Three Stages of Electric Vehicle Charging
To understand if the charger is still charging after it turns green and when it is unplugged, we first need to understand the battery process. At present, most of the lifepo4 smart charger used in batteries are three-stage chargers, which are divided into three stages when charging the battery, namely constant current charging, constant voltage charging and trickle charging.

When the Lifepo4 Smart Charger is not charging, we simply plug it into the socket, will this behavior cause power consumption? The answer is of course!
After scientific testing, the charger will generate current even when there is no load on it. The charger is a transformer and ballast device, and it will always work as long as it is connected to electricity.
As long as the charger is not unplugged, the coil will always have current flowing through it and will continue to work, which will undoubtedly consume power. Although the power consumption is not much, but the accumulation adds up to a lot of power wasted.
