Low-Power Design Services for Battery-Powered Devices
Design Smarter, Run Longer: Engineering for Battery Life
Battery life isn’t just a spec — it’s a product enabler. From smart sensors and asset trackers to medical wearables and wireless controllers, extended runtime is critical to usability, safety, and maintenance cost.
At Promwad, we deliver low-power hardware and firmware design services that make electronics last longer in the field. Whether you're building a 10-year node on a coin cell or optimising a connected device with peak-load bursts, our engineers help you push boundaries without trade-offs on performance or functionality.
What We Offer
Firmware & Software Customisation
- RTOS-based or bare-metal low-power firmware design
- Sleep modes, wake-up sources, and interrupt-driven logic
- Smart scheduling and batch processing to reduce active time
- Firmware profiling and runtime diagnostics (tickless timers, watchdogs)
Battery & Energy Management Strategy
- Coin cell, LiPo, Li-SOCl2, supercap, and hybrid support
- Fuel gauge, coulomb counting, and state-of-charge algorithms
- Energy harvesting (solar, kinetic, RF) integration planning
System-Level Profiling & Validation
- Power profiling using special equipment for optimisation
- Peak current measurement, duty cycle tuning, thermal impact analysis
- Long-duration logging and scenario-based energy modelling
- Validation against real-world usage profiles (indoor/outdoor, motion, idle)
