How to monitor the charging progress during the use of an electric vehicle charger

During the use of electric vehicle chargers, monitoring the charging progress can be achieved through the following several ways:

1. Check the display screen of the charging pile

Most public charging piles are equipped with display screens. After connecting the charging gun and starting the charging pile, car owners can obtain real-time information such as the charging status, power, the amount charged, and the remaining charging time. The display screen usually presents these data intuitively in the form of numbers or progress bars, making it clear at a glance for car owners. Different models and brands of charging piles may vary in the layout and presentation of their display screens. Careful observation is necessary when using them.

2. Use a mobile phone APP

Many electric vehicle brands offer official mobile apps. Car owners can download and install these apps, register and log in, and bind their vehicle accounts to check the charging progress anytime and anywhere. In the APP, car owners can clearly see detailed data such as the current battery power percentage, charging speed, and remaining charging time. Some apps also offer functions such as scheduled charging, timed charging, and charging reminders, making it easier for car owners to manage the charging process.

Download and Installation: Search for and download the official APP of the corresponding brand in the app store of your smartphone, and follow the prompts to install it.

Login and Binding: Open the APP, log in with your vehicle account, and select the vehicle you want to view from the vehicle list to bind it.

Check the charging progress: On the main interface of the APP or the charging status details page, view the detailed information of the current charging status.

3. Check the in-car display screen

Most electric vehicles have a dedicated charging status display area on the central control screen or instrument panel inside the vehicle. Car owners can obtain key information such as the current battery percentage, estimated full charge time, and charging power here. This method is suitable for car owners to check while waiting in the car for charging.

4. Utilize the Battery Management System (BMS

The battery management system (BMS) of electric vehicles can monitor key parameters of the battery in real time, such as power, voltage, and temperature, and accurately estimate the remaining power and charging time through these data. Although the BMS itself does not directly display the charging progress, it establishes a communication connection with the control module of the charging pile to achieve real-time data transmission. The charging pile acquires the remaining battery power information from the BMS system and then displays the remaining charging time on the display screen of the charging pile or the accompanying APP.

Precautions

Data accuracy: As the charging progress is affected by various factors such as battery status, charging power, and ambient temperature, the actual charging time may deviate from the estimated time. When car owners check the charging progress, they should pay attention to the changes in real-time data.

Network stability: When using a mobile phone APP to check the charging progress, it is necessary to ensure the stability of the mobile phone network. Unstable network may lead to data delay or inaccuracy.

Compatibility of charging piles: Charging piles of different brands and models may vary in functions and display methods. Before using a charging pile, car owners should carefully read the user manual to understand its specific operation methods and the way to check the charging progress.

Through the above several methods, car owners can conveniently monitor the charging progress of electric vehicles and ensure the smooth progress of the charging process.
