Battery test:
In electric vehicle battery management system (BMS), resistance technology is used for insulation resistance detection to ensure the safety and stability of the battery. GB/T 38661-2020 standard puts forward clear technical requirements for the insulation resistance detection function of BMS, including accuracy requirements, test methods and test conditions.
Platinum resistance temperature sensors play an important role in the battery management system of new energy vehicles, which is used to monitor the temperature of the battery pack to ensure the safety and efficiency of the battery charging and discharging process.
Wire-wound resistors and thick film resistors are widely used in pre-charge, balancing, filtering and other scenarios in the field of new energy.
Resistance welded pipe technology by heating the welded joint, so that the two pipes in a high temperature state to achieve the connection, welding speed, high efficiency, good welding quality, so it is widely used in solar energy, wind energy and other new energy equipment manufacturing field.
Solar cell Application:
The application of impedance spectrum measurement technology in solar cell fault detection and electronic transport has been deeply studied. Impedance spectrum information includes not only DC resistance information, but also dynamic capacitance, inductance and other information, which is helpful to improve the performance evaluation and fault diagnosis ability of solar cells.
The application of new Ni-Ruthenium nanoelectrodes in quantum dot solar cells, based on the hydrothermal method of low-cost, low-energy electrode preparation and performance evaluation, the electrical properties of the electrode were studied in detail. Electrochemical impedance spectroscopy (EIS) test has become one of the important research methods in the field of solar cells.
The TLM (Transmission Line Matrix) contact resistance tester optimizes the measurement result of the contact resistivity by adjusting the geometry, and improves the measurement accuracy of the contact resistivity of silicon solar cells.
SWCT uses fine grid lines and dense matrix connections to not only reduce resistance losses but also reduce the covered area of the solar cell surface, effectively increasing the power of the module.
