What Is Flexible Charging?
Flexible charging refers to EV charging systems that can dynamically adjust power, charging modes, or configurations based on real-time needs, user preferences, or grid conditions. It enhances efficiency, reduces costs, and improves compatibility with different EVs and environments.
Charging stations can automatically or manually change output power (e.g., 30kW, 60kW, 120kW) depending on:
Number of vehicles connected
Battery SOC (State of Charge)
Grid load conditions
💡 Example: A 240kW station distributes 120kW to one EV, and if a second EV connects, it may split to 120kW + 120kW or 90kW + 150kW.
Multiple charging guns share one power module stack, allowing intelligent power allocation.
Ideal for fleet depots, commercial plazas, or highway stations.
💡 Flexible charging stacks can connect 2–6 dispensers dynamically to optimize usage.
Use of modular power units (e.g., 15kW/30kW modules) allows chargers to scale output up/down or perform hot-swap maintenance without shutting down the entire system.
Works with demand response systems, adjusting power output based on electricity prices or peak hours to lower operational costs.
💡 Flexible charging can pause or slow down during grid stress, and ramp up when energy is cheaper.
⚡ Faster charging based on available capacity
🔄 Multi-vehicle charging with intelligent power distribution
💰 Lower infrastructure costs (one power cabinet, multiple terminals)
🔌 Compatibility with more EV types (e.g., trucks, buses, passenger cars)
🌍 Energy efficiency and better grid integration
Flexible charging is a smart EV charging approach that allows adaptive power control, shared usage, and modular scalability, making it ideal for modern, high-demand EV infrastructure — especially for public fast-charging stations, fleet depots, and energy-conscious operators.
In the context of a Flexible Charging Stack, a Mode 2 Flexible Charger refers to a distributed DC fast charging terminal that operates as a satellite (or slave) unit, drawing dynamic power from a centralized master power cabinet.

How Does A Flexible Charging Stack Dynamically Distribute Charging Power?
A flexible charging stack dynamically distributes charging power by using a centralized power cabinet с intelligent control и modular power units to allocate electricity to multiple EVs in real time based on their individual charging requirements.
The stack contains multiple DC power modules (e.g. 30kW or 40kW each).
These modules can be added or removed to scale total output (e.g. from 240kW to 720kW).
All power is generated here, not in the terminals.
Satellite terminals (DC charging guns) are placed in different parking spots.
They have no internal power units — only control boards and interfaces.
Each EV communicates its current SOC (state of charge), voltage, current, and max charging limit via communication protocols (like OCPP or CAN).
The system gathers this data in real time from all connected vehicles.
The intelligent controller inside the main stack calculates how to distribute the total available power across all terminals.
Example logic:
Car A at 20% SOC → gets 150kW
Car B at 70% SOC → gets 50kW
Car C just connected → gets 100kW
The charging stack uses internal relays and power electronics to route the right amount of power to each terminal.
If a vehicle finishes charging or disconnects, that power is reallocated to other EVs instantly.
Operators can set limits (e.g., max per port: 250kW) or apply rules (e.g., priority charging for buses or fleet).
Energy use can be optimized based on time-of-use electricity prices.
A 480kW charging stack connects to 4 terminals. Here’s a possible real-time allocation:
| Terminal | Vehicle | SOC | Requested Power | Allocated |
|---|---|---|---|---|
| A | Bus | 10% | 240kW | 200kW |
| B | Taxi | 60% | 100kW | 80kW |
| C | Van | 40% | 120kW | 120kW |
| D | New EV | 15% | 180kW | 80kW |
Total: 480kW utilized dynamically and efficiently.
Faster turnaround time for high-demand vehicles
Maximized use of grid power
Lower hardware costs (terminals are lightweight)
Scalable and future-proof
Ideal for fleets, highways, and EV charging hubs
What Is The Difference Between Normal Charging And Trickle Charging?
The key difference between normal charging и trickle charging lies in the charging speed, current level, and use case. Here’s a clear comparison:
| Характеристика | Описание |
|---|---|
| ⚡ Voltage | 220V–240V AC (single-phase) |
| 🔌 Current | Typically 16A–32A |
| 🔋 Power | ~3.3kW to 7.4kW (some up to 22kW) |
| ⏱️ Speed | 4–8 hours for a full EV charge (depends on battery size) |
| 📍 Used in | Homes, workplaces, commercial AC stations |
| ✅ Use Case | Daily charging for EV owners with parking access |
| Характеристика | Описание |
|---|---|
| ⚡ Voltage | 110V–120V (US) or 220V (Asia) household socket |
| 🔌 Current | 6A–10A (very low current) |
| 🔋 Power | ~1.2kW to 2.2kW |
| ⏱️ Speed | 15–30+ hours for a full charge (slowest) |
| 📍 Used in | Emergency use, temporary situations |
| ⚠️ Limitations | Heats up socket, not ideal for long-term daily use |
| ✅ Use Case | Occasional top-up at home without dedicated EV charger |
| Характеристика | Normal Charging | Trickle Charging |
|---|---|---|
| Выходная мощность | 3.3–7.4kW | 1.2–2.2kW |
| Скорость зарядки | Medium | Very slow |
| Safety | Safer (dedicated charger) | Higher risk (household socket) |
| Usage | Regular charging | Emergency or backup use |
| Equipment | Wallbox, AC station | Plug-in adapter or cable |
While trickle charging can be useful in emergencies, it is not recommended for daily use due to:
Slow speed
Higher fire risk from prolonged use of household outlets
Lack of proper monitoring and temperature control
For daily EV charging, a normal AC charger (Mode 2/3) is safer, faster, and more efficient.
