If the charger is not unplugged, will it consume electricity, electric vehicles are one of the household transportation, and they basically have to be charged every day, so what is the impact of the charger not being unplugged.
When the charger fully charges the battery, the charger detects the charging current inside, when the charging current is less than 100MA, the charger converts into a green light, and continues to charge with a small current, when the battery is saturated, there will be basically no current, the charger at this time is equivalent to an open circuit state, no load is connected, and the charger is in a no-load state.
Then when the charger is in the no-load state, it will consume a little electric energy, within 1W, according to different voltages standby power is different, this part of the power is the necessary loss of the charger's own work, which can be ignored.
Then it does not have much impact if it is not pulled out normally, but in order to prevent the charger from being charged and causing fire, it is usually unplugged, and there is no problem if you forget to unplug it occasionally.
I have many years of experience in single-chip microcomputer software and hardware development and circuit maintenance experience, learn circuits, add attention, so that you learn not to get lost, your like is the biggest motivation for me to share experience, if you have any questions, please leave a message to discuss.
