Battery Cycle Life Test 120V 1000A Battery Pack Testing Equipment
Equipment Overview
1. This equipment adopts power feedback technology, which has high energy saving efficiency and small heat generated by the system, which can greatly reduce the heat emission, power consumption and usage cost of the equipment.
2. Three-phase balancing technology (no neutral line) to reduce grid load;
3. Soft start function at startup to reduce the impact on the power grid;
4. The equipment accuracy is better than 0.05%, the data recording time can reach 1000mS/time, and the stability is high;
5. Single point independent, independent charging and discharging conditions can be set for each channel;
6. It has complete input and output, software and hardware protection, reverse connection protection, power-off and reconnection protection, fixture poor contact protection and other functions;
7. There is no inrush current when the channel is started, and there is a seamless transition from constant current to constant voltage without any current surge;
8. Multi-layer network integrated management, one computer can provide centralized control of 1000+ channels, and large systems support remote monitoring;
9. The DC internal resistance test process can be customized and set up to provide a high-reliability basis for cell assembly (optional);
10. Channels can be freely connected in parallel as needed to achieve multiple uses in one machine;
11. When the computer is abnormal, it supports offline operation at an appropriate time (optional);
12. Modular design concept, plug-in box design, easy to maintain;
13. The output line adopts quick-plug method to facilitate installation and maintenance;
14. The battery end uses a gold-plated thimble clamp to press down to reduce heat generation and facilitate battery loading and unloading;
