What to measure? | Important KPI for CPO , EMSP & EV Charger manufacturers

​

You can’t improve what you don’t measure” once said a wise man! So, which KPIs should an EV charger business monitor, whether it is a maker, network, or operator (CPO)? Here are some key performance indicators for a few functional categories:

📈 Product (reliability & availability):  

🔺 Charging station uptime, which tracks the percentage of time stations are operational and available to charge vehicles. 

🔺 Charging session utilization, which monitors daily/monthly utilization rates per station to understand demand and usage patterns.

🔺 Charge session success rate, which monitors the percentage of successfully completed sessions against total number of sessions. Needs to be accompanied with failure breakdown by cause.

🔺 Payment transaction success rate, which is similar to above but confined to measuring successful completion of payment transactions on EV chargers.

🔺 Cloud connectivity rate, which measures how reliably the charger stays connected to the system backend and communicates.

📈 Business (monetization):

🔺 Revenue per station, which tracks total revenue generated by each charging station. Allows optimization of pricing and locations.

🔺 Energy costs, which track electricity costs per charging station to maintain profitability.

🔺 Maintenance costs, which monitor maintenance outlays per station to reduce operating costs.

🔺 Charging network growth, which tracks total stations deployed and geographic coverage to evaluate expansion.

🔺 Market share, which estimates market share in key regions compared to competing providers.

📈 Customer (satisfaction):

🔺 Charging speed, which monitors average kilowatts delivered per session. Important for service quality and customer experience!

🔺 Customer wait times, which tracks peak wait times at each station to ensure adequate capacity.

🔺 App ratings/reviews, which monitors app store ratings and reviews to gauge customer satisfaction.
