Due to widely used in the field of portable, handheld devices ,rechargeable lithium batteries, such as: mobile phones, PDA, PS and so on; so the car should not only satisfied with the actual demand for lithium battery charging (general standard: constant pressure CV, constant current CC, overvoltage protection OVP), but also to take into account the harsh environment of car battery (transient spike voltage, system switching noise interference, EMI(and so on), the vehicle charging scheme selection of power management IC must also meet: high pressure, high efficiency, high reliability, low frequency (EMI) switching power supply chip; that is to say stable and firm.
In addition, there are the some warm tips to keep car charger used in correct way:
1.To pull out the plug in time when finish charging.
2.The appropriate temperature for using car charger should be 0-45℃
3.Do not put it in high temperature or low temperature environment
4.Do not use in damp environment
5.Do not store in a humid environment,
6.Keep away from children
7.To avoid the lightning.
Tapered roller bearings are mainly used to bear the radial load-based radial and axial joint load, generally should not bear the axial load alone. This type of bearing is designed so that the inner ring raceway surface, the outer ring raceway surface and the roller rolling surface of the conical surface of the vertex intersect the bearing center line.
