Battery Temperature Control Short Circuit Tester - China Suppliers & Factory for Safe and Reliable 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 safety features: Smoke exhaust, pressure relief, and emergency stop features address safety risks during high-temperature and short-circuit tests.
