1. Equipment Features
- The constant voltage and constant voltage charging is safe and smooth, and the voltage and current sampling output of the device is controlled through the four-wire system connection for soft start, so as to make a safe and smooth transition in the constant voltage and constant voltage charging process to avoid the occurrence of peak damage to the battery.
- High-precision calibration: charging current, discharge current, charging voltage and discharge voltage are all calibrated by Agilent with high precision to ensure the accuracy of current and voltage within 0.5‰;
- Segmental range design, in the operation of the equipment, according to the different output value of the internal intelligent adjustment of the range of the equipment, to ensure the high precision of each stage;
- Excellent thermal performance, unique duct design, through forced air cooling to reduce the impact of high temperature on equipment performance. The dual fan mode is adopted to carry out forced ventilation and cooling for the power cooling module, and the thermal imager is used for thermal simulation test to ensure that the cooling device works within a reasonable temperature range.
- Channels can be detachable, can be customized according to the needs of each channel in the same box in free parallel, to be compatible with a variety of types of battery test, give full play to the same type of multi-purpose equipment, save equipment costs for customers;
- The device has built-in temperature. Each channel can be customized with one main temperature without external auxiliary temperature (with multiple channels, external auxiliary temperature is required). The battery temperature is monitored in real time to monitor and protect the normal safety test of the battery according to the temperature change.
- Single box power supply, each box of the whole cabinet independent power supply, to ensure the stability and safety of the whole cabinet power supply;
- The power supply is independent to ensure that the circuit output is even in the process of power supply operation and there is no protection problem;
- The fixture is flexible and adjustable, and it can be compatible with multiple types of batteries, so as to truly achieve a multi-purpose and maximize the use value.
