The main reasons why the 7KW AC charging station motherboard: has become a household charging station are as follows:

Charging efficiency

• Moderate charging speed: For most household electric vehicles, a 7KW charging station can complete charging within a reasonable time. Generally speaking, an electric vehicle with a battery capacity of 40kWh takes about 5 to 6 hours to fully charge using a 7KW charging station. It will not take as long as a low-power charging station to charge and will not cause damage to the battery due to excessive charging speed.

• Meeting daily needs: Home charging is usually done at night, giving enough time to fully charge the vehicle. The 7KW charging speed can meet the daily travel needs of most household users. Car owners can plug in the charging station after work and travel with a full charge the next morning.

Adaptability

• Wide compatibility: The 7KW AC charging station motherboard has a higher charging power under single-phase 220V power supply, suitable for more than 90% of the vehicles on the market. Whether the vehicle is a sedan or SUV, as long as it supports the AC charging interface (7 holes), the 7KW AC charging station can be used for charging. Car owners do not need to worry about charging due to mismatched power of the charging station.

• Avoiding three-phase power restrictions: Compared to higher power charging stations such as 11KW and 21KW, vehicles often need to support three-phase power charging. However, household electricity environments are mostly single-phase 220V, and installing three-phase power charging stations may face many problems such as application difficulties, property restrictions, and home circuit renovations. 7KW charging stations do not have these restrictions.

Economic viability

• Affordable price: The price of 7KW charging piles is relatively low, and the purchase cost is within the affordable range of most households. Generally, the overall price of a high-quality 7KW AC charging station is around 2000-3000 yuan, and the cost of installation services is usually over 1000 yuan, which is more cost-effective compared to higher power charging stations.

• Reduce electricity costs: Most 7KW charging stations support "scheduled charging", allowing car owners to charge during low hours at night. This not only reduces electricity costs, but also helps balance the power grid load and reduce energy consumption. Long term use can save a lot of electricity costs.

Security

• Stable charging: The 7KW AC charging station motherboard belongs to the AC slow charging station, and its charging process is relatively stable, causing less damage to the battery and helping to extend its service life, reduce battery failures and safety hazards.

• Multiple protection: It has multiple safety protection functions, such as overvoltage protection, undervoltage protection, overcharge protection, overload protection, short circuit protection, leakage protection, and high temperature protection, which can ensure the safety and reliability of the charging process in various complex environments, providing effective safety protection for vehicles and charging equipment.
  
  

Installation convenience

• Easy to apply for an electricity meter: Applying for a 220V electricity meter is relatively easy, as long as the parking conditions meet the requirements, the property management generally does not set too many obstacles, and the installation process is relatively smooth. However, applying for a 380V electricity meter may face numerous approval difficulties and strict restrictions from property management.

• Relatively low requirements for household circuits: 7KW charging piles have relatively low load requirements for household circuits. Generally, existing household circuits only need simple inspections and appropriate adjustments to meet their usage requirements, without the need for large-scale renovation of the household power system, reducing installation costs and difficulties.
