Does the car charger hurt the battery?

The car charger of Pacific Auto Network is harmful to the battery, and different voltages will affect the life of the mobile phone battery. Mobile phone chargers require different voltages, and the voltages are also different. It can be used occasionally, and long-term use will easily lead to battery loss, that is, the charged electricity is not durable.

1. Car charger is generally used for power supply of car batteries (car 12V, truck 24V), and is widely used in the field of lithium battery charging of various portable and handheld devices, such as mobile phones, PDA, GPS, etc. In-vehicle charging should not only consider the actual demand of lithium battery charging (constant voltage CV, constant current CC, overvoltage protection OVP), but also consider the harsh environment of in-vehicle battery (transient peak voltage, system switching noise interference, EMI, etc.). ); Therefore, the power management IC selected in the vehicle charging scheme must meet the following requirements at the same time: switching power supply chip with high voltage resistance, high efficiency, high reliability and low frequency (conducive to EMI design); Generally speaking, it is a requirement? Leather? .

2. Car charger is an accessory that is convenient for car owners to charge digital products anytime and anywhere with on-board power supply. Some high-end car chargers generally have two USB ports, which can charge two digital products at the same time. These products generally have overload protection, short-circuit protection, high-voltage input protection, high-temperature protection and four-fold safety protection functions to ensure safe use. The car charger can be used at home or in the car, realizing the multifunctional purpose of car charging, direct charging and USB charging.
