Technical details and manufacturing context for Power Supply (Battery)

Definition
The power supply (battery) is a critical component within a transmitter/sonde system, responsible for converting stored chemical energy into stable, usable electrical power to drive the device's sensing, processing, and signal transmission circuits. It ensures autonomous operation in remote or mobile applications.
Working Principle
The battery operates on electrochemical principles, where a chemical reaction between electrodes and electrolyte generates a flow of electrons (current) at a specific voltage. This DC power is then regulated and supplied to the transmitter/sonde's internal circuitry to maintain consistent operation until the battery's energy is depleted.
Common Materials
Lithium-ion compound, Metal casing, Electrolyte, Separator
Technical Parameters
  • Nominal voltage (e.g., 3.7V) and capacity (e.g., 2000mAh) defining the energy output and runtime. (V, Ah) Customizable
Components / BOM
  • Cathode
    Positive electrode where reduction occurs during discharge.
    Material: Lithium cobalt oxide (LiCoO2) or similar
  • Anode
    Negative electrode where oxidation occurs during discharge.
    Material: Graphite
  • Electrolyte
    Medium that allows ion movement between electrodes.
    Material: Lithium salt in organic solvent
  • Separator
    Prevents physical contact between anode and cathode while allowing ion flow.
    Material: Polyethylene/polypropylene film
Engineering Reasoning
2.7-4.2 VDC per cell (lithium-ion), 1.8-2.2 VDC per cell (lead-acid)
Cell voltage below 2.5 VDC (lithium-ion irreversible damage), below 1.75 VDC (lead-acid sulfation)
Design Rationale: Electrochemical degradation: lithium-ion experiences copper dissolution at anode below 2.5 VDC; lead-acid forms irreversible lead sulfate crystals below 1.75 VDC
Risk Mitigation (FMEA)
Trigger Internal short circuit from dendrite growth exceeding 10 μm penetration
Mode: Thermal runaway initiating at 80°C with 10°C/min heating rate
Strategy: Ceramic-coated separator with 150°C melt integrity and pressure-sensitive current interrupt device
Trigger Electrolyte decomposition at 4.3 VDC overcharge voltage
Mode: Gas generation exceeding 10 kPa internal pressure causing casing rupture
Strategy: Voltage monitoring IC with 4.25 VDC cutoff and redundant pressure relief valve at 15 kPa

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Sulfation
Cause: Lead-acid battery plates become coated with lead sulfate crystals due to prolonged undercharging or storage at low state of charge, reducing capacity and increasing internal resistance.
Thermal runaway
Cause: Excessive charging current or high ambient temperatures cause internal heat generation to exceed dissipation, leading to uncontrolled temperature rise, electrolyte boiling, and potential battery rupture.
Maintenance Indicators
  • Visible bulging or deformation of battery casing indicating internal pressure buildup
  • Audible hissing or gurgling sounds from vent caps during normal operation suggesting electrolyte boiling
Engineering Tips
  • Implement temperature-compensated charging: Adjust charging voltage based on battery temperature (typically -3 to -5 mV/°C/cell) to prevent overcharging in hot conditions and undercharging in cold conditions.
  • Maintain optimal state of charge: Keep batteries between 50-80% state of charge during storage, perform equalization charges periodically, and avoid deep discharges below 20% capacity to prevent sulfation.

Compliance & Manufacturing Standards
