Under normal circumstances, the fuse tube fuse tube fuse tube fuse tube fuse tube is the charger internal circuit short circuit or over current fault. This is because the charger for a long time in high voltage, high current state, high failure rate of internal devices. In addition, when the grid voltage fluctuates, the surge causes an instantaneous increase in the current in the charger, resulting in a fuse. The solution: Look at the parts on the board first, see if they’re burned out, or if there’s an electrolyte overflow, and it doesn’t seem to make a difference. Then measure the resistance of the power input. If it is less than 20ok Ω, there is a local short in the back end. Then the forward resistance,

In recent years, with the rapid development of data center industry, people pay more and more attention to the security of data center, and the storage battery has become the focus of attention. In order to solve the battery in use, we need to look at it from the point of view of the system, in order to use the battery, power security has a greater help. Figure 1 is the system model of the computer room. When the power is cut off, the battery acts as an emergency power supply. The battery in the database may have more than 90% of the life cycle rarely encountered power failure, but the battery must always be in normal condition, otherwise the battery can not discharge

How to extend the life of electric chargers, in recent years, electric vehicles by virtue of its travel convenience, low-carbon economic advantages into our lives, become people’s favorite short-distance transportation. However, electric vehicles have some disadvantages such as poor durability and frequent charging. If the electric car doesn’t charge in time, it won’t react every day, and the ground won’t work properly. Therefore, charging has become an important part of the daily use of electric vehicles. The technology for electric car chargers is simple. Many car owners know little about chargers. Besides, they don’t pay much attention to routine maintenance. Therefore,

How to calculate the charge quantity of mobile phone charger manufacturer? In fact, a lot of people don’t notice that we don’t need to calculate any charge when using a phone charger. But occasionally, let’s share how to calculate the power of a phone charger? 1. The output of a mobile phone charger is usually direct current. You can use the formula p = Ui, which is maximum output power = rated output voltage × maximum output current. The unit of voltage is volt, the unit of current is ampere, and the unit of power is watt. If the unit of current is Milliamperes, the unit of power is milliwatts.

What is the process of charging and discharging a battery? Battery charging and discharging process: . When the battery is charged, the lead sulfate on the electrode plate is reduced to pure lead acid and lead dioxide acid, the water in the electrolyte is reduced to sulfuric acid, and a large number of electrons return from the positive plate to the negative plate to form charging current. With the increase of charge amount, the more sulfuric acid in the electrolyte, the higher the electrolyte density, the more fully charged, the higher the electrolyte density. But when all the lead sulfate on the board is converted,

Production of electric charger use and troubleshooting, how to use electric car charger! How long does it take to charge the battery car? The correct charge time is to wait for the green light, then float for an hour, then cut the power. Electric car chargers have no overcharge protection, and although the green light is on, the battery is still charging and decomposing, and the water in the battery evaporates because it can’t be turned off. What’s the harm in taking too long a break? Electric vehicle charging should mainly grasp two principles: one is shallow charging.

When using car charger manufacturers should pay attention to matters, with the development of intelligence, the relationship between the car and mobile phone more and more closely. Some cars even support direct control of the phone. Many car owners are used to using in-car chargers in their cars, but you might not think that In-car chargers are a big safety hazard. Use Car charger should pay attention to car charger, first of all, do not plug in car charger before starting, so as not to damage the car charger voltage. Secondly, do not use chemicals, cleaning agents and so on. Cleaning car chargers is very dangerous. During use,

Electric forklift battery charger is the core power of battery charger forklift, because the charging and discharging state of the battery charger is the main link that determines the cycle life of the battery charger, many users tend to neglect the charging part of the battery charging battery. After using the forklift, they connected the battery pack to the forklift charger and left it there. In many cases, the vehicle is already in use even before it is fully charged, which in the long run will accelerate the curing rate of the forklift battery charge and affect its life. Intermittent charging can be said to reduce its cycle times, many forklift manufacturers at noon break, the battery forklift is still only half the capacity,

Analysis of the production of electric chargers N and l meaning, very do not know what electric car chargers N and L stands for? Yongletong Electric car charger factory recently heard a lot about this problem. Many people don’t know what N and L STAND FOR IN ELECTRIC CAR CHARGERS! Today Yongle Tang will briefly analyze the meaning of N and L in the electric vehicle charger. Different manufacturers may be different. Normally, N is a positive number and L is a negative number.

How to choose a charger manufacturer? As the demand for some electronics increases, so does the use of chargers. In today’s market, charger can be said to be multifarious, charger manufacturers are also many, so if we need to find a charger manufacturers cooperation, the overall consideration of this issue will be correspondingly more and more, here in Shenzhen Xingrui technology to teach you how to choose charger manufacturers: First, look at the strength of charger manufacturers, to find a quality assurance of charger manufacturers cooperation, which requires us to find reliable manufacturers, and word-of-mouth and quality can not be less, to Tongxingrui as an example, Tongxingrui is a research and development, production as one of the manufacturers, products based on chargers, in the production of chargers have rich experience, can satisfy the choice charger manufacturer’s need, is the charger manufacturer’s first choice.According to the manufacturer’s charger, current cell phone chargers are original, beautifully copied, and seat recharged.

How to charge a battery properly, in theory, the smaller the charge current, the better. Because the current is very small, the smaller the crystal, the more fully the reaction, the more electricity can be stored. Moreover, the current is small, the battery gives off heat is small, the plate is not easy to deform, the effective material of the plate will not fall off. 10 hours to charge, 100 batteries, 10 hours to charge, 10 currents. , The charging time is slightly higher than the “Battery capacity/charging current”.

What is the cause of the noise from the production of electric chargers? When oneself electric car charges, what reason is charger noise big? How to solve this problem, in fact, there are three reasons, now detailed. Radiator fan bearing oil, if the radiator fan bearing oil, when the charger works, the fan rotation will generate friction noise. Therefore, users only need to open the charger, find out the cooling fan bearings, add lubricating oil can solve the charging noise problem. However, it should be noted that if the bearing rust, the first thing is to remove the rust. The second thing we need to know is that electric cars generate a lot of heat when they charge,
