High current probe are divided into many types. According to current, there are 30A , 50A, 150A current probe. The maximum current through from the high current probe is mainly determined by the cross-sectional area of the probe. The larger the cross section area, the greater the current can pass. This paper introduces the 150A high current probe, which is used in the power car's lithium battery charge and discharge test.

1.The characteristics of the product

For common high current probe, there is only a needle in the body. For 150A high current probe, there are two needles inside. This design can be transmitted separately current and voltage, form a four-wire transmission. Another purpose of two needles designed is to avoid breaking. Ordinary high current needle can not be reused once one needle is damaged. While the large current pin 150A has two needles. One damaged, the other one can continue to use. So two needle design is more reliable and practical. 150A large current pin is also very intelligence. When contact, the surface can be automatically adjusted to make the contact more effective. The large current probe unit is customized to accommodate the different test environments and the head shape can be changed.
