Dual Port Car Charger
Normal questions about Dual Port car charger:
Q1: There is a USB interface on the car, so it is unnecessary to use extra USB port car charger?
A1: Many people think that having a USB port in the car, so it not necessary to buy a USB port car charger.In fact, most of the in-car USB is set for audio data transmission, so the current of USB interface in car is only 0.5A mostly. If the charging current can’t match to standard of device, the devices would get heat.
Q2. What conditions do high-quality dual port car chargers need to meet?
A2: Firstly, the actual demand of Lithium battery charging (constant voltage CV, constant current CC, over-voltage protection OVP) should be considered when choosing a multi USB port or dual port car charger.
Secondly, the harsh environment of on-board battery (transient peak voltage, system switching noise interference, EMI, etc.) should be taken into account.
Therefore, the power management IC selected for the car charging scheme must simultaneously meet the following requirements: switching power chip with high voltage resistance, high efficiency, high reliability and low frequency (conducive to EMI design).
Q3: The battery power decreases when charging by USB port car charger?
A3: Sometimes people like charging while GPS in car. When the amount of electricity consumed in meanwhile is greater than the amount of electricity charged, it would decrease.
