Electric Battery Charger

The high-frequency electric charger uses a microprocessor (CPU chip) as the processing control center. It burns the complicated hardware analog circuit into the microprocessor and controls the operation of the UPS in the form of a software program. Therefore, the volume is greatly reduced, the weight is greatly reduced, the manufacturing cost is low, and the selling price is relatively low. The inverter frequency of the high-frequency machine is generally above 20KHZ, but the high-frequency charger has poor tolerance under harsh power grid and environmental conditions, and is more suitable for the environment with stable power grid, less dust, and suitable temperature and humidity. Compared with the industrial frequency charger, the high frequency charger: small size, light weight, high operating efficiency (low operating cost), low noise, suitable for office places, high cost performance (low price under the same power), impact on space and environment Small, because the transformer of the power frequency charger isolates the mains from the load, in the harsh environment of the mains, the power frequency charger can provide safer and more reliable protection than the high-frequency function. In some occasions such as medical treatment, the charger is required to have isolation device. Therefore, for industrial, medical, transportation and other applications, the power frequency charger is a better choice.

1. High-frequency charger are reliable. The world-renowned charger manufacturers focus on high-frequency chargers in terms of technology selection and future development trends. Chargers of 30KVA and below are mainly high-frequency chargers. The dynamic response speed of the charger load is fast, the energy density is high, the volume is small, the noise is small, and the price is low. Especially, the high-frequency charger can do input active power factor correction, which represents the future development trend of green power.

2. Most of those who question the reliability of high-frequency chargers are domestic small-brand small charger manufacturers. Their own competitiveness is limited, so in the process of developing high-frequency chargers, they cannot improve the performance of the fuselage due to the limitation of the development level, so they can only improve the industrial frequency chargers on the basis of the introduction of the technology of Taiwan manufacturers in the late 1980s. A very important point in the development of power frequency charger to high frequency charger is the anti-interference problem of high frequency switch control.

  Develop

With the continuous development of technology, many new technologies and new concepts in the field of computer and power electronics have been introduced into the charger industry. The charger has made significant progress compared with the previous products in terms of main performance, appearance size, adaptability to the field environment and reliability. Some indicators are even qualitative leaps. For large and medium-sized chargers More so.

    Electric pallet trucks, electric forklifts, electric pallet trucks, electric lift trucks, electric tour buses, electric boats, painting boats, locomotives, etc.

    The high-frequency intelligent battery charger needs to cut off the charging current in a timely manner, otherwise the battery will have a large amount of gas, water loss and temperature rise and other overcharge reactions, which will endanger the service life of the battery. Therefore, it is very necessary to monitor the charging status of the battery at any time to ensure that the battery can be fully charged and not overcharged. The main control methods for stopping charging are:

    The structure of the monitoring network of the high-frequency intelligent battery charger is analyzed. The communication application layer protocol of CAN and GPRS of the communication network of the monitoring terminal is analyzed in detail. Its CAN network protocol has wide versatility, and GPRS has less traffic, which can be extended to other fields of automation.

●The relative humidity of the air is not more than 85% (when the medium temperature is 20℃±5℃)

●Where there is no conductive dust, the battery charger is explosion-proof, and there is no dangerous environment.

●An environment that does not contain gases and vapors that can corrode metals and damage insulation

●Where there is no rain or snow

●Places without severe vibration and shock

●It should be placed in a ventilated and dry place, avoiding high temperature, dust and corrosive gases

●Confirm whether the input voltage of the charger is consistent with the grid voltage where it is located

●Confirm that the charged battery matches the specifications of the charger

●To ensure the normal operation of the charger, keep the air around the charger unobstructed
