At Monta we also observe big differences in quality and performance throughout the field\u2014for some charger models, failure rates jump to 40%.<\/p>\n\n\n\n<p>So how can <a href=\"https:\/\/monta.com\/en-us\/business-solutions\/network-operator\/\">network operators<\/a> and installers choose reliable hardware? And what can manufacturers do to improve charger performance to begin with?<\/p>\n\n\n\n<p>We\u2019ve developed a set of objective metrics for measuring quality and performance. Our goal is to help hardware manufacturers understand and improve their performance, and to help network operators make the best decisions as they select hardware.&nbsp;<\/p>\n\n\n\n<p>With profitability and customer satisfaction hinging on the performance of charging infrastructure, making data-driven decisions is critical.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Open Charge Point Protocol (OCPP): How Hardware and Software Work Together<\/h2>\n\n\n\n<p><strong>Open charge point protocol (<\/strong><a href=\"https:\/\/monta.com\/en\/glossary\/open-charge-point-protocol-ocpp\/\"><strong>OCPP<\/strong><\/a><strong>)<\/strong> is an agreed set of communication standards that allows many types of charge points, or chargers, to speak to different <strong>charge point management systems (CPMS)<\/strong>.&nbsp;<\/p>\n\n\n\n<p>Thanks to OCPP, we can compare basic data across different makes and models. But there can be a noticeable difference in how charge points communicate and perform.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How OCPP Data Helps Evaluate Performance<\/h2>\n\n\n\n<p>Most current charging hardware is on the OCPP 1.6 protocol, which was released in 2015. While the new <a href=\"https:\/\/monta.com\/en\/blog\/upgrade-to-ocpp-2-0-1\/\">OCPP 2.0.1<\/a> opens up even more performance and quality measures, OCPP 1.6 still provides valuable data:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Heartbeat messages<\/li>\n\n\n\n<li>Status notifications<\/li>\n\n\n\n<li>Transaction data<\/li>\n\n\n\n<li>Error and fault codes<\/li>\n\n\n\n<li>Firmware management<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How Monta Defines and Measures Hardware Performance<\/h2>\n\n\n\n<p>To make different hardware objectively comparable using OCPP data, Monta developed a standardized ranking system based on 3 key metrics:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Charge Success Rate <\/li>\n\n\n\n<li>Uptime Rate <\/li>\n\n\n\n<li>User Satisfaction Rate<\/li>\n<\/ul>\n\n\n\n<p>Together, the three metrics build the <strong>performance score<\/strong>, which makes one hardware model comparable to another.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Charge Success Rate<\/h3>\n\n\n\n<p>The <strong>charge success rate<\/strong> is the percentage of sessions that result in a successful energy transfer to a vehicle. This measure is critical for drivers, network operators, and manufacturers alike.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Uptime Rate<\/h3>\n\n\n\n<p>The <strong>uptime rate<\/strong> shows how often a specific model is available for drivers to use.&nbsp;<\/p>\n\n\n\n<p>Reliability is key to delivering a best-in-class user experience. Plus, regulations like the National Electric Vehicle Infrastructure (NEVI) Formula Program require uptime to be reported.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">User Satisfaction Rate<\/h3>\n\n\n\n<p>Drivers using <a href=\"https:\/\/monta.com\/en\/monta-charge\/\">Monta Charge<\/a> are welcome to leave comments and a rating of 1 to 5 after completing a charging session. Network operators and hardware manufacturers have direct access to that user feedback in <a href=\"https:\/\/monta.com\/en\/hardware-portal\/\">Monta\u2019s Hardware Portal<\/a>.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Performance Score<\/h3>\n\n\n\n<p>A charger model\u2019s overall <strong>performance score<\/strong><em> <\/em>is calculated once a day, and is an average of its charge success rate, user satisfaction rate, and uptime rate.