Do you really understand the comprehensive battery tester?
Commonly known rechargeable batteries include lithium batteries, NiCd batteries, NiMH batteries, and sealed lead-acid batteries. For these rechargeable battery production testing needs, a special rechargeable battery comprehensive tester, the tester can do a quantitative and accurate measurement of some basic parameters of the battery, can measure the battery open circuit voltage, internal resistance, charging, discharging performance, battery capacity, especially for the lithium battery function and overcharge protection, over discharge protection, over current protection, short circuit protection and other functions, and measured over Corresponding values, greatly facilitate the production of batteries and pre-sales and after-sales service work, using a very simple few steps can intuitively determine the performance of the battery and good or bad, but also has a fast screening function, you can set the upper and lower limits of the measurement parameters, you can easily detect bad batteries from a batch of finished batteries quickly, improving production efficiency. In addition, some special functions are also attached to make it have some characteristics of general instrumentation, expanding the flexibility of the use of equipment, as well as having a wide range of features.
The basic functions of the comprehensive battery tester include.
1. Rapid detection of battery static parameters
1.1 Battery voltage detection (for the lithium battery already in the protection state, can automatically wake up)
1.2 Battery internal resistance detection
1.3 Battery rechargeable performance detection
1.4 Battery dischargeable performance detection
1.5 Battery overcurrent size detection (only for lithium batteries)
1.6 Battery short circuit protection function detection (only for lithium battery)
1.7 battery internal identification resistance 1 (or thermistor) detection
1.8 Battery internal identification resistor 2 (or thermistor) detection
1.9 The above detectable values can be set separately for upper and lower limits for quick screening.
1.10 Communication code test can be performed for the battery of communication code piece (currently only for DS2502 compatible code piece)
2. Battery capacity test
For the selected battery type and the number of batteries in series as well as the battery capacity, the most suitable voltage and current are automatically selected for a complete charging and discharging test, and the real capacity of the battery is calculated during the discharging process to provide a strong reference basis for the battery performance discrimination.
3. Individually selectable battery charging function
select this function, the tester can be used as a multi-functional intelligent charger, for various types of various combinations of rechargeable battery charging (up to 4 lithium batteries in series, 12 series of NiMH batteries, 6 series of maintenance-free batteries for rapid charging), greatly facilitating the use of batteries and the convenience of testing, in the charging at the same time, real-time Display the charging time, as well as the amount of power has been charged (displayed in mAH).
4. Individually selectable battery discharge function
select this function, the tester can discharge a battery alone, while controlling the discharge cut-off voltage, avoiding the usual electronic load or resistance discharge brought about by the disadvantages of easy over-discharge, very convenient for factory testing of battery products, the operation is also very convenient, only need to select the battery type, voltage and capacity to start the intelligent discharge program, safe discharge operation of the battery. Safe discharge operation of the battery.
5. CNC current and voltage source function
select this function, the tester can be used as a precision CNC DC power supply, the maximum output 10V, the maximum output 2A DC power supply, you can directly set the output voltage and limit the current, can be easily used in the battery special charging, testing, and power supply to other devices, expanding the scope of application of the instrument.
6. CNC electronic load function
select this function, the tester can be used as a precision electronic load, can be set to work in constant current, constant voltage, constant resistance, and constant power mode of operation, in addition to the constant voltage mode of operation, you can also set the cut-off voltage (cut off), to facilitate the battery discharge measurement, you can make the load voltage below the set cut-off voltage, automatically cut off the work When the load voltage is lower than the set cut-off voltage, the current will be cut off automatically to avoid the damage to the battery by deep discharge. In addition, the instrument can also be used for other occasions that require electronic loads, such as charger testing, switching power supply aging test, etc.
7. Voltage and internal resistance meter function
Select this function, the tester can be used as a common 3.5 digit voltmeter and digital milliohm meter, which can continuously indicate the input voltage and internal resistance of the battery, as well as the additional two ID resistance values, which can be used directly instead of the special internal resistance meter for fast battery screening and testing.
8. Calibration
Select this function, the tester can be opened without the case, the instrument for calibration processing, in order to maintain a high measurement accuracy at any time, can be calibrated items include, voltage measurement, internal resistance measurement, charging current measurement, discharge current measurement, etc., this function requires the input of calibration password, to avoid the misuse of unrelated personnel.
9.Read code function (currently only for DS2502 compatible code slice, applicable to all MOTO cell phone batteries):
Select this function to read out all the internal data of DS2502 compatible code slice, but real-time observation of the data of any address, and see the last CRC check data, by comparing the last two bytes of CRC check data, you can determine whether the transmission data is wrong.
Battery comprehensive tester is a general name, according to the form of the battery and battery assembly after the classification of the finished product, the tester can be divided into: battery cell tester, finished battery comprehensive tester, cell phone battery tester, laptop battery tester, mobile DVD battery tester, battery tester, all can do comprehensive performance testing. New products can be connected to a computer, you can set parameters through the computer, and can save, print test data, record capacity test results data, and draw capacity test curve and other functions.
