Introduction

Mobile medical carts (workstations on wheels) require continuous power as nurses move from room to room. When these carts host high-performance edge AI hardware, power consumption increases significantly. Integrating hot-swappable batteries with the computer's internal power delivery system is crucial to prevent data loss and system reboots.

This article details how to interface hot-swap batteries with the TM-4433-10 Compact Medical Computer.

The Hardware Foundation: TM-4433-10 Compact Medical Computer

The TM-4433-10 Compact Medical Computer is a compact medical panel PC designed for mobile cart integration:

• Wide DC Input Range: Accepts variable voltage inputs typical of battery systems.
• 60601-1 Certified Isolation: Prevents electrical feedback from battery charging systems.
• Fanless & Compact: Fits easily on small cart mounts without restricting space.
• Intel Core Processor: Runs demanding clinical dashboard interfaces smoothly.

Step-by-Step Battery Interfacing

Step 1: Wiring and Ingress Protection

Connect the battery management system (BMS) to the PC's DC-in terminal using sealed, latching aviation connectors.

Step 2: Monitoring State of Charge (SoC) via SMBus / ACPI

We write a daemon script to poll battery health and capacity using standard Linux sysfs or Windows WMI interfaces.

import os

def read_battery_capacity():
    # Read capacity percentage from sysfs
    capacity_path = "/sys/class/power_supply/BAT0/capacity"
    if os.path.exists(capacity_path):
        with open(capacity_path, 'r') as f:
            return int(f.read().strip())
    return None

Step 3: Failsafe Actions

When the primary battery is removed, the system detects the transition to the secondary backup cell, alerting the user via on-screen notifications to insert a fresh battery.

Conclusion

Interfacing hot-swappable batteries with the TM-4433-10 Compact Medical Computer creates a reliable, continuous-run clinical workstation ready for edge AI tasks.
