IEC 60335-1:2021 Annex B Temperature Controlled External Short Circuit Tester

IEC 60335-1:2021 Annex B Temperature Controlled External Short Circuit Tester

Product Overview:

The Temperature Controlled External Short Circuit Tester is designed for lithium battery safety testing, battery cell abuse testing and external short-circuit testing.

With a maximum load current of 1000A, 20mΩ built-in resistor and ≤5μs DC response time, the system provides a controlled and repeatable high-current short-circuit test environment.

The integrated temperature-controlled chamber, battery surface temperature monitoring, automatic PLC control, smoke exhaust and explosion-proof protection make it suitable for battery R&D laboratories, safety testing laboratories and quality-control applications.

Applicable standards:

It is conforms to the standard of IEC 60335-1:2021 Annex B, UN38.3 clause 4.5 Test T.5, UL 1642, IEC 62619:2017 clause 7.2.1, IEC62133-1:2017 clause 7.3.2 , IEC62133-2:2017 clause 7.3.1 and 7.3.2 , IEC62133:2014 clause 7.3.2,8.3.1, 8.3.2, IEC60086-4 clause 6.5.1, IEC60086-4 clause 6.5.8 6.5.9 , and so on.

Key Features

• 1000A maximum load current for high-current battery short-circuit testing
• ≤5μs DC response time for rapid short-circuit response
• 20mΩ built-in resistor for controlled external short-circuit testing
• Temperature range: RT+10°C to 100°C
• 2-channel battery surface temperature monitoring, range -20 to 800°C
• PLC + touchscreen control for automatic test operation
• 0–1000A DC current acquisition with ±0.5% F.S. accuracy
• Integrated smoke exhaust, pressure relief and explosion-proof safety protection

Basic performance:

1. Simple operation and control: touch screen human-machine interface, touch editing control; the battery is placed on the shelf of the thermostat. Close the door and press the touch screen test button to automatically complete the test.
2. Safety and explosion-proof: The inner and outer boxes have been strengthened in design.
3. Overall aesthetic design: beautiful and elegant appearance.
4. Convenient to move into position: The bottom of the equipment is designed with universal wheels and leveling feet to facilitate the movement and fixation of the equipment.

Test requirements and steps:

1. After the equipment enters the laboratory, adjust the distance between the front, rear, left, and right of the equipment, adjust the leveling feet to make the base level, and fix the caster cups.
2. Connect the power cord to the device and test the machine. Only when there are no problems can you enter the product test.
3. Set the test parameters, place the battery on the shelf of the inner test box, close the door and start the test.
4. During the test, the door cannot be opened at will until the test is completed. After the observation time is over, the door can be opened to check the battery.
