Here we need to explain to users that the charging pile does not charge the electric vehicle with empty electricity. The charging pile equipment only provides a power supply, which also uses normal household voltage of 220V. It has the same charging principle and essence as other ordinary socket charging. The charging pile is just a device that controls the switch of the socket. The charging process actually needs to be controlled by the user's own charger. The device itself will not reduce the voltage and limit the current. The charging effect depends on the user's charger and battery.

① Temperature influence: As the weather gets colder, the battery activity will decrease to a certain extent as the temperature decreases. Most electric vehicles are lead-acid batteries. Lead-acid batteries can be stored normally and discharged to a large extent at an ambient temperature of 25°C. However, at 15°C, the charging and storage capacity of the battery is only 2/3 of the normal environment, or even lower. So this will give everyone two feelings: the battery life is shortened and the running is boring. ?② Scenario impact: Most charging piles are distributed in underground garages, carports, and outdoor public areas. In winter, these places are obviously colder than indoors. Combined with the first point, the colder the ambient temperature, the less conducive to battery charging. Therefore, it is easy to cause the feeling of "not as powerful as charging at home". ?③Adapter impact: Many electric vehicle chargers do not judge whether the electric vehicle is fully charged based on parameters such as the actual charging current and voltage, but simply use a timer. For example, when the current drops to less than 1A for 2 hours, the current is forcibly cut off (the time varies, until the battery voltage drops and then resumes power). Without judging whether the overall charging has entered the trickle-float charging stage. When the electric vehicle charger actively cuts off the current, it will trigger the charging pile's judgment mechanism, thinking that the plug has been unplugged or the car is fully charged, so the charging pile actively ends charging. When the electric vehicle charger resumes work, there is no more power input. When charging at a normal socket, since the socket will not maintain power supply according to the current charging conditions, when this type of electric vehicle charger resumes work, it can continue to have power input, thus ensuring that there is enough power to charge into the battery. ? ④ Comprehensive impact: The actual situation of the electric car battery may be different from what you imagine. Long-term non-charging, battery failure, connection line failure, etc. may cause the battery to not be calculated as a normal charging battery. In actual use, the battery may not be as durable as imagined.
