For EV drivers, this is frustrating. For charge point operators (CPOs), repeated incidents can affect customer experience, network reliability and revenue.
This is why EV charger uptime is an important measure of charging network performance.
What does EV charger uptime mean?
Uptime refers to the amount of time a charger is available and functioning as expected.
It is often expressed as a percentage over a specific period.
For example, if a charger is operational for 95 hours out of a 100-hour measurement period, its uptime is 95%.
However, operators should distinguish between a charger being online, being available to drivers and successfully completing charging sessions. These measures do not always mean the same thing.
What causes EV charger downtime?
Charger downtime can happen for several reasons:
- Hardware faults or damaged components.
- Network connectivity problems.
- Power supply interruptions.
- Software or communication issues.
- Maintenance and repairs.
Identifying the underlying cause is important because different issues require different solutions.
How can operators improve charger uptime?
Operators can take several steps to improve network reliability:
- Monitor charger status: Keep track of charger availability and connectivity.
- Identify faults early: Use alerts and diagnostic information to investigate problems.
- Review performance data: Look for recurring issues across chargers and locations.
- Maintain equipment: Follow appropriate inspection and maintenance schedules.
- Coordinate operations: Make sure teams can access the information needed to investigate and resolve incidents.
Reliable operations depend on both the charging hardware and the systems used to manage it.
How does Electric Miles help operators manage charger performance?
Electric Miles’ emPACT enterprise Charge Point Management System (CPMS) gives CPOs and commercial charging teams a central platform for managing charging infrastructure.
It supports charger monitoring, charging-session visibility and diagnostics, alongside driver management, access permissions, tariffs and operational reporting.
This helps teams view network activity and investigate charger issues without managing every location separately.
emPACT supports operational visibility; actual uptime depends on charger hardware, connectivity, maintenance and site conditions.

Frequently asked questions
What is a good EV charger uptime percentage?
The appropriate target depends on the network, charger type and service commitments. Operators should define how uptime is measured and distinguish availability from successful charging.
Does an online charger always mean it is working?
No. A charger may appear connected but still be unable to complete a charging session.
Can software prevent charger downtime?
Software cannot prevent every hardware or power-related fault, but monitoring and diagnostic information can help operators identify and investigate problems more effectively.
