[Free Support] Resolving measurement issues in battery charge and discharge testing.
The charge and discharge tests involve prolonged current flow compared to regular electrical measurements, so controlling the heat generation at the contacts affects the stability of the measurements.
Do you have concerns such as, "The contact resistance is inconsistent, and I'm worried if charging and discharging are working," "The power supply is unstable, and the test stops midway," or "The workpiece and probe are sticking together and adhering"? Charging and discharging tests involve longer durations and higher currents than regular measurements, making it more likely for issues caused by heat generation to arise, such as: 【Problems due to heat generation across the entire line】 - Decreased load due to spring fatigue, etc. 【Problems due to heat generation at the contact points】 - Promotion of shape changes at the probe tip - Promotion of foreign object adhesion, etc. These issues can become more pronounced if the probe is not suitable for the workpiece shape or measurement conditions. Therefore, we will take your workpiece and the probes currently in use, and conduct experiments on contact resistance and other factors using our own equipment. We will visualize "why the measurements are not going well" with data and identify the root causes of measurement failures. Based on this, we will propose the optimal probe shape and load conditions suited to your usage conditions and workpiece characteristics, providing free support all the way to the selection that leads to actual improvements. Please feel free to contact us through the inquiry form.

Contact probes are indispensable for the manufacturing of all precision instruments. Since entering this field 50 years ago, Sankei Engineering has actively worked on "technologies and products that cannot be imitated by other companies," accumulating unique know-how. Particularly in specialized areas that require high precision, such as measurements under high current, high voltage, and extreme temperatures, it is difficult to meet the demands without our outer spring type (integrated) contact probes, establishing a significant competitive advantage in this market.
