Tips for choosing an electric vehicle charger considering charging speed requirements

When choosing an electric vehicle charger considering the charging speed requirements, one can start from clarifying the vehicle's charging parameters, selecting power based on the usage scenario, paying attention to the compatibility of charging protocols, emphasizing brand and quality, and considering the heat dissipation design. The following is a specific analysis:

Clarify the vehicle charging parameters: Understand the battery capacity, voltage and maximum allowable charging current of the vehicle. For instance, it may take 18 kilowatt-hours to fully charge the battery capacity of a small or medium-sized electric vehicle. If it is to be fully charged in 6 hours, the power consumption is approximately 3 kilowatts. The power requirements for chargers vary among different vehicle models. Household AC chargers typically range from 3.3kW to 7.2kW, commercial AC chargers from 7.2kW to 22kW, and DC chargers can have a power of over 50kW.

Choose the power based on the usage scenario: If you often charge at home and do not have high requirements for time, you can choose a household AC charger with moderate power, generally ranging from 3.3kW to 7.2kW, and the current is between 8 and 32A. The power of the household slow charging charger that comes with the car is around 3.5kw to 1.6kw. If fast charging is needed, such as during long-distance travel, a DC fast charging station can be chosen. Its power can reach over 50kW, which can significantly shorten the charging time.

Pay attention to the compatibility of charging protocols: Different brands and models of electric vehicles may support different charging protocols, such as Qualcomm's QC3.0, QC4.0, Huawei's FCP, SCP, OV's VOOC, DASH, etc. When choosing a charger, make sure it supports the vehicle's charging protocol to achieve the best charging speed and compatibility.

Pay attention to brand and quality: Choose chargers from well-known brands, such as Philips, Huawei, Xiaomi, UGREEN, Baseus, etc. These brands offer better guarantees in terms of quality, safety and stability. They usually have multiple protection mechanisms, such as overload protection, short-circuit protection, overvoltage protection, overcurrent protection, etc., which can ensure a stable charging process and prevent damage to the vehicle and battery.

Consider heat dissipation design: A good charger should have a good heat dissipation design to prevent the device from overheating due to long-term use. This not only extends the device's lifespan but also ensures charging safety. For instance, some chargers feature fire-retardant PC casings and are equipped with symmetrical heat dissipation holes, which can quickly cool down.
