The battery charging and discharging tester under the UHV power company can help many power workers conduct various power tests more conveniently.

In chemical batteries, chemical energy is directly converted into electrical energy. Depending on the internal characteristics of the battery, spontaneous oxidation, reduction, and other reactions occur on two electrodes. The negative electrode active material is composed of potential reducing agents and stable reducing agents such as zinc, cadmium, lead, etc. in the electrolyte.

The positive electrode active material is composed of a potential and a stable oxidant stabilized in the electrolyte, such as metal oxides, oxygen or air, halogens and their salts, oxygen-containing acids and their salts, etc Electrolytes are materials with good ionic conductivity, such as acids, bases, salts, organic or inorganic non-aqueous solutions, molten salts, or solid electrolytes.

When the external circuit is turned off, although there is a potential difference (open circuit voltage), there is no current, and the chemical energy stored in the battery is not converted into electrical energy.

When the external circuit is closed, a current flows through the external circuit due to the potential difference between the two electrodes. Meanwhile, within the battery, due to the absence of free electrons in the electrolyte, charging inevitably involves oxidation or reduction reactions at the electrolyte interface, as well as the migration of reactants and reaction products.

Basic principles of battery charging and discussion tester:

measuring principle 

Therefore, the terminal voltage in float charging state cannot truly reflect the performance of the battery.

2. The full capacity discharge test is still the most accurate and effective method for testing the actual capacity of a battery pack. We know that the capacity of a battery pack is equal to the capacity of the battery pack in the battery cell. Therefore, the detection of battery packs can be transformed into the detection of outdated batteries, identifying their capacity, measuring their capacity, and obtaining the capacity of the battery pack.

The main functions of the battery charge and discharge tester are:

1. It has a constant current discharge function for battery packs. Constant current discharge current: 0-30A continuously adjustable, capable of accurately measuring the capacity of a 20V battery pack for power operation.

2. Equipped with intelligent charging function for battery packs. Charging current: 0-30A continuously adjustable, capable of meeting the charging and maintenance needs of the battery pack.
