Battery Manufacturing Terminology
The channel operates with the current set by the user. If the current of the step is not within the range of set current ± absolute value / set current ± set current *, the current out of tolerance protection condition will take effect and the channel will enter the protection state.
When the temperature exceeds the threshold, the protection function is enabled to prevent abnormal operation or faults.
A system for battery sorting, capacitance separation and charge/discharge testing.
During the battery charging and discharging process, the electric energy released by the battery discharge is recovered and supplied to the adjacent channel or other nearby test instruments for use, thus achieving the purpose of energy saving.
Grid feeding efficiency refers to the efficiency of charging and discharging equipment to return energy to the grid. It represents the extent to which energy is lost when it is transferred from charging and discharging equipment to the grid. The feed efficiency is usually expressed as a percentage and depends on the design and operating status of the equipment.
The maximum power that an instrument can bear, usually the actual total power of the device equal to its rated power.
The ratio of active power to apparent power. It reflects the utilization efficiency of useful power in the energy conversion process of the equipment.
Current stability refers to the ability of the current output to remain stable for a certain period of time. It measures the ability of a current source or current output device to provide a stable current and reflects the degree of fluctuation in the current output.
The interval at which data is extracted from a continuous signal and recorded.
The test is performed when the test instrument is disconnected from the upper computer.
Overfrequency protection refers to the protection action triggered when the frequency of the power system exceeds the set upper limit. This is usually caused by a light power load or excess power supply, which can cause problems such as overheating, damage, or system crashes. Overfrequency protection quickly cuts power or takes other measures to stabilize the system frequency and protect critical equipment.
Underfrequency protection takes measures to balance supply and demand, such as automatically starting backup generators or adjusting power system parameters to ensure that the system frequency returns to a safe level.
When the line voltage is reduced to the critical voltage, the action to protect the appliance is called undervoltage protection, mainly to prevent the equipment from receiving damage due to overload.
It is mainly used in inverters and frequency converters and other equipment to achieve energy saving effect by optimizing the energy conversion process.
Four-wire connection is a circuit connection method commonly used for measuring voltage and current in a circuit. It utilizes four wires for the connection, consisting of two voltage leads and two current leads.
Implement charge and discharge protection for a series battery pack to ensure that the voltage difference between individual cells is below a set limit, and achieve uniform charging of each cell in the battery pack.
