Installing a CCS fast charging station at home is a highly valuable strategic investment for electric vehicle owners, offering unparalleled convenience and efficient charging experience. This guide comprehensively covers every step from preparation to activation, while delving into common challenges, 2025 latest costs, and safety standards. Whether you're a DIY enthusiast or planning to hire professionals, this guide will ensure your installation process goes smoothly.

1. Pre-Installation Preparation: The Foundation for Successful Installation

Before purchasing equipment, thorough preparation is crucial. You need to consider the following aspects:

1.1 Site Assessment

• Determine Parking Location: Choose a fixed parking space close to a power source. Ensure the area is sheltered from wind and rain, with a clear cable routing path. Avoid areas prone to water accumulation or direct sunlight.
• Check Property Regulations: Review relevant rules of the homeowners association/property management. Some communities may require architectural appearance approval or have specific requirements for the charging station's appearance. Prepare to submit a formal application including the installation plan.
• Prepare Ownership Proof: Gather documents such as property ownership proof, parking space lease agreement, and electric vehicle purchase invoice. These are necessary for applying to the power company.

1.2 Electrical Capacity Analysis

• Electrical Audit: Contact a licensed electrician to assess your home's electrical capacity. Most CCS fast chargers require 380V three-phase power. If your home only has single-phase power (220V), consider electrical capacity upgrade or choose lower power options (such as 7kW).
• Subsidy Research: In 2025, many regions still offer incentives for home charging station installation. Check local government websites or platforms like "State Grid Online" to learn about available subsidies for equipment and electrical capacity upgrades.

1.3 Power Company Permit Application

• Online Submission: Use designated platforms (such as "State Grid Online" APP) to submit:
  • Identity documents
  • Parking space location photos
  • Electric vehicle registration certificate or purchase proof
  • Installation plan diagram showing cable routing path
• Communication with Grid Company: Usually within 5-7 working days, an on-site inspection will be arranged for electrical capacity verification. If capacity in your area is insufficient, the grid company will guide you through the capacity upgrade process.

2. Equipment Selection: How to Choose the Right CCS Charging Station

The right equipment ensures safety and long-term reliability. Consider the following factors when purchasing:

2.1 Charging Station Types

• Wall-mounted vs. Standalone: Wall-mounted saves space but requires a sturdy wall; standalone offers flexible installation but typically needs a concrete foundation.
• Power Levels:
  • 7-11kW: Suitable for daily commuting charging (full charge in about 4-6 hours).
  • 22kW and above: Faster speed but requires professional grid assessment and may incur higher costs.
• Smart Features: Prioritize models supporting Wi-Fi, load balancing, and remote control APP for energy management.

2.2 Safety and Compatibility

• Safety Certifications: Ensure the charging station has TÜV, CE, or local safety certifications.
• Additional Features: Look for IP55 waterproof rating, overvoltage protection, anti-theft lock, etc. CCS interface must be compatible with your electric vehicle model.

2.3 Cables and Accessories

• Cable Specifications: Use TPE insulated copper core cables with cross-sectional area ≥3×6mm². Choose UV-resistant models for outdoor installation.
• Grounding Kit: Purchase a complete grounding set (galvanized angle steel, grounding wire, clamps) to meet IEC standards.

3. Installation Process: Step-by-Step Detailed Explanation

Step 1: Formal Power Supply Application

• Submit Complete Documents: After obtaining preliminary grid permission, you will receive a "Power Supply Scheme Response" specifying capacity and costs.
• Meter Installation: Grid technicians will install a dedicated meter for the charging station (usually free under subsidy policies).

Step 2: Wiring and Infrastructure Construction

• Hire Licensed Professionals: In most areas, self-wiring is a violation. Ensure the construction team holds an "Electrician Network Operation License" or equivalent qualification.
• Key Installation Steps:
  • Cable Trench Excavation: Excavate cable trenches with depth ≥30 cm, use 90° angle protective pipes to protect cables.
  • Grounding System: Drive 2.5-meter long galvanized angle steel into the ground and connect to the charging station using 16mm² copper wire.
  • Circuit Breaker Installation: Install an independent 63A/4P circuit breaker ensuring it has 30mA leakage protection.
  • Charger Body Fixation: Install the charging station at a height of 1.2-1.5 meters from the ground, reserving 20 cm surrounding space for heat dissipation.

Step 3: Testing and Activation

• Electrical Debugging: Use a multimeter to verify voltage stability. Test all safety functions (leakage protection, overheating shutdown).
• Electric Vehicle Compatibility Test: Charge your vehicle for 1 hour to confirm connection stability and charging efficiency.
• Final Acceptance: Submit test report to the grid company to complete final power activation.

4. Common Problems and Solutions

Q: Property management refuses installation application, what to do?

• Response Strategy:
  • Cite national electric vehicle infrastructure policies (such as China's "Implementation Opinions on Further Enhancing Electric Vehicle Charging Infrastructure Service Guarantee Capability").
  • Request a mediation meeting with property representatives.
  • Consider using portable chargers as a transition until the issue is resolved.

Q: No three-phase power at home, can it still be installed?

• Solutions:
  • Apply to the power company for electrical capacity upgrade.
  • Use a "three-phase to single-phase converter" (check local regulations in advance to see if allowed).
  • Apply with neighbors to install a shared community charging station.

Q: What are the daily maintenance costs?

• Ongoing Costs: Annual inspection (about ¥200) and cable replacement (if damaged) are typical expenses. Smart charging stations may require small APP service subscription fees.

6. Core Safety Standards

• Cable Management: Avoid cable overload or sharp bends. Use cable protection sleeves for outdoor sections.
• Fire Safety: Equip nearby with Class D fire extinguishers suitable for electrical fires.
• Regular Inspection: Monthly check cable wear, grounding resistance, and circuit breaker function.

7. Efficient Usage Tips

• Load Balancing: If the charging station shares a circuit with other high-power appliances, use a charging station with "smart load management" function to prevent overload.
• Utilize Off-Peak Electricity Rates: Set charging during off-peak hours (such as after midnight) to significantly save electricity costs.
