How to judge the quality of an electric vehicle charger?

For example, with a 48V charger, the maximum voltage should not be greater than 59.6V. If the voltage is greater than this, the charging may not turn on the light, and the low voltage should not be lower than 55V. If the voltage is lower than this, it will cause insufficient charging and may cause battery loss for a long time. Charging current, such as a 48V20A charger, with a maximum current not exceeding 3A. Greater than 3A may cause the battery to lose water earlier, with a minimum of 2.1A. Low voltage this current causes insufficient charging.
The methods for judging the quality of electric vehicle chargers are as follows:
1. Check the voltage of the charger
For example, with a 48V charger, the maximum voltage should not be greater than 59.6V. If the voltage is greater than this, the charging may not turn on the light, and the low voltage should not be lower than 55V. If the voltage is lower than this, it will cause insufficient charging and may cause battery loss for a long time. Charging current, such as a 48V20A charger, with a maximum current not exceeding 3A. Greater than 3A may cause the battery to lose water earlier, with a minimum of 2.1A. Low voltage this current causes insufficient charging.
2. Check if the indicator light of the charger has turned green
The most critical issue is that the indicator light can turn green after charging is completed. At the initial stage of charging, the battery is usually charged with a large current. The second half of charging is generally Trickle charging. The battery can be fully charged with a small current. The deeper and shallower the discharge of the battery, the greater the number of cycles. Therefore, frequent charging is beneficial for the cycle life, and it is best to choose a charger with high reliability and accuracy.
3. Check if there are any issues with the charger
Once it is found that the charger does not turn green or turns green when charging, it is necessary to check if there is a problem with the charger or if the battery is dehydrated. The discharge and charging ports of the entire battery should be kept clean at all times to prevent copper rust at the contact points, which can cause overheating and damage due to poor contact. To avoid damage to the battery caused by high current. For those with pedals, try to start with your feet as much as possible, do not load too much, accelerate smoothly, and do not start with electricity when sitting in the car.
