Windscreen Replacement for Electric Vehicles: What to Know

As the popularity of electric vehicles (EVs) continues to grow, understanding the unique aspects of their maintenance becomes increasingly essential. One area often overlooked is windscreen replacement. Like curved windshield replacement, EVs require specialized knowledge due to their advanced technology. Here’s everything you need to know about replacing a windscreen for electric vehicles, including the impact of advanced driver assistance systems (ADAS), high voltage systems, and other critical factors that make EV glass replacement unique.

In traditional vehicles, windscreen replacement may seem straightforward. However, electric vehicles (EVs) bring unique challenges due to the integration of high voltage systems, advanced driver assistance systems (ADAS), and specialized cutting-edge technology that enhances safety and performance. 

One of the key features that complicate windscreen replacement in EVs is the reliance on ADAS, which uses cameras, sensors, and radar systems to support functions like lane-keeping, adaptive cruise control, and emergency braking. These systems require precise calibration during the replacement process to maintain their functionality. Any disruption to ADAS alignment caused by an improperly replaced windscreen can compromise the safety features of the electric vehicle, affecting the driver's ability to navigate safely. 

Unique Challenges in Windscreen Replacement for EVs 

1. High Voltage Systems 

Unlike traditional vehicles, electric vehicles (EVs) are powered by high-voltage systems that serve as the backbone of their functionality. These systems, typically operating at 400 to 800 volts or higher, are responsible for driving the motor, powering auxiliary systems, and integrating advanced features like defoggers embedded in the windscreen. During a glass replacement, technicians must carefully deactivate the high-voltage system to prevent electrical shocks, short circuits, or damage to sensitive components. This process often involves isolating the battery, confirming the absence of residual charge, and adhering to manufacturer safety guidelines. 

Beyond the technical challenges, improper handling of high-voltage systems can have significant consequences. Mishandling can lead to severe safety hazards, including electrical shocks or fires, and can also compromise the integrity of the vehicle’s systems. Moreover, manufacturers often stipulate strict protocols for working with EVs, and failing to follow these can void warranties. Only certified professionals with specialized training and tools should attempt glass replacement in EVs to ensure the safety of both the technician and the vehicle owner. 

2. Integration with ADAS Technology 

The integration of advanced driver assistance systems (ADAS) has transformed the complexity of windscreen replacement in EVs. ADAS relies on cameras, sensors, and radar systems, many of which are mounted directly on or near the windscreen. These components enable critical safety features such as lane departure warnings, adaptive cruise control, and emergency braking. When a cracked windscreen is replaced, even a slight misalignment of the camera assembly can result in ADAS malfunctions, such as incorrect lane detection or delayed responses in collision avoidance systems. 

To ensure ADAS functionality is restored after windscreen replacement, precise calibration is essential. This requires advanced diagnostic tools and software capable of recalibrating the cameras and sensors to their factory settings. Technicians must conduct thorough post-installation tests to verify system accuracy. Given the increasing reliance on ADAS in modern vehicles, neglecting proper calibration during OEM glass installation could severely compromise safety and performance. For EV owners, it’s crucial to choose service providers experienced in handling ADAS technology during auto glass repair. 

3. Structural Integrity and Design   

Electric vehicles are designed with lightweight materials and aerodynamic features to maximize energy efficiency. The windscreen plays a crucial role in the structural integrity of these vehicles, acting as a load-bearing element that distributes impact forces during collisions. A properly installed windscreen also supports the vehicle’s aerodynamics, reducing drag and enhancing performance. However, using non-OEM glass or improper installation techniques can weaken the structure, compromising the vehicle’s safety in the event of an accident. 

Additionally, the windscreen serves as a mounting point for critical components, including ADAS sensors and high-tech features like headsup displays. Any misalignment during replacement not only jeopardizes safety but also affects the integration of these technologies. To preserve the vehicle’s design integrity, certified professionals must follow strict guidelines, ensuring that the replacement process adheres to manufacturer specifications. This attention to detail guarantees that the EV remains both safe and efficient after glass replacement. 

Considering Repair or Replacement? 

Deciding between windscreen repair and replacement depends on the size, location, and extent of the damage. A small chip or crack—typically smaller than 3cm—can often be repaired using specialized chip repair techniques, provided it does not obstruct the driver's line of sight or compromise ADAS components like sensors or cameras. However, larger cracks, damage extending to the edges of the windscreen, or chips near critical structural areas usually necessitate a full windshield replacement to ensure safety, maintain structural integrity, and restore the proper functioning of advanced systems. Consulting a professional ensures the right solution for both safety and.

Key Steps in the EV Windscreen Replacement Process   

1. Assessment of the Damaged Windscreen:  The first step involves a thorough inspection of the damaged windscreen to determine the extent and location of the damage. Technicians assess whether the issue can be resolved with chip repair or if a complete windscreen replacement is necessary. Factors like the size of the crack, its proximity to ADAS components, and whether it obstructs the driver’s line of sight influence this decision. For EVs, the assessment also includes checking for embedded technologies, such as defogging elements or solar panels, which require specialized handling. 

2. Deactivating High Voltage Systems:  Before starting the replacement process, the EV’s high-voltage systems must be safely deactivated to prevent electrical hazards. This involves isolating the battery, powering down auxiliary systems, and using specialized tools to confirm there is no residual electrical charge. This step is critical not only for technician safety but also to protect sensitive electronic components that may be impacted by improper handling. 

3. Removing the Old Windshield:  The removal process requires precision to avoid damaging surrounding components, including the camera assembly, sensors, or sealing materials. The old windshield is carefully detached using tools designed for EV glass systems. Special attention is paid to ensure the integrity of the vehicle's frame and the retention of factory-installed adhesives or mounts that are critical for the structural stability of the new OEM glass. 

4. Installing New OEM Glass:  Once the old windshield is removed, the new OEM glass is installed to meet manufacturer specifications. Proper alignment is crucial to maintain the structural integrity of the vehicle and ensure that ADAS components, such as cameras and sensors, function correctly. Technicians use advanced equipment to position the glass precisely, ensuring that it adheres securely to the frame without gaps or misalignment. 

5. Recalibrating ADAS Systems:  After the glass installation, recalibrating the ADAS is a critical step. Misaligned cameras or sensors can disrupt features like lane departure warnings, adaptive cruise control, and emergency braking. Using specialized software and tools, technicians recalibrate the camera assembly and other ADAS components to restore their functionality to factory settings. This ensures the vehicle’s safety systems operate accurately and reliably. 

6. Testing and Inspection:  The final step involves rigorous testing and inspection to ensure the replacement was successful. This includes verifying the proper alignment of the windscreen, checking for leaks, and testing the functionality of recalibrated ADAS systems. Any adjustments required are made during this phase. By the end of the process, technicians confirm that the vehicle meets safety standards and is ready for the road, ensuring peace of mind for the EV owner.
