Equipment main features

• Function descriptions
  • The equipment is mainly used to test battery charging and discharging and related battery characteristics, and the test channel is completely independent. Through software programming control, customers can arbitrarily program the current and voltage within the range to charge and discharge the battery, start and bind the test data according to the barcode, carry out product information tracking management, and monitor the battery data changes in real time during the battery charge and discharge process.
  • Safety protection: The device has the functions of anti-reverse output connection, abnormal voltage sampling line, abnormal current test line detection and protection functions. In the case of reverse battery connection, the channel cannot input and output current normally; when the voltage sampling line falls off or is disconnected, the current When the contact is not good, the equipment detects the abnormality in time and suspends the test channel. It has power-off protection, over- current protection, over-voltage protection, over-temperature protection, which can ensure test safety
  • Processing steps: You can customize variables to participate in programming, realize a variety of combined test schemes, and support multiple loop nesting.
  • Single point independence: Each channel has an independent programmable constant current source and constant voltage source, and the test step can be independently set to run
  • Interruption: In any case, such as a sudden power failure, communication interruption or other abnormal reasons, the channel stops, the next time the conditions are restored, the process step has the automatic connection and forced connection operation functions.
  • Abnormal capture: It can accurately capture the details of voltage and current changes. If the current and voltage changes exceed a certain range, the device can automatically generate alarms and suspend testing.
  • Record tracking: It has the record function, including operation records and abnormal records during the entire test process, which can be used for traceability and abnormal query of the test process.
  • Equipment and computer interface: The equipment and computer use Ethernet interface, which can ensure the stability and real-time performance of long-distance data collection, and can remotely monitor the operation of the upper rack of the workshop activation equipment in real time through the office network.
  • Data recording and processing: The main channel can be equipped with any auxiliary temperature or voltage channels for real-time monitoring of battery temperature or voltage, and synchronous display of total voltage, total current, total capacity, auxiliary channel temperature, etc.
  • Curve analysis and processing: powerful curve analysis capabilities: freely select the cycles that need to be displayed, free combination of a variety of curves (such as voltage, current, capacity-time; capacity-voltage; number of cycles-voltage at the end of charge and discharge, , curve combination. It is open to customers to configure themselves.); Can move arbitrarily, zoom in and out the graph horizontally and vertically, view the details of the voltage, current, capacity, cell voltage and other data changes; select a single data file for comparison with different cycle data; optional Compare the curves of multiple data files.
• Function description
  • The hardware part of the equipment is of modular design, and each independent channel is one or more modules.
  • The equipment adopts the DC-DC conversion method, which is different from the traditional linear power supply method. The heat generated during the test is small, which not only avoids the safety and stability problems of the equipment test caused by the high temperature, but also saves the power consumption for the test.
  • Imported alloy material is used as the current sampling device, the full-load current output drift is small, which can effectively ensure the stability of large current testing and the reliability of full- scale long-term operation accuracy.
  • The current output of the equipment adopts the soft-start mode, which avoids the thermal shock of the battery and the connector caused by the instantaneous output of large current surge.
  • The equipment hardware control loop uses current and voltage dual-loop control, and the transition from constant current to constant voltage is smooth and without spikes.
• Basic process setting of equipment

Equipment Advantages

• High energy feedback efficiency: the efficiency is up to 75% when charging, and 65% when discharging. The heat generation is small, which reduces energy consumption and production heat;
• High channel output accuracy: Imported alloy material is used as the current sampling device, full load current output drift is small, 16-bit ADC/DAC unit is used, the accuracy is better than 0.05%, the sampling accuracy is high, and the long-term stability is good;
• Safety protection function: The equipment channel has multiple signal acquisition modules, which can monitor whether the voltage sampling line is off or abnormal, and whether thecurrent line is in good contact. When abnormal, the test will be suspended in time and the user will be reminded to ensure the safety of the test;
• Battery reverse connection protection function: When the battery is reversed, the hardware channel of the device is directly locked, and a red light will be lit when the output is disconnected to give a reminder to ensure the safety of the test;
• CCCV charging: During the charging process, CCCV has no gap transition, without any voltage and current impact. It can effectively prevent the battery from being concentrated due to the heat concentration of the peak current, which leads to the islanding effect or overshoot caused by the islanding effect or overshoot of the tab ears or micro-short circuit, which causes the protection action and secondary protection action of the PCB;
• Current start: soft start is used for the start of charging and discharging steps, and there is no current impact at the start moment;
