When using an electric vehicle charger for fast charging at a highway service area, the following techniques can be adopted to improve charging efficiency and ensure the smooth progress of the journey:
First, plan and prepare in advance
Query charging pile information:
Before departure, use a map application or a charging network platform (such as the “State Grid Online” App) to check the distribution of charging piles at the expressway service areas along the way, and understand the number, type (fast charging or slow charging) and operational status of the charging piles.
Plan the charging route:
According to the distribution of charging piles, plan the charging routes reasonably to ensure that the service area can be reached in time for charging when the battery power is low.
Prepare charging equipment:
Make sure that the charging interface of the electric vehicle is compatible with that of the charging pile, and carry the necessary charging equipment and cables.
Second, choose the right time to charge
Avoid peak hours:
During holidays or weekends when traveling, there may be a peak in charging at the service area. To avoid queuing and waiting, it is recommended to charge during free time outside peak hours, such as lunch or dinner time.
Charge during breaks:
During the charging process, you can take advantage of this time to rest or handle other matters, such as having meals, taking a break, or checking the vehicle’s condition.
Third, master the fast charging skills
Give priority to choosing fast-charging piles:
Fast charging piles can usually charge the battery to about 80% within 30 minutes, making them suitable for scenarios where the battery stays for a short time. If time is limited, fast-charging piles should be given priority.
Pay attention to the charging power
Select the appropriate charging power based on the battery capacity of the vehicle. Although high-power charging can increase the charging speed, frequent use of fast charging may have a certain impact on battery life. Therefore, in non-emergency situations, it can be used in combination with slow charging piles.
Avoid overcharging:
Generally speaking, charging the battery to 80% to 90% is sufficient to meet most driving needs. Overcharging not only increases the charging time but may also cause damage to the battery.
Correctly connect and disconnect the charger:
When connecting the charger, make sure the charging interface is securely connected to avoid reduced charging efficiency or damage to the charger due to poor contact. After the charging is completed, disconnect the charger in the correct sequence. First, unplug the AC power plug, and then disconnect the output plug of the charger.
Fourth, pay attention to safety matters
Comply with charging rules:
During the charging process, one should abide by the rules and instructions of the charging station to ensure the safe and smooth progress of the charging process.
Pay attention to the charging status
During the charging process, attention should be paid to the charging status of the vehicle, such as charging current, voltage, and battery capacity, to ensure the normal progress of the charging process.
Deal with abnormal situations promptly:
If any abnormal situation is found during the charging process (such as charger failure, vehicle failure, etc.), charging should be stopped immediately and professional personnel should be contacted for handling.
Fifth, other suggestions
Carry a backup power supply:
If the journey is long, it is recommended to carry a backup power source or a mobile power bank to deal with unexpected situations.
Keep the vehicle in good condition:
Regular maintenance and inspection of electric vehicles should be carried out, including the cooling system, charging system and the battery itself, etc., to ensure that the vehicle is in good condition and improve charging efficiency.
By applying the above techniques, you can efficiently use electric vehicle chargers for fast charging in highway service areas, ensuring smooth and unobstructed long-distance driving.
