investment in a larger grid connection is repaid by session throughput rather than by long dwell times.
The same characteristics suit fleet and bus depots, where vehicles rotate through a fixed schedule and predictable turnaround matters more than the lowest capital cost per unit.
Technical Design
Power Architecture
The pile converts a three-phase AC 380 V ±15% input to DC internally, with output adaptive across DC 200–1,000 V. That range covers 400 V passenger EVs and 800 V high-voltage platforms from the same unit. Rated output is specified between 120 kW and 240 kW to match the site’s grid capacity and throughput target.
Driver Interface and Authentication
A 10-inch display supports four startup methods — QR code, RFID card, password, and Auto-VIN. Public and highway sites typically enable QR code and card access so any smartphone-equipped driver can charge without a network membership, while fleet and bus depots use card, password, or Auto-VIN to bill sessions to the correct account automatically.
Protection and Safety
Electrical safety is covered by a multi-layer protection suite:
- Input overvoltage and undervoltage protection with automatic recovery
- Overcurrent and output short circuit protection with instantaneous cutoff
- Insulation and leakage monitoring on input and output circuits
- Lightning surge protection and overtemperature monitoring
- Physical emergency stop, plus connection detection before output is enabled
Connectivity and Management
4G and Ethernet are both built in, so units work equally well on a wired site network or standalone cellular connectivity. Session data, fault alarms, and billing records flow to an OCPP-compatible CMS, which can also issue scheduled start/stop commands, adjust charging profiles, and reboot units remotely.
Installation Requirements
Grid Connection
Each unit requires a three-phase AC 380 V ±15% supply with dedicated upstream protection. Sites installing several high-power units should have the total supply requirement calculated by a qualified electrical engineer, factoring in simultaneous charging scenarios and diversity factors — in many cases a dedicated transformer feed or high-capacity sub-main is required.
Civil and Structural
The unit is floor-standing and mounted on a concrete foundation pad with ground anchor bolts as specified in the installation manual. Because of the higher currents involved, cable cross-section calculations are more critical than on lower-power models; Klitv provides cable sizing guidance with each project quotation.
