BESS Engineering

BESS SoC Optimization & Energy Throughput

Usable energy from nameplate and DoD window. Daily and annual energy throughput. Lifetime vs warranty limit. Optimal SoC window per chemistry.

Presets

Battery & Usage Parameters

Cell Chemistry

Nameplate Capacity

kWh

Rated energy capacity at new condition (100% SoC)

Minimum SoC Limit

10 %

DoD upper bound — prevents over-discharge

Maximum SoC Limit

90 %

Prevents over-charge; grid-scale often capped at 90%

Charge Power

Grid charging power

Discharge Power

Load supply power

Daily Cycle Duration

h/day

Hours per day at charge/discharge rate

Round-Trip Efficiency

RTE applies to net throughput (charge + discharge averaged)

Self-Discharge Rate

%/day

Chemistry default pre-filled; LFP 0.05%, NMC/NCA 0.1%, LTO 0.02%

Warranty Throughput Limit (optional)

MWh

Leave blank to use chemistry default (e.g. LFP ~6000 MWh)

Project Life

years

Typical BESS project life: 10–25 years
