Living Battery

A pack that explains itself, in words, instead of a percentage nobody trusts.

Research concept · QV-03

Pack reports independently of the vehicle, so it keeps its history through a change of owner.

Tap a part. Nothing here is a specification.

Current challenge

State of health is inferred rather than reported. Cell data stays inside the manufacturer's stack, so operators guess at residual value and plan around a number they cannot audit.

Research question

Can a battery continually and honestly explain its own health, age, charging habits and remaining useful life?

Open battery passport
On-pack diagnostics
Honest degradation forecast
Auditable residual value

Current blockers

Closed cell telemetry
No agreed health standard
Residual value incentives to stay vague

Potential breakthroughs

Open battery passports
On-pack diagnostics
Independent degradation modelling

What needs to change?

Engineering advances come from solving specific problems, not from wishful thinking.

Open cell telemetry

Health cannot be audited from the outside of a sealed pack.

A shared health definition

Two manufacturers' 90% are not the same 90%.

Charging habit history

How a pack was treated explains more than how old it is.

Engineering assessment

Judgements, not likes. Each scored one to five with the reason stated.

Impact

Honest residual value changes what a fleet can afford to buy.

Technical difficulty

The diagnostics exist. The openness does not.

Prototype readiness

A future authorised pilot could narrate battery passports from journey outcomes.

Environmental benefit

An auditable pack gets a second life instead of a shredder.

Scientific confidence

Degradation modelling is well understood; access is the barrier.

Fleet Memory connection

How today's One Fleet evidence could help answer tomorrow's engineering question.

Observed degradation across thousands of real charge sessions
Rapid-charge frequency against measured range loss
Temperature history correlated with energy use

Who might help

Battery companies
OEMs
Standards bodies
Leasing and residual value analysts

Back to today

Every One Fleet vehicle passport already narrates battery behaviour in plain English from journey outcomes.
