Battery Temperature Control Short Circuit Tester - Top China Suppliers & Factory for Safety Testing Solutions
Equipment Structure
1. Control System
PLC touchscreen enables closed-loop temperature control with ±0.5℃ precision, optimized for consumer battery testing scenarios (e.g., simulating short circuits in smartphone batteries after high-temperature storage).
2. Heating System
Dual-zone ceramic heating wires, paired with horizontal forced air circulation via a high-speed fan wheel, ensure temperature uniformity within ±1℃. Built-in over-temperature protection and overload auto-shutdown safeguard both samples and equipment during long-term tests.
3. Short Circuit System
Industrial-grade high-current silver contactors support two resistor channels:
＜5mΩ low-resistance channel: Simulates sudden short circuits in compact consumer batteries (e.g., power bank internal shorts).
80mΩ resistor channel: Replicates abnormal low-current short scenarios (customizable for specific test protocols).
4. Auxiliary Functions
Visual explosion-proof glass window: Allows real-time observation of small-batch consumer battery tests while ensuring safety.
Integrated smoke exhaust, pressure relief, and emergency stop features: Address safety risks during high-temperature and short-circuit tests.
