As the demand for electric vehicles (EVs) continues to rise, the need for efficient and reliable public charging infrastructure becomes increasingly important. One crucial element of this infrastructure is the display used in public EV chargers.
The display provides essential information such as whether the plugged in car is charging, the power output and might also serve as the interaction interface between the users and the charging station.
In this article, we will explore the key requirements to consider when selecting a display for public EV chargers, with a focus on robustness and performance in extreme ambient temperatures since they are subject to a wide range of environmental conditions and potential physical impacts.
Consider the following factors:
Durability: As the display needs to withstand potential vandalism or accidental damage, a strong cover lens is very important and a good choice for this purpose. We usually propose a robust cover glass bonded on the display module to ensure long-term reliability and functionality.
Impact Resistance (IK rating): Public spaces can be bustling, and the display may be susceptible to impact. We recommend bonding the display with a toughened glass or polycarbonate screen to minimize the risk of damage from physical contact. An entry on the advantages of each can be found here.
Temperature Range: The display must be able to operate on a broad temperature range, encompassing both hot summers and cold winters. Extreme temperatures can affect the performance and longevity of the display, so it's crucial to select one that can withstand these variations. Surely end users will not be happy trying to deal with a non responsive screen in the cold.
Sunlight Readability: Ensure that the display has high brightness and good sunlight readability. This is essential for users to interact with the charging station interface easily, even in bright sunlight.
Touchscreen Technology: Capacitive touchscreens provide a more responsive and durable interface compared to resistive touchscreens. They also offer better visibility in varying lighting conditions.
Selecting the right display solution for public EV chargers is a critical decision that directly impacts the user experience and the overall functionality of the charging station. By prioritizing robustness, performance in extreme ambient temperatures and legibility, you can ensure that the display contributes to the success of your public charging infrastructure, making it reliable and user-friendly for all EV users.
