Split type charging station (also known as shunt charging station) is a charging device designed to separate the charging machine (rectifier cabinet) from the charging terminal, mainly used in high-power DC fast charging scenarios. The following is a summary of its core features, technological advantages, and application scenarios:
1、 Structure and Working Principle
Separate structure
The split type charging station consists of a rectifier cabinet (main power cabinet) and multiple charging terminals. The rectifier cabinet is responsible for converting AC power into DC power and dynamically adjusting the output power of each terminal through the power distribution module; Charging terminals are distributed in the charging area, providing charging interfaces and human-machine interaction functions.
Modular design
Adopting modular power supply units, supporting flexible expansion. For example, the charging stack system of Hangzhou Juhua Technology can form 120kW, 180kW, or even 240kW models by parallel connecting multiple 15kW modules, and supports simultaneous charging of multiple terminals.
2、 Technical parameters and functional characteristics
High power output
The mainstream split type charging piles have a power range of 120kW to 375kW, with a maximum current of 250A per gun and an output voltage range of 200-750VDC, suitable for fast charging needs of different vehicle models.
Dynamic power allocation
The system can dynamically adjust the power allocation of each terminal according to vehicle requirements, such as optimizing resource utilization and improving overall efficiency when multiple vehicles are charging simultaneously.
intelligent management
Support multiple charging methods such as card swiping, QR code scanning, and remote control through an app;
Equipped with a 7-inch touch screen for real-time display of charging status, battery level, cost and other information;
Equipped with Ethernet, 4G and other communication interfaces, supporting centralized management of pile clusters.
3、 Application scenarios
Public transportation sector
For example, in bus stations, scenic tourist buses, logistics vehicles, etc., due to the concentrated charging time and the need for efficient energy replenishment, the multi gun synchronous charging function of the split charging pile can significantly improve operational efficiency.
Large parking lots and highway service stations
Its high power and modular design are suitable for scenarios with high traffic volume and intensive charging demand, such as highway fast charging stations that can be equipped with a 240kW main power cabinet, supporting simultaneous fast charging of multiple vehicles.
Urban public charging network
The split design is easy to maintain and expand, especially suitable for public charging stations that require long-term operation and technological upgrades.
