Voltage
Measure electrical potential across the monitored circuit.
SO-EMS M01
Energy Meter
M01 is the first physical measurement module of the Sustainable Oasis Energy Management System.
Its purpose is to create a trusted low-voltage DC measurement bench capable of tracking voltage, current, power and accumulated energy through a defined system.

M01 PURPOSE
Build the measurement layer before judging the experiment.
A Sustainable Oasis energy experiment should not rely only on voltage, current or visible motion.
M01 is designed to accumulate energy over time so that input and output can be compared using watt-hours.
CORE MEASUREMENTS
Four values create the foundation.
Current
Measure electrical current flowing through the monitored path.
Power
Calculate instantaneous electrical power from voltage and current.
Energy
Accumulate power over time to determine the energy transferred through the measurement point.
ELECTRICAL MODEL
Power is a rate. Energy includes time.
V × A
W
W × TIME
Wh
Because voltage and current can change during a test, M01 should accumulate measurements over time rather than assume one constant power value.
BENCH ARCHITECTURE
A simple physical path with visible measurement points.

OUTPUT METER
LOAD
DC Source
A defined low-voltage battery or regulated DC power source supplies the experiment.
Protection
Use appropriately rated protection such as a fuse or current-limited power supply.
Device Under Test
The motor, converter, generator, controller, load or experimental subsystem being evaluated.
Known Load
A defined load helps create repeatable test conditions.
M01 MEASUREMENT POINTS
Measure both sides of the experiment.
Source Input
Record voltage, current, power and watt-hours entering the experimental system.
INPUTDevice Output
Record electrical output leaving the device under test.
OUTPUTStorage Input
Record energy entering a battery or other electrical storage device.
STORAGE INStorage Output
Record energy leaving storage during discharge.
STORAGE OUTRecovery Path
Measure recovered electrical energy separately from primary source energy.
RECOVERYSYSTEM BOUNDARY RULE
If energy enters the experiment, count it.
External chargers, auxiliary batteries, powered controllers, reset mechanisms and storage depletion can all contribute energy to a test.
M01 is useful only when the system boundary is defined clearly enough that important energy inputs cannot hide outside the measurement.
STANDARD TEST PROCEDURE
Use the same sequence every time.
Define the Question
Write exactly what the energy test is intended to determine.
Define the Boundary
Identify what is inside the system and which energy sources must be counted.
Record Starting State
Record source voltage, battery state and relevant initial conditions.
Zero the Meters
Reset accumulated energy values before the test begins.
Start the Test
Begin the experiment under documented operating conditions.
Log Measurements
Record voltage, current, power, energy and timestamps.
Stop at Defined Condition
Use a predetermined duration, energy level or system condition to end the test.
Record Final State
Measure remaining storage and other relevant ending conditions.
Compare Energy
Compare total measured inputs, outputs, storage change and recovered energy.
Repeat
Repeat the experiment before treating one result as reliable.
M01 DATA RECORD
Minimum dataset for every energy run.
Test ID
Assign a unique reference to every test run.
Timestamp
Record start, stop and measurement interval.
Input Voltage
Record source voltage during operation.
Input Current
Record source current during operation.
Input Power
Track instantaneous power entering the system.
Input Energy
Accumulate total watt-hours supplied during the run.
Output Energy
Accumulate useful electrical output in watt-hours.
Recovered Energy
Record recovered energy on its own measurement path.
CALCULATED METRICS
Derive metrics only after the raw measurements exist.
Conversion Efficiency
Useful output energy divided by measured input energy, expressed as a percentage for the defined boundary.
Efficiency = Wh Out ÷ Wh In × 100
Recovery Fraction
Recovered energy compared with the relevant measured input or process energy.
Recovery = Wh Recovered ÷ Reference Wh × 100
Accounted Loss
Energy entering the boundary that is not found in useful output or increased storage.
Loss = Wh In − Wh Out − ΔWh Storage

METER VALIDATION
Test the meter before testing the experiment.
Voltage Check
Compare the M01 voltage reading with a trusted reference meter.
Current Check
Compare current measurement at several known load levels.
Known Load Test
Operate a stable load for a known duration and compare expected energy with accumulated watt-hours.
Repeatability
Repeat the same test to verify that results remain reasonably consistent.
Record Error
Document observed meter error instead of assuming perfect measurement.
M01 → CONTROL ROOM
The long-term goal is automatic measured data.
Today, Sustainable Oasis Online can store manual, demonstration and estimated values.
M01 gives us the physical measurement layer needed to begin replacing those values with instrumented energy data.
Each incoming value should eventually carry its source, timestamp and MEASURED classification.

M01 SAFETY
Begin with controlled low-voltage DC testing.
M01 is intended to establish measurement methods at low voltage and limited energy before moving toward larger systems.
Batteries can still deliver very high fault current. Conductors, connectors, fuses, switches and meters must be appropriately rated for the test circuit.
High-voltage, mains-connected and high-energy systems require suitable equipment, protection and qualified expertise.
