As EVs proliferate, charging and battery-swap stations are being deployed rapidly in modular, prefabricated form. A typical station runs hundreds of kW—even MW-scale—while battery clusters in swap stations charge and discharge simultaneously, creating concentrated, highly fluctuating heat loads. How to keep such high-power sites stable and reliable? Treat thermal management as an integral part of the prefabricated cabin design.
1. Heat-load challenges of charging & swap stations
- High power density: charging modules and power-distribution units release heat in concentrated spots, with local hotspots reaching several kW;
- Severe fluctuation: random vehicle connections swing load between 0 and peak, making temperature spike and drop sharply;
- Harsh environment: wide annual temperature swings, strong solar radiation, dust and salt mist—ordinary AC cannot cope;
- Continuous duty: 7×24 uninterrupted operation; downtime hits revenue, so reliability is paramount.
2. Why whole prefab cabin + integrated enclosure AC
The traditional approach—assemble on site, then add AC later—often ends with a sealed cabin whose IP55 is broken by split-AC refrigerant pipes. Haocheng's approach: deliver the power prefab cabin / energy-storage prefab cabin as a whole, and equip it with HCK integrated enclosure air conditioners—indoor heat exchange and outdoor dissipation in one unit, never breaking the cabin seal, fully matching IP55. Importantly, what we supply is an enclosure air conditioner (wall-mounted, all-in-one), not a split AC.
3. Zoned cooling and linkage
Zone by heat source: charging-module zone (high power) gets HCK-5000A/7500A high-airflow units; battery/storage zone gets energy-storage prefab-cabin dedicated enclosure AC; control/secondary-equipment zone gets compact HCK-3000A. Every HCK enclosure AC supports RS485/Modbus, reporting temperature and status to the gateway for station-wide centralized monitoring and linked start/stop—avoiding both over-cooling waste and over-heating shutdown.
4. Sizing reference (by station scale)
| Station type | Typical heat load | Recommended HCK model | Qty |
|---|---|---|---|
| Small charging station (≤300kW) | 1000–2000W | HCK-3000A/5000A | 1–2 |
| Medium charging station (300–800kW) | 3000–6000W | HCK-5000A/7500A | 2–3 |
| Battery-swap station | 4000–8000W | HCK-7500A | 3–4 |
| Solar-storage-charging integrated station | 6000W+ | HCK-7500A + energy-storage prefab cabin kit | 4+ |
5. Whole-cabin + cooling integrated delivery
- Done in one shot: cabin and AC co-designed, interfaces pre-installed, ready to run on arrival;
- Unified after-sales: you deal with only one supplier—Haocheng—for spares and accountability.
Reliability of a charging/swap station is half in the cabin, half in the cooling. Choosing the right dedicated enclosure AC is easier than retrofitting later.
