🔧 Battery Pack Busbar Welding: Laser vs. Ultrasonic vs. Resistance

Busbar welding may look like a small manufacturing detail, but it can have a major impact on battery pack performance and safety.

A poor weld can increase resistance and create localized heating under high current.

So which method should manufacturers choose?

⚡ What really happens inside a BESS PCS during a grid fault?

Fault Ride-Through (FRT) is much more than a voltage-against-time curve on a datasheet.

A PCS must simultaneously protect its semiconductor devices, control fault current, manage DC-link voltage, and support the grid.

Key technologies include:

🔋 DC-link choppers and dump…Read More
