Scope of Application
The basic functions of the battery comprehensive tester include: 1. Rapid detection of battery static parameters.
1.1 Battery voltage detection (for lithium batteries already in protection state, it can be automatically awakened). 1.2 Battery internal resistance detection. 1.3 Battery chargeability detection. 1.4 Battery dischargeability detection. 1.5 Battery overcurrent magnitude detection (only for lithium batteries). 1.6 Battery short-circuit protection function detection (only for lithium batteries). 1.7 Battery internal identification resistor 1 (or thermistor) detection. 1.8 Battery internal identification resistor 2 (or thermistor) detection. 1.9 For the above detectable values, upper and lower limits can be set respectively for rapid screening. 1.10 For batteries with communication chips, communication code testing can be performed (currently only for DS2502 compatible chips).
2. Battery capacity detection: Based on the selected battery type, number of series cells, and battery capacity, the most suitable voltage and current are automatically selected for a complete charge and discharge test. During the discharge process, the actual capacity of the battery is calculated, providing a strong reference for battery performance evaluation.
3. Selectable battery charging function: When this function is selected, the tester can be used as a multifunctional smart charger, capable of fast charging various types and combinations of rechargeable battery packs (up to 4 series lithium batteries, 12 series NiMH batteries, and 6 series maintenance-free batteries). This greatly facilitates battery usage and testing. During charging, the charging time and the amount of charge already delivered (displayed in mAH) are shown in real-time.
4. Selectable battery discharging function: When this function is selected, the battery comprehensive tester can discharge a single battery individually. The tester also controls the discharge cutoff voltage, avoiding the common issue of over-discharge with electronic loads or resistive loads. This is very convenient for factory testing of battery products. Operation is simple: just select the battery type, voltage, and capacity to start the intelligent discharge program, safely discharging the battery.
5. Numerically controlled current and voltage source function: When this function is selected, the instrument can be used as a precision numerically controlled DC power supply, with a maximum output of 10V and 2A. The output voltage and current limit can be set directly, making it convenient for special battery charging, testing, and powering other devices, expanding the instrument's applicability.
6. Numerically controlled electronic load function: When this function is selected, the instrument can be used as a precision electronic load, capable of operating in constant current, constant voltage, constant resistance, and constant power modes. In modes other than constant voltage, a cutoff voltage can also be set to facilitate battery discharge measurement, automatically cutting off the working current when the load voltage drops below the set cutoff voltage, preventing deep discharge damage to the battery. Additionally, the instrument can be used in other applications requiring an electronic load, such as charger testing and aging tests for switching power supplies.
7. Voltage and internal resistance meter function: When this function is selected, the instrument can be used as a general 3.5-digit digital voltmeter and digital milliohm meter, continuously displaying input voltage, battery internal resistance, and two additional ID resistance values. It can directly replace dedicated internal resistance meters for rapid battery screening and testing.
