Soft Battery Runtime Program

7.1 Drift Correction (Coulomb Counting)

Coulomb counting accumulates error over time (offset drift). The software must perform Full Detection Calibration:

• When the device is plugged in and voltage reaches 4.2V (and charge current drops to near zero), the software assumes 100% SoC and resets the capacity counter.

3. Hardware Requirements

To implement a soft battery runtime system, the following minimal hardware prerequisites are necessary: soft battery runtime program

1. Microcontroller (MCU): Must feature an ADC (10-bit minimum, 12-bit preferred) and low-power modes (sleep/standby).
2. Sense Resistor (Optional but recommended): A low-value, high-precision resistor (e.g., 0.1Ω, 1%) placed in series with the battery load for current measurement.
3. Voltage Divider: To step down the battery voltage (e.g., 4.2V Li-Ion) to the ADC's safe reference level (e.g., 3.3V or 1.2V).
4. Battery Datasheet: Essential for discharge curves and internal resistance specifications.

1. Introduction

The longevity of battery-powered electronics has traditionally been viewed as a hardware specification. Engineers select a battery with a specific Watt-hour (Wh) rating and design the hardware circuitry to operate within those limits. However, this static approach fails to account for the runtime variability of modern software. An application that processes heavy data streams for ten minutes consumes vastly different energy than one in sleep mode, yet the hardware often treats the battery as a static reservoir. Soft Battery Runtime Program 7

The Soft Battery Runtime Program represents a paradigm shift from hardware-only protection to software-defined energy management. An SBRP is a programmatic logic loop running within the device’s firmware or operating system that continuously monitors energy state, predicts future consumption, and actively modifies software behavior to meet energy targets. This paper explores the architecture, algorithms, and benefits of implementing soft battery management. When the device is plugged in and voltage reaches 4

Sample REST Payloads

• Set profile:

  POST /battery/profile

Part 5: How to Implement a Soft Battery Runtime Program (6 Steps)

Implementing a true SBRP requires engineering investment, but the ROI in user satisfaction and battery lifespan is immense.

Implementation Roadmap (quarterly)

• Q1: Core engine, REST API, CLI, basic Linux adapter.
• Q2: SDKs (Node, Python), Windows/macOS adapters, SSE/WebSocket events.
• Q3: Telemetry export, GUI, Android adapter.
• Q4: Advanced scenarios, security hardening, documentation and samples.

Runtime Behavior & Profiles

• Profiles:
  • Normal: nominal discharge rates, default capacity.
  • PowerSaver: slower drain, simulated background task limits.
  • Performance: faster drain due to higher CPU/GPU load factors.
  • Faulty: random drops, sudden voltage sag, rapid depletions.
  • Aging: reduced capacity and higher internal resistance over time.
• Events:
  • level_changed (with delta)
  • status_changed
  • critical_level (configurable threshold)
  • plugged_in / unplugged
  • thermal_alert
• Scheduling:
  • Support real-time and accelerated-time modes (e.g., 10x faster) for testing.
