Overview
The temperature-controlled battery short-circuit testing machine (model: ASR-9010) is a professional equipment designed to integrate the requirements of various battery short-circuit testing standards. It adopts PLC automatic control to simulate the external short circuit of the battery, and can record the change of battery voltage, current and surface temperature. The equipment uses industrial-grade DC electromagnetic contactor, all-copper terminal and internal copper plate to conduct current to ensure that the internal resistance of the circuit is less than 5mΩ, and can withstand short-circuit current with a peak value of 1000A, which effectively improves the heat dissipation effect and safety, and ensures the accuracy of the test data.
Features
1. Adopt PLC touch screen control system, easy to operate, and equipped with a remote control.
2. The key components are industrial-grade DC electromagnetic contactors, all-copper terminals and internal copper plate conductors, with low internal resistance (≤ 5mΩ) and good heat dissipation performance.
3. Short circuit device design can withstand the high current impact of peak 1000A, safe and reliable.
4. With temperature control function, Temperature range of temperature control box is normal temperature~ 150 ℃, control accuracy of 0.1 ℃.
5. Two short circuit stop modes are available: stop according to the set short circuit time or stop according to the battery surface temperature conditions.
6. Equipment is equipped with windows (300 * 300mm tempered explosion-proof Glass), exhaust fans and supplementary trends, easy to observe and ventilate.
Principle
The testing machine automatically performs the short-circuit test through the PLC control system. The battery that is fully charged and reaches the specified environment temperature (such as 55 ° C +/- 5 ° C) is connected to its positive and negative extremes with wires, so that the entire external circuit resistance is controlled at 80 +/- 20mΩ. The DC electromagnetic contactor inside the device is sucked in to form a short-circuit circuit, simulating the external short-circuit state of the battery. At the same time, the device continuously monitors and records the change of the voltage, current and surface temperature of the battery, and automatically terminates the test when a preset stop condition is reached (such as short-circuit time or battery temperature).

Standards
GB 31241-2014、MT/T 1051-2007、SJ/T 11169-1998（UL1642：1995）、YD 1268-2003、GB/T 19521.11-2005、GB/T 18287-2013、SJ/T 11170-1998 （UL2054：1997）、UN 38.3、UL 1642、UL 2054、IEC62133-2012、GB/T 8897.4-2008（IEC 60086-4：2007）、YDB 032—2009、YD/T 2344.1—2011、GB/T 21966-2008（IEC 62281：2004）
Steps
1. Fully charge the battery according to the method specified in the relevant standards.
2. Place the battery in the temperature control box of the testing machine and set the environment temperature to 55 ° C +/- 5 ° C.
After the battery temperature stabilizes to 55 ° C +/- 5 ° C, hold it for another 30 minutes.
4. Connect the anode and cathode terminals of the battery with wires to ensure that the entire external circuit resistance is 80mΩ +/- 20mΩ.
5. Set test stop conditions (such as short circuit time or battery surface temperature threshold) in the PLC control system.
6. Start the short-circuit test, and the equipment automatically pulls in the contactor to start the test.
7. During the test, the device automatically monitors and records the battery voltage, current and surface temperature.
8. When preset stop conditions are met (e.g. battery temperature drops by 20% from peak, short circuit time reaches 24 hours, etc.), the test is automatically terminated.
Notice
* Before the test, make sure that the battery has been fully charged according to the standard requirements and reaches the specified environment temperature conditions.
When connecting the battery, make sure that the wires are firmly connected and the entire external circuit resistance meets the requirements of 80 +/- 20mΩ.
When the equipment is running, do not open the box door or touch high-temperature parts to prevent burns or accidents.
Please check regularly whether the electrical connection parts of the equipment (e.g. contactors, terminals) are tight and show no signs of overheating or damage.
* The exhaust pipe at the back of the equipment should be kept unobstructed, and the left side should not be blocked to ensure ventilated heat dissipation and measurement needs.
When conducting tests, the parameters recorded by the equipment should be closely observed, and attention should be paid to whether the battery shows any abnormalities (such as fire or explosion). The maximum temperature should not exceed 150 degrees Celsius.
* The weight of the equipment is about 100Kg, and attention should be paid to safety when moving and installing to prevent dumping.
Please use the specified AC220V, 50/60Hz power supply to power the device.
