Background

In early 2024, a renowned U.S.-based manufacturer, founded in 1982 and headquartered in Eagan, Minnesota, approached PKNERGY with a specialized requirement: to develop a backup battery solution for a hospital-grade mobile workstation. Known for its high standards across medical, office, and industrial sectors, the client emphasized absolute safety, stability, and rapid delivery.

Parameter information: The battery pack adopts 4S1P design, and the maximum input/output power reaches 100W.

The Challenge

Designing this backup power system came with unique constraints:

• 🛠️ Fixed structure: The mobile workstation was already in final production, limiting modification space.

• 🔌 Two-in-one wiring: Required output and communication lines to share one cable.

• 🔄 Port integration: Input and output ports had to be unified.

• ⏱️ Tight timeline: The client demanded a 3-week turnaround, from concept to sample delivery.

• 📐 Zero-error engineering: Their engineering team maintained strict validation protocols, leaving no margin for error.
