Phone Charger Reliability And Stability
Phone Charger is the use of high-frequency power technology, the use of advanced intelligent dynamic adjustment charging technology. Frequency machine is based on the traditional principle of analog circuit design, the machine internal power devices (such as transformers, inductors, capacitors, etc.) are relatively large, generally in the larger load with a small noise, but the model in the poor Of the environmental conditions of the grid resistance to strong resistance, reliability and stability than the high frequency machine strong.
Phone Charger (Phone Charger) according to the design circuit operating frequency to points, can be divided into frequency machine and high frequency machine. Frequency machine is based on the traditional analog circuit principle to design, the machine internal power devices (such as transformers, inductors, capacitors, etc. ) Are large, generally in the load with a larger operation there is a small noise, but the model in the harsh power grid environment resistance to strong resistance, reliability and stability than the high frequency machine strong.
The high-frequency machine is a microprocessor (CPU chip) as a processing control center, is the complex hardware analog circuit burned in the microprocessor, the software program to control the operation of the UPS.Therefore, the volume greatly reduced, Weight is greatly reduced, the manufacturing cost is low, the price is relatively low. High frequency machine inverter frequency is generally above 20KHZ. But the high frequency machine in the poor power grid and environmental conditions, poor tolerance, more suitable for the grid is stable and dust Less, warm / humidity suitable for the environment.
High frequency machine and frequency machine comparison: small size, light weight, high operating efficiency (low operating costs), low noise, suitable for office space, cost-effective (under the same power, low price), space, environmental impact Small, relatively speaking, high-frequency Phone Charger on the copier, laser printer and motor-induced shock (SPIKE) and transient response (TRANSIENT) vulnerable, due to the frequency of the transformer to the mains and load isolation, In the harsh environment, the frequency machine provides more safe and reliable protection than the high frequency function. In some occasions, such as medical treatment, the Phone Charger is required to have the isolation device. Therefore, for industrial, medical and transportation applications, The choice of the two options according to the customer's different installation environment, load conditions and other conditions to consider.
Charging is an important step in using a rechargeable battery. Appropriate and reasonable charging to extend battery life is very good, and improper charging will have a great impact on battery life. Lithium batteries are basically based on individual products are individually packaged, each other is not common, so each product also provides their own charging equipment, not common, in use as long as the use of their own instructions can be used.
Fast charge and slow charge
For example, a 5 Ni-MH battery capacity of 1200mAH, while the other section was 1600mAH. The capacity of a battery is called 1C. In the charge, the charging current is less than 0.1C, called trickle charge. Trickle charge can fill the battery very full, without harming the battery life, but the time spent with trickle charge is too long, so rarely used alone, but with other charging methods used in combination.
Charging current between 0.1C-0.2C, called slow charge. Charge current greater than 0.2C, less than 0.8C is fast charge. And when the charge current is greater than 0.8C, called ultra-high-speed charging.
However, 1C is a logical rather than absolute value, so the fast charge and slow charge based on 1C is also a relative value, just as the 200mAH charge current is slow charge for 1200mAH batteries and fast charge for 700mAH batteries.
1, waterproof moisture. As an electronic product, inadvertent water or prolonged exposure to the humid air when not in use, will be its internal electronic components caused by varying degrees of corrosion or oxidation.
2, anti-fall shock. Mobile phone Charger is actually a fragile component, the internal components can not afford to beat. In particular, to prevent the use of the process accidentally landing. Do not throw, beat or shake the Phone Charger. Roughly treating the Phone Phone Charger will destroy the internal circuit board
3, anti-strong chemical products. Do not use strong chemicals, cleaning agents or strong detergents to clean the Phone Charger. Clear the appearance of the Phone Charger can be stained with cotton a small amount of anhydrous alcohol scrub.
4, when cleaning static. Regularly clean the Phone Charger and charging the interface. When cleaning, use a damp cloth, or an antistatic cloth. Do not use dry cloth (electrostatic charge).
5, anti-cold and heat. Do not place the Phone Charger in places where the temperature is too high. High temperature will shorten the life of electronic devices, destroy the Phone Phone Charger, so that some plastic parts deformation or melting. Do not store the Phone Charger in a cool place. When the Phone Charger in the cold environment, the internal temperature, the Phone Charger will form a moisture, destroy the circuit board.