<\/p>\n\n\n\n<p>Monta\u2019s platform tracks every charger model\u2019s performance scores over a 30-day period. This allows us to reflect how a model performs across all key metrics over time, painting an overall picture of current performance.<\/p>\n\n\n\n<div class=\"wp-block-group pad--s border--shade bg--base-light rounded--l box-shadow--l is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading has-text-align-center\">Want to Learn More?<div><span style=\"box-sizing: border-box; font-weight: 600; font-feature-settings: &quot;ss01&quot;; font-synthesis: none !important;\"><\/span><\/div><\/h3>\n\n\n\n<p class=\"has-text-align-center\"><a href=\"\/en-us\/downloadables\/a-framework-for-evaluating-ev-charging-station-performance\/\">Download this report<\/a> for a full breakdown of how Monta\u2019s scoring system<\/p>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Top AC and DC Chargers According to Monta Users<\/h2>\n\n\n\n<p>If you are a network operator or anyone interested in how EV charging hardware performs, our <a href=\"https:\/\/monta.com\/en\/supported-charge-points\/\">supported charge points list<\/a> is your go-to place. As of today, Monta integrates with more than 600 charger models from over 170 hardware brands.<\/p>\n\n\n\n<p>The charger model with the highest 30-day rolling performance score is ranked first, and so on.<em> <\/em>The rolling average ensures that ranks do not fluctuate heavily on a day-to-day basis, but still represent a trend for the charger model.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Can Hardware Manufacturers Do to Improve Performance?<\/h2>\n\n\n\n<p>\u201cMeasurement is the first step that leads to control and eventually to improvement. If you can\u2019t measure something, you can\u2019t understand it. If you can\u2019t understand it, you can\u2019t control it. If you can\u2019t control it, you can\u2019t improve it.\u201d \u2015 <strong>H. James Harrington<\/strong><\/p>\n\n\n\n<p>All our measures (<em>charge success rate, uptime rate, and user satisfaction rate<\/em>) are a result of many different factors from real charging events along the value chain.&nbsp;<\/p>\n\n\n\n<p>The success or failure of a charge\u2014or a bad user rating\u2014can come down to charger firmware, design oversight, hardware issues on the circuit board, a broken SIM, bad network connection, unstable grid supply, malfunction in the cable, temperature issues, bad installation, OCPP gateway issues, OCPP proxy failures, CPMS problems, configuration issues, authentication errors, and many more.&nbsp;<\/p>\n\n\n\n<p>We strongly believe in using data to analyze where in this complex value chain things might be going wrong. Single installations or network issues will not have a large impact on performance data, but a bug in a firmware release can easily drag down a model performance if it\u2019s deployed widely.&nbsp;<\/p>\n\n\n\n<p>This is why Monta has invested in a <a href=\"https:\/\/monta.com\/en\/hardware-portal\/\">Hardware Portal<\/a> to give manufacturers the tools and data they need to make the most informed decisions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"478\" src=\"https:\/\/monta.com\/app\/uploads\/sites\/23\/2025\/03\/Visual-blog-2-1024x478.png\" alt=\"Line graph displaying Brand Performance scores over 30 days, highlighting Charge Success Rate, Uptime Rate, and User Satisfaction rates in vibrant colors.\" class=\"wp-image-2499\" srcset=\"https:\/\/monta.com\/app\/uploads\/sites\/23\/2025\/03\/Visual-blog-2-1024x478.png 1024w, https:\/\/monta.com\/app\/uploads\/sites\/23\/2025\/03\/Visual-blog-2-300x140.png 300w, https:\/\/monta.com\/app\/uploads\/sites\/23\/2025\/03\/Visual-blog-2-768x359.png 768w, https:\/\/monta.com\/app\/uploads\/sites\/23\/2025\/03\/Visual-blog-2.png 1083w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p><em>One of Monta\u2019s Hardware Portal dashboards<\/em>&nbsp;<\/p>\n\n\n\n<p>They have access to performance data and detailed user feedback for brands, charger models, and even individual devices.
