How To Choose EV Charger
Currently, the most common types of charging piles available on the market can be divided into three categories: AC charging piles, DC charging piles, and portable mobile AC charging piles. Among them, AC charging piles are the most common for home use, and most cars come equipped with this type of charger from the factory. DC charging piles, on the other hand, are mainly used by charging stations and third-party fast-charging providers. Portable charging piles are convenient to use and do not require a separate electricity meter, but they have a lower charging power. They are mainly used in scenarios where temporary charging is needed, serving as a supplement to the main charging method.
AC charging piles are intended for emergency use or for car owners with home parking spaces who are not pressed for time. Typically, it takes more than six hours to fully charge a car, so it is not suitable for quick turnaround use.
The power of AC charging piles is limited by the load capacity set by the power supply department, with single-phase power usually capped at 7kW and three-phase power at 21kW. For residential parking spaces, property management companies typically only provide single-phase power, which is limited to 7kW. The portable charger that comes with the car usually has an even lower power output, generally around 3.5kW, which aligns with the standard installation of most residential sockets.
The National Reference Standards for AC Charging Piles Have Established Three Modes, Ranging from Simple to Complex Technological Implementations
● The First Mode is quite basic and directly connects the 220V AC power to the charging port. This mode does not include any control over parameters such as charging voltage, current, or temperature. Everything is controlled by the car's internal charging management system.
● The Second Mode has basic control functions, usually limited to a 3.5kW charging output power. Most of these charging piles are designed as portable chargers.
● The Third Mode includes comprehensive management and control of the charging process, supporting both single-phase and three-phase systems. The power output can reach 7kW for single-phase and 21kW for three-phase charging.
Among these three types of charging equipment, the first mode lacks any safety protection, so reputable manufacturers have mostly ceased production. Only a few unscrupulous manufacturers continue to sell these inferior products, so car owners should thoroughly understand what they are buying before making a purchase.
Based on Our Understanding of Charging Pile Design and Research, Here Are Some Suggestions for Choosing AC Charging Piles:
Choose a Charging Pile Compatible with Your Car First, understand your car's charging power and check whether the charging pile's power matches it. Most of the current mainstream new energy vehicles support a charging power of 32A, 7kW. Therefore, when purchasing a charging pile, you should choose one that supports 7kW. The replacement frequency of new energy vehicles is higher than that of traditional fuel cars. It is possible that in the near future, you may replace or add a new car that supports 11kW, so you can also consider installing an 11kW charging pile to cover future needs.
Ensure the Product Has Safety Protections Since charging products are closely related to personal safety, the chosen charging pile must have adequate safety protections. For example, it should be equipped with appropriate leakage, over current, and lightning protection, which can protect electrical devices from damage due to natural weather conditions to some extent. An emergency shutdown button is particularly important; if an accident occurs during use, you can quickly activate the switch to prevent safety incidents.
Generally speaking, the quality of charging piles and after-sales service from reputable manufacturers are more reliable. The warranty period typically ranges from 2 to 4 years, and the after-sales service and management are usually more standardized.
In terms of user experience, charging piles can generally be managed via a car control app. Features such as checking the charging pile's operating status, scheduling charging, remote control, remote upgrades, and authorization are very useful for car owners. However, these functions are only available on charging piles that support internet connectivity. Most home charging piles on the market only support WiFi or Bluetooth connections, allowing users to perform charging operations from a short distance using their mobile phones.
