I believe that everyone is very familiar with the car charger. The car charger is used in electric vehicles and cars for charging, showing the characteristics of versatility, portability and fashion. So what is a car charger? Is it clear about its principles and features? Today, the car charger manufacturer will take you to know.
First, what is a car charger?
The car charger is a car charger that is used to charge digital products. Some high-end car chargers generally include two USB ports to charge two digital products at the same time. These products generally have overload protection, short circuit protection, high voltage input protection, high temperature protection, four safety protection functions to ensure safe use. The car charger can also be used at home, and it can realize three-in-one multi-purpose use of car charge, direct charge and USB charge.
The car charger is powered by a car battery (car 12V, truck 24V), and is widely used in lithium battery charging in various portable devices, such as mobile phones, PDAs, GPS, etc. The car charger should consider the actual demand of lithium battery charging (constant voltage CV, constant current CC, over voltage protection OVP), but also take into account the harsh environment of the car battery. Therefore, the power management IC selected by the car charging solution must simultaneously satisfy: a high-voltage, high-efficiency, high-reliability, low-frequency switching power supply chip.
Second, the principle of car charger
Using the socket of the car cigarette lighter as the power source, the power of the cigarette lighter comes from the battery of the car, and the voltage is DC12V. The car charger is a 12V voltage input charger. If you charge the phone, the general output voltage is 5V.
The car charger works like a voltage regulator, but there are some additional features, such as automatic power-down after it is fully charged. The car charger uses a car cigarette lighter as a power outlet to directly charge the phone.
Since the voltage provided by the car is low, only the overload protection circuit is needed inside the car charger. The front end of the car charger socket is designed with a fuse. When the current exceeds the overload protection circuit, the fuse is immediately blown and protected.
Third, the characteristics of the car charger
1. Safety: The car charger has passed the test of international safety performances such as CCC, UL, FCC, CE, etc., and has the guarantee of insurance company, which strongly guarantees the safety of use performance and consumer rights.
2, fashion: For the high-end consumer groups of car owners, the fashion of car chargers is also valued by manufacturers. Generally used ABS material and piano paint process, not only stylish, but also very good.
3. Versatility: The car charger is equipped with four AC adapters: American, British, Austrian and European. It is equipped with car charger, direct charge and USB to meet the charging under different conditions. Dual USB An output interface that can charge multiple electronic products.
