With the popularity of electric vehicles, how to charge properly has become the focus of many users. The power supply of an electric vehicle is critical to its proper functioning, and the wrong way of charging can lead to device damage, shortened battery life, and even safety issues.
In our daily lives, we often need to use electric vehicles. Have you noticed some details in the charging process of an electric car?For example, would you rather plug in a power source or a charging port first?
First, let's take a look at the debate about the EV charging sequence. Some people advocate plugging in the battery first, which they believe can reduce the impact on charger surges. Because when the charger is turned on suddenly, there may be a greater starting current, which may damage the charger.
In addition, some EV manufacturers also clearly indicate this charging sequence in their instruction manuals. For example, the instruction manual of the charger for EMMA electric vehicles clearly mentions that the battery terminals should be connected before connecting to the power supply.
But on the other hand, some experts and users advocate plugging in the power supply first.
They believe that this will ensure a stable current** and avoid damage to the charger due to unstable voltage on the battery side. Similarly, charger descriptions from some EV brands such as Giant support this view.
This seemingly trivial issue of order actually has a big impact on the life of the battery. Let's take a closer look at the differences.
First of all, when an electric car is charging, the current is very high. If we connect the power supply first, the charger will start immediately, which will immediately generate a larger current, which is often referred to as a surge impulse current. This current shock can accelerate the loss of the charger and may even cause the charger to burn.
Secondly, if we connect the charging port first and then the socket, we can avoid the above problem. Since the charger has a soft-start process, it can effectively protect the charger from excessive voltage and current shocks.
Therefore, the correct charging sequence should be plugged into the charging port first, and then plugged into the power plug.
In order to guarantee the safety of electric vehicles and extend their service life, it is recommended that all electric vehicle users follow the correct charging sequence: first plug in the battery and then plug it into the power source. After charging, unplug the power source and then unplug the battery. In addition, we need to pay attention to the following:
1.Use the matching charger and cables. Ensure it meets national and local electrical safety standards.
2.Try to turn off most of the functions of the electric vehicle to reduce the battery load.
3.Avoid charging your electric vehicle in hot or humid environments.
4.Regularly inspect the charging equipment and wiring to ensure that they are in good condition.
5.Follow the instructions and precautions of the EV manufacturer.
In short, by following these recommendations and precautions, we can ensure that the charging process for electric vehicles is both safe and efficient, extending the life of the vehicle.
