EV Charger

An EV Charger is a device that supplies electric energy to recharge electric vehicles, available in various types like Level 1, 2, and DC fast chargers.

EV Charger
Fast Charging Capability:

Supports high-power output (e.g., 7.4kW-22kW) to significantly reduce charging time compared to standard outlets, adding up to 60 miles of range per hour for Level 2 chargers.

Smart Connectivity:

Equipped with Wi-Fi/4G/5G for remote monitoring, scheduling, and firmware updates via mobile apps, enabling users to optimize charging based on electricity tariffs or grid demand.

User-Friendly Design:

Includes intuitive touchscreens, long charging cables (e.g., 10m), and multi-user support (e.g., RFID/PIN locks) for convenient and secure access in shared spaces.

Universal Compatibility:

Works with all major EV models via standard connectors
(e.g., J1772) or adapters (e.g., for Tesla), ensuring seamless integration across brands.

Safety & Durability:

Features IP54+ waterproof ratings, built-in surge protection, and aerospace-grade materials to withstand harsh environments and ensure long-term reliability.

Future-Proof Technology:

Adheres to protocols like OCPP for interoperability with third-party services, solar systems, or energy management platforms, ensuring adaptability to evolving smart grid ecosystems.

EV Charger

Solar panels, inverters, batteries, and solar power systems.

How to choose the type of charging station?

DC fast charging station: Charges to 80% in 30 minutes, suitable for emergency charging (such as at highway service areas).
AC slow charging station: Takes 6-8 hours to fully charge, more friendly to the battery (suitable for families or residential areas).
Selection logic: Choose slow charging if there is no concern about battery range; choose fast charging if you are going on a long trip or need to charge urgently.

Self-check steps:
Check the power of the charging station (fast charging should be ≥ 60kW).
Confirm that the vehicle’s charging settings are not limited.
Replace the charging station for testing (to rule out equipment faults).
Deep reasons: High grid load, software failure of the charging station, power line problems.

Safety mechanisms:
Electric shock protection, overload protection, short circuit protection.
Emergency stop button (red button, press in case of emergency).
Users should note: Do not place flammable materials within 2 meters of the charging area. Stop charging immediately if you hear unusual sounds or see smoke.

How is the charging fee calculated?

Billing method:
By electricity consumption: Unit price × Charging quantity (e.g. 1.5 yuan per kilowatt-hour).
By time: Service fee × Duration (e.g. 0.5 yuan per minute).
Package: Monthly/yearly discounted package (suitable for frequent users).
Money-saving tips: Charging during off-peak hours (22:00 – 8:00) can save 30% – 50%.

National standard: The new national standard (GB/T 20234) adopts a unified interface, and over 90% of vehicle models are compatible.
Exceptional cases: Older imported vehicles (such as early models of Tesla) require a conversion adapter.
Operation suggestion: Before charging, confirm that the charging gun head matches the vehicle interface (the fast charging gun head is thicker).

Home scenario:
Cost: Slow charging stations are approximately 2,000 – 5,000 yuan, while fast charging stations start at 10,000 yuan.
Payback period: Calculated based on off-peak electricity price of 0.3 yuan per kilowatt-hour and peak electricity price of 1.0 yuan per kilowatt-hour, it takes about 5 – 7 years to recover the cost.
Commercial scenario:
Revenue: Service fee is 0.3 – 0.8 yuan per kilowatt-hour. Profitable if utilization rate is ≥ 15%.
Policy: Some regions provide construction subsidies (such as Beijing offering 30% equipment cost subsidies).

Characteristics of EV Charger

  • 1. Charging Type and Speed
    AC Chargers
    Power range: 3.7 – 22kW
    Charging time: 8 – 10 hours (for household slow charging scenarios)
    Applicable scenarios: Garage at home, parking lot in the community, suitable for long-term charging at night.
    Technical principle: Through the on-board charger for AC/DC conversion, causing minimal damage to the battery.
    DC Chargers
    Power range: 60 – 350kW (breakthrough of 500kW with the new liquid-cooled ultra-fast charging technology)
    Charging time: 80% of the battery charged within 30 minutes
    Applicable scenarios: Service areas on highways, commercial areas, meeting emergency charging needs.
    Technical advantages: Directly output high-power DC electricity, bypassing the on-board charger, resulting in higher charging efficiency.
  • 2. Intelligent Functions and User Experience
    Remote Monitoring and Wi-Fi Connection
    Users can view the charging status and energy consumption data in real time through the mobile APP and adjust the charging plan.
    Example: The Emporia Level 2 EV Charger supports remote control. Users can set it to automatically charge during the low-price period to save costs.
    Smart Scheduling and Peak-Valley Electricity Pricing Strategy
    The charger can adjust the output power dynamically according to the grid load, guiding users to charge during off-peak hours to reduce electricity costs.
    Data Support: Through smart scheduling, users’ electricity expenses can be reduced by 30% – 50%.
    Safety Protection Mechanism
    Insulation Detection: Detects insulation faults within 30ms and cuts off the circuit (IEC 61851 standard).
    Emergency Stop Protection: Equipped with a red emergency stop button, which can stop charging immediately in emergency situations.
    Lightning Strike Protection: Ensures the charging process is not interfered by lightning strikes.
    High-end Models: Some products are equipped with smoke detection and automatic fire extinguishing devices, building multiple safety protections.
