The asset’s own baseline
Has relevant behaviour changed from what is normal for this charger under comparable conditions?
Sentinel maintenance intelligence
Investigate the change, not just the alarm.
Sentinel surfaces meaningful changes in charger evidence, explains why they deserve attention, and helps teams prioritise investigation across an estate.
Sentinel estate intelligence
Health
Understand what the available evidence says about operational condition.
State · change · trends
Observability
See the coverage, freshness and provenance behind the operational view.
Coverage · freshness · provenance
Evidence stays attached to findings, so teams can see what changed and why it matters.
Before certainty
You do not need a definitive diagnosis to justify a closer look
A single warning can be noise. A repeated warning, a shift from an asset’s own baseline, or a pattern across genuinely comparable chargers can be more useful.
The operational task is to decide what deserves attention and why. The maintenance view preserves that reasoning instead of hiding it behind an unexplained prediction.
Four evidence lenses
Look for change without overstating certainty
Repeated or correlated findings
Do warnings, state changes, measurements, and availability events form a recurring pattern?
Comparable fleet cohorts
Are similar changes visible across chargers with a genuinely comparable model, firmware, configuration, environment, and evidence profile?
Evidence degradation
Has telemetry become stale, intermittent, contradictory, or less complete? Reduced observability may itself justify checking the integration or asset.

Explainable findings
Why Sentinel surfaced this
Material findings keep the operational context and evidence needed to support investigation.
- Finding
- What changed or requires attention.
- Evaluated at
- When Sentinel evaluated the available evidence.
- Evidence freshness
- How recent the supporting inputs are.
- Supporting evidence
- The signals and events that support the finding.
- Conflicting evidence
- Inputs that weaken or challenge the conclusion.
- Missing or stale evidence
- Known gaps that affect confidence in the view.
- Source and integration path
- Where the evidence originated and how it reached Sentinel.
- Applicable scope
- The relevant model, firmware, configuration and operating context.
- What remains uncertain
- The questions the available evidence cannot answer.
- Suggested investigation
- A clear operational next step for the team.
Cohort intelligence
Compare chargers on relevant evidence
Sentinel groups assets only where model, firmware, configuration, operating context and evidence coverage make the comparison meaningful. The cohort context stays visible alongside each finding.
Operational judgement
Prioritisation with the evidence attached
A surfaced pattern is a reason to investigate. Teams retain the supporting, conflicting and missing evidence needed to apply qualified judgement and follow the appropriate maintenance process.
FAQ
Maintenance questions
Does Sentinel predict charger failures?
Sentinel surfaces evidence and patterns that may justify earlier investigation. It does not guarantee that every failure will be predicted or diagnosed.
What can make a charger stand out?
A change from its own baseline, repeated findings, comparable cohort trends or deteriorating telemetry can move a charger up the investigation list.
Is a Sentinel finding a safety instruction?
No. It is an operational monitoring finding. Device-local protection and qualified maintenance procedures remain separate.
Can chargers from different manufacturers be compared?
Only where the relevant context and evidence are meaningfully comparable. The system should show limitations rather than force unlike assets into the same benchmark.
