Introduction to the power tool 2V300AH lithium battery typeMatters need to pay attention to when EPS power replacement

The EPS power system mainly includes a rectifier charger, a battery pack, an inverter, an interpolation device, and a system controller. The EPS power supply is good, it can be used to power the power when it is critical, and the battery is an important core issue. Therefore, the battery is replaced in time after the battery is used.
First, the battery selection requirements:
1. The brand of the battery cannot be lowered. The newly replaced battery quality should be higher than the original battery quality, because there is now a lot of battles on the market, the quality is also different, the life of the life is different, and the price between the batteries is very different;
2, the amount of time of the new battery cannot be changed, the shape size should not be more than the original battery.
3. The battery capacity of the emergency power distribution cabinet is not reduced. In the design before construction, the size of its capacity is based on the theoretical data required by the owner. After the project is well-established, according to the current actual demand capacity, there may be some big wealth in the capacity of the emergency power distribution cabinet, if Reducing the battery capacity will increase trouble for future work.

The Huizhong lithium battery has a high-spirited characteristics of the discharge platform, high safety, long life, and excellent low temperature performance.
4. The brand of the battery cannot be lowered. Because now there is a lot of battles in the market, the quality is also different, and the life of life is also different;
5, battery temperature detection. Check the battery surface temperature and check the battery. * Good to touch the temperature of the battery, prevent accidents that may have exploded during testing.
6, battery internal resistance detection. For each battery, the battery is detected, the unqualified battery is replaced, the battery needs is different, the internal resistance is different, the larger the time, the larger the internal resistance, the same power supply cabinet The internal battery is about ¡À 3%. If the internal resistance is large, the battery will be easily heated due to the unevenness of the internal resistance, and the battery is easily drummed.
7, battery installation. The battery installation includes the removal of the old battery, and the old battery should be safe and reasonable after the old battery is removed, and the transportation is cleaned up in the future. At the time of installation, you should pay attention to the intermediate health, packing box and waste in time.
According to the disclosure, “tungsten” is a metal material that plays an extremely important role in important industrial industries such as automobile and arms weapon manufacturing. Our China is not only known as this metal material, but also a national “tungsten” production capacity * large country, far exceeding 10 times more than Vietnameses ranking second in capacity. (The information from the US Geological Survey), in the perspective of the reporters and many Western financial experts in Bloomberg, the price of “tungsten” in the international market has increased in the international market, and there is China * Direct relationship, especially the environmental protection measures “of China since the history of” history “this year.
Second, the test after the battery is installed:
1. Firstly, you should check whether the components of the EPS power supply are intact, such as rectifier charger, inverters, various megapons, dual power mutual investment (ATSE is self-vying) should be prominesed.
2, perform EPS power cabinet machine debugging. If the emergency power supply is a dual power input (ATSE is self-fluidized), the dual power supply portion is transmitted in the case of disconnecting the EPS power input switch and the battery switch (insurance). The main electric input switch is closed, and the ATSE should enter the main power supply mode, and the backup input switch is closed. At this time, the main electric input switch is disconnected, and the ATSE should be able to switch to a backup power supply. After the main electric input switch is closed, the ATSE should be able to automatically restore the main electric power supply, and the status indicator of the device during this process should work. After determining that the ATSE is working properly, the EPS input switch and the battery switch (insurance) are closed. After the input voltage and charging current are normal, the load switch is sequentially closed, and the three-phase current is measured, and the primary power-on process can be completed.
3, simulate switching. After the power supply of the emergency power supply, analog switching, namely, the city’s electric / emergency switching to verify the emergency power supply equipment * as an important function. Analog switches can be implemented by one of the following:
First disconnect the ATSE’s backup switch, and then disconnect its main input switch. At this time, the emergency power supply shall be able to switch to emergency power supply. Recovery to network power supply only needs to close the above switches, the emergency power supply should be switched to mesh power supply.
Huizhong – Huizhong brand OPZV tube colloidal battery main components: Polar material 1 # Electrolysis lead, separator is an imported partition for the United States, colloid is German import colloid.
Third, the maintenance of the battery is maintained.
Key to strengthen the maintenance work, the maintenance personnel check the EPS power cabinet battery in the inspection equipment, and the temperature is generally different from room temperature in the case of charge, and only the battery is in a state of charge, the temperature ratio of the battery The room temperature is slightly higher. The inspector must be registered in the inspection record during measuring the battery temperature. When the battery temperature occurs, it will be found in time, and the processing of replacement batteries will be made in time to prevent other problems in the battery.
