BATTERY LIFECYCLE INTELLIGENCE
See how much life
your batteries have left.
A battery management platform built on a physics-informed AI life prediction model.One continuous data record from deployment (BOL) through operation (MOL) to end of life (EOL).

Every battery faces a decision after service
When service ends, each battery has to be cleared for reuse or sent to recycling.That call is only as good as the operating record behind it.Most sites either don't keep that record or lose it between stages.
Issue 01
Broken operating records
Operating data disappears when a battery leaves the site.Its history never reaches the people making the call.
Issue 02
One-time testing
Years of degradation and remaining life are inferred from a single final measurement.
Issue 03
Reusable batteries lost
Without evidence, decisions default to the safe side.Batteries that could be reused get shredded instead.
Our approach: capture data where batteries operate, and carry the same record all the way to the final decision.
Different questions at every stage. One data record.
Designed around reused batteries.Handles mixed makers and specs, incomplete histories, and uneven aging.Works just as well for new batteries.
BOLDeployment
Is it fit for ESS?
Go/no-go based on predicted remaining life · Expected service life and economics
MOLOperation
Is it healthy right now?
Continuous operating logs · Early anomaly alerts · State-aware charge and discharge control
Physics × AI
Battery life prediction model
An ensemble of electrochemical modeling and deep learning.Physics rules out impossible answers. Deep learning picks up subtle degradation patterns.Reliable even when a battery's history is incomplete.
Inference —
01 · Sense
Signal input
Cell-level voltage, current, temperature, and SOC time series.Operating history included.
02 · Reason
Parallel inference, fused
Electrochemical model and Kalman filter alongside CNN, LSTM, and attention, combined in a physics-informed ensemble.
03 · Learn
Field retraining
Retrained on live data from JDMS and JD EMS.Accuracy improves with every new deployment.

Who uses what
Point solutions vs. one connected lifecycle
A separate tool for each stage
Built-in BMS diagnostics · ESS EMS · ITAD software
- Batteries are retested every time they change hands
- Reusable batteries are lost for lack of evidence
- A separate contract and integration for every vendor
Joodra, end to end
JD Plan · JDMS · JD EMS · JD Works
- Decisions based on operating data, with no retesting
- More batteries recovered for reuse
- One contract covers every stage
