Comprehensive Guide to Selecting the Best Industrial Display for EV Chargers

As the adoption of electric vehicles (EVs) surges, the need for reliable and user-friendly EV charging stations becomes critical. A key aspect that ensures an efficient charging experience is the industrial display used in the EV chargers. The right display improves user interaction, enhances visibility, and withstands harsh environmental conditions. This guide explores in depth the essential factors that should be considered when choosing an industrial display for EV charging stations.

Types of Displays: Making the Right Choice

The display type you choose plays a major role in both user experience and functionality. There are three main types of industrial displays commonly used in EV chargers:

1. LCD (Liquid Crystal Display):
• LCDs are well known for their energy efficiency and clear visibility under various lighting conditions, especially in direct sunlight.
• They are cost-effective, and often come in a wide range of sizes, making them a popular choice for outdoor displays.
• However, the brightness and color saturation may not match the other available technologies.
2. LED (Light Emitting Diode):
• LED displays are highly efficient and provide brighter visuals with superior energy-saving capabilities.
• These displays have a long lifespan, with reduced power consumption compared to traditional LCDs, making them ideal for 24/7 operational needs like EV chargers.
• The enhanced brightness of LED screens makes them perfect for outdoor installations, especially in brightly lit areas.
3. OLED (Organic Light Emitting Diode):
• OLED technology provides unparalleled contrast, vibrant colors, and sharp clarity.
• With its ability to create thinner, flexible displays, OLEDs are increasingly preferred for compact design requirements in modern EV charging units.
• They do, however, come with higher costs, and in some cases, their lifespan might not match LED displays.

Size and Resolution: Enhancing User Experience

When determining the size and resolution of your display, the goal is to strike a balance between clarity and efficient use of space.

• Screen Size: The typical recommendation for EV charger displays is between 7 to 15 inches. This size is optimal for user interaction, providing sufficient space for critical information without making the unit bulky or overwhelming.
• Resolution: High resolution is vital for readability, ensuring that text and graphics are sharp and easy to interpret. A minimum resolution of 720p (1280 x 720) is recommended, though Full HD (1920 x 1080) or higher resolutions are preferable for top-tier clarity, especially when displaying complex information like maps, graphs, or live status updates.

Durability and Environmental Resistance

EV chargers are often installed outdoors, meaning the display must endure various environmental challenges such as rain, extreme temperatures, dust, and even vandalism. The durability of an industrial display is defined by several critical factors:

1. IP Rating (Ingress Protection):
• The IP65 rating is a must for outdoor EV charger displays. It signifies complete protection against dust ingress and protection against water jets, ensuring the display will function reliably even in harsh weather conditions.
2. Operating Temperature Range:
• EV charger displays must function reliably in environments that fluctuate between extreme cold and heat. Ideally, choose a display that operates between -20°C to 60°C for year-round performance, from hot summers to freezing winters.
3. Vandal Resistance:
• It is essential to opt for displays with toughened or anti-shatter glass that can withstand physical impacts, ensuring longevity and security in public installations.
• Additional protective layers like scratch-resistant coatings can further enhance durability.

Touchscreen Technology: A Step Toward Interactivity

Incorporating a touchscreen enhances user experience by allowing direct interaction with the EV charging system. The two main types of touchscreen technology used in industrial applications are:

• Capacitive Touchscreens:
• These are highly responsive, support multi-touch gestures, and offer a modern, intuitive user experience.
• Capacitive screens are ideal for environments where users might interact with the display using their bare fingers, offering better sensitivity than resistive screens.
• Resistive Touchscreens:
• While slightly less responsive, resistive touchscreens are more durable and can be used with gloves or styluses, making them suitable for colder climates or industrial settings.
• They are more resistant to contaminants like dirt or liquids, which can interfere with capacitive screens.

Regardless of the technology, the touchscreen surface should be scratch-resistant and rugged enough to endure frequent usage in public spaces.

Integration and Connectivity: Ensuring Compatibility

When selecting a display for an EV charger, it’s crucial to consider its ability to seamlessly integrate with the charger’s control system and other peripherals.

1. Connectivity Options:
• Ensure the display supports multiple connection types like HDMI, VGA, USB, and Ethernet, allowing compatibility with diverse systems and future-proofing the installation for upgrades or modifications.
2. Software Compatibility:
• The display should easily interface with the existing charging management software and the underlying operating systems. Most industrial displays today are compatible with both Android and Windows platforms.

Energy Efficiency: Keeping Costs Down

As EV chargers are typically operational 24/7, power consumption is a crucial consideration. Choosing an energy-efficient display helps keep operational costs low without sacrificing performance. Both LED and OLED displays are superior to traditional LCDs in terms of energy consumption.

• LED displays are the most balanced option, combining excellent brightness and energy savings. OLED displays, while more expensive upfront, also offer notable energy efficiency and superior image quality.

Cost vs. Quality: Finding the Sweet Spot

While it’s tempting to opt for cheaper displays, it's important to consider the total cost of ownership. Lower-cost displays may require frequent maintenance or replacements, leading to higher costs in the long term. Always consider factors like:

• Warranty: Look for a comprehensive warranty, ideally covering 2 to 3 years, which provides peace of mind in case of defects or early failure.
• Durability: Paying extra for a durable, vandal-resistant display will save money over time by reducing the need for repairs or replacements.

FAQs about Industrial Displays for EV Chargers

1. What is the ideal screen size for EV chargers?
• A screen size between 7 to 15 inches is typically recommended to offer sufficient space for interaction without taking up excessive space.
2. How important is the IP rating for EV charger displays?
• Extremely important. For outdoor installations, a rating of IP65 or higher ensures protection from dust and water, safeguarding the display from environmental damage.
3. Capacitive vs. Resistive touchscreens—what's the better option for EV chargers?
• Capacitive touchscreens offer better responsiveness and multi-touch functionality, ideal for modern user interaction. Resistive touchscreens are more durable and suitable for use with gloves, making them better for colder climates.
4. How do I ensure my display works in extreme temperatures?
• Choose a display designed for industrial use, with an operating temperature range of -20°C to 60°C, ensuring reliable performance in various weather conditions.
