A no_std, zero-dependency library for estimating battery SOC from voltage
Documentation

Battery SOC Estimator

A no_std, zero-dependency library for estimating battery state of charge based on voltage. It includes temperature compensation and aging compensation features.

Features

  • ✅ Zero dependencies - No external crates required
  • ✅ no_std compatible - Perfect for embedded systems
  • ✅ No heap allocations - Fixed-size arrays only
  • ✅ Multiple battery types - LiPo, LiFePO4, Li-Ion
  • ✅ Temperature compensation - Basic temperature correction
  • ✅ Custom curves - Define your own voltage-SOC points

Installation

Quick Start

use battery_estimator::{BatteryChemistry, SocEstimator};
fn main() {
    // Create estimator for LiPo battery
    let estimator = SocEstimator::new(BatteryChemistry::LiPo);
    
    // Estimate SOC at 3.7V
    match estimator.estimate_soc(3.7) {
        Ok(soc) => println!("SOC: {:.1}%", soc),
        Err(e) => println!("Error: {}", e),
    }
}

Supported Battery Types

  • LiPo (4.2V - 3.2V)
  • LiFePO4 (3.65V - 3.0V)
  • Li-Ion (4.2V - 3.3V)
  • Lipo410Full340Cutoff (3.4V - 4.1V)
