We heard a lot of complains about how to test the high current on IGBT components or Battery cells

As the great development of  E-cars like Tesla, BYD, MI, NEO and etc, now the high power or current battery cells are moving so faster than ever before, 

Today, a majority of companies that specialize in battery cell manufacturing equipment are in China, Japan, and South Korea. However, many Asian battery cell manufacturing suppliers are operating at more than 95 percent capacity.

The surge in demand for EVs is on pace to outstrip supply of battery cells in the coming years, based on the announced build-out capacity to date. A base-case 

EV uptake scenario requires more than 3,900 GWh of battery capacity globally by 2030 with passenger cars accounting for roughly 2,400 GWh, while an aggressive

uptake scenario requires an additional 600 GWh. Geographically, the need varies; battery cell demand will remain highest in China, followed by Europe and the United States.

That said, additional cell capacity estimates based on the announcements of battery cell manufacturers sum to a global supply of approximately 2,900 GWh by 2030 (exhibit). 

Overall, 60 new gigafactories6 with an average production capacity of 25 GWh are being planned for construction globally by 2030. There is a tendency for gigafactories to

 become larger on average, in some cases reaching up to 100 GWh.

So the Li-battery cells are unlocking growing on the big capacities and abilities, high over 500amp current in demand is very common in an E-vehicle.

Our testing factories are meeting these challenges on how to test them in a safety way.

We JYPROBE recommend a high-current test probe solution for battery cells on high-current and high-voltage.

For an example 120amp current probe.
