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 parts where the value can be detected, 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, the number of batteries in series, and the battery capacity, the most suitable voltage and current are automatically selected to perform 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: By selecting this function, the tester can be used as a multifunctional smart charger, capable of fast charging various types of rechargeable battery packs in various combinations (up to 4 series lithium batteries, 12 series nickel-metal hydride batteries, and 6 series maintenance-free batteries), greatly facilitating battery use and testing. While charging, it displays the charging time and the amount of charge already input (in mAH) in real time.
4. Selectable battery discharge function: By selecting this function, the battery comprehensive tester can discharge a single battery individually. The grand battery tester also controls the discharge cut-off voltage, avoiding the disadvantage of easy over-discharge commonly seen with electronic loads or resistor discharge. It is very convenient for factory testing of battery products, and operation is also simple: just select the battery type, voltage, and capacity to start the intelligent discharge program and safely discharge the battery.
5. Numerically controlled current and voltage source function: By selecting this function, the instrument can be used as a precision numerically controlled DC power supply, with a maximum output of 10V and a maximum output of 2A DC. The output voltage and current limit can be directly set, making it convenient for special battery charging, testing, and powering other devices, expanding the instrument's scope of application.
6. Numerically controlled electronic load function: By selecting this function, 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 cut-off voltage can also be set to facilitate battery discharge measurement, allowing the load to automatically cut off the working current when the voltage falls below the set cut-off voltage, preventing deep discharge damage to the battery. In addition, the instrument can be used in other applications requiring electronic loads, such as charger testing and aging tests for switching power supplies.
7. Voltage and internal resistance meter function: By selecting this function, the instrument can be used as an ordinary 3.5-digit digital voltmeter and digital milliohm meter, continuously indicating the input voltage, battery internal resistance, and the two additional ID resistance values. It can directly replace a dedicated internal resistance meter for rapid battery screening and detection.
