Analysis of the production of electric chargers N and l meaning, very do not know what electric car chargers N and L stands for? Yongletong Electric car charger factory recently heard a lot about this problem. Many people don’t know what N and L STAND FOR IN ELECTRIC CAR CHARGERS! Today Yongle Tang will briefly analyze the meaning of N and L in the electric vehicle charger. Different manufacturers may be different. Normally, N is a positive number and L is a negative number. Specific analysis of the following charger output plug should be: According to specifications, N = positive power; l = negative power, but in order to make their products unique, some manufacturers have n minus L plus connection, in order not to make a mistake, the first charge is measured with a digital meter, N with a red pen and l with a black pen. The meter should display a set of numbers (no numbers before”-”) to indicate that the red pen is connected to the positive electrode. Otherwise, the red pen is the negative. The electric bicycle charger is specially equipped for the electric bicycle battery charging device! Chargers can be divided into two categories: transformers with and without power frequency (50hz) . Freight three-wheel chargers typically use chargers with power frequency transformers, which are bulky, heavy and power-hungry, but reliable and cheap. Electric Bikes and motorcycles use so-called on-off chargers, which are energy-efficient but easily damaged.

　　The correct operation of a switching power supply charger is to plug the battery into the power supply first, and then to add power when charging. After the battery is fully charged, first cut off the power, and then pull out the battery plug. If you unplug the power before charging, especially when the charging current is very high (red light) , it is easy to damage the charger. Commonly used switch power charger is divided into half-bridge and single pulse, single pulse charger is divided into forward and flyback, half-bridge charger low cost, good performance, often used in negative pulse charger. The single incentive cost is low and the market share is high. That’s what nitrogen and nitrogen mean in electric car chargers.
