ICE to EV Conversions and the Role of 3D Scanning

Recent Posts

The automotive industry is currently undergoing a monumental transformation, marked by a resolute shift towards sustainability and environmental consciousness. Among the pivotal trends arising from this shift is the conversion of Internal Combustion Engine (ICE) vehicles to Electric Vehicles (EVs). However, this type of conversion is far from a mere engine swap; it demands an intricate merge of engineering prowess, precision, and innovation. Standing tall in this transformation is the use of 3D scanning technology, which has brought accuracy and efficiency into the ICE to EV conversion process.

The Difficulty With Converting ICE to EV

Today’s vehicles are complex ensembles of various components that must work seamlessly together. The conversion process involves the integration of new EV components into the existing structure and each vehicle presents a unique set of characteristics and challenges. So first we must create the sanitised platform on which the EV elements will be fitted to, on and around.

The Process of Converting an ICE Vehicle to an EV

Step 1: Removal of the ICE components and 3D Scanning

The conversion process from an Internal Combustion Engine (ICE) vehicle to an Electric Vehicle (EV) begins with the meticulous removal of the ICE components. This involves extracting the engine, transmission, exhaust system, and associated components like the fuel pump, radiator, and cooling systems. The fuel tank is also taken out  to make space for the new components of the EV conversion, including the batteries and electric motors. 

Now is also the perfect time to scan in and digitise the empty shell. 

The Role of 3D Scanning

In the automotive world, precision is not just a requirement; it’s a prerequisite for success. A slight misfit or miscalculation can lead to a cascade of issues, from inefficiency in energy utilisation to jeopardised safety.

But how does 3D scanning redefine the conversion process? Capturing millions of data points from the surface of an object, these data points are then transformed into a detailed digital 3D model yielding an in-depth representation of the object’s shape and dimensions. This ensures every aspect of the vehicle that can be meticulously scanned is subjected to comprehensive analysis and digital replication. Conventional methods often relied on manual measurements, which were invariably prone to human error. In stark contrast, 3D scanning provides measurements accurate down to the millimetre, ensuring that even the most minuscule dimension is captured with precision. 

3D scanning shines by creating a virtual sandbox where engineers can test numerous configurations before embarking on any physical work. This approach not only accelerates the planning phase but also minimises the risk of errors during integration.

Step 2: Design & Planning

With the 3D scan processed and in place, engineers are now able to design the component layout in a digital, infinitely adjustable world that can be used to ensure the placements avoid clash conditions, are balanced and are safe. 

Precise Spatial Planning

The precise spatial arrangement of essential components like electric motors, battery packs, and cooling systems can be achieved through the utilisation of 3D scan data of the current shell and CAD models of new EV parts. These digital models provide dependable information about dimensions, shapes, and placements, allowing engineers to make adjustments within a virtual environment while ensuring accurate positioning. This enables engineers to strategically design the configuration of crucial elements identifying potential collisions, interferences, or spatial constraints before any physical integration takes place. This virtual collision avoidance minimises the risk of costly errors during the physical conversion process. 

Optimal Weight Distribution

Batteries, currently, invariably add a lot of weight so achieving balanced weight distribution is essential for stability and performance. Engineers can evaluate how the added weight of batteries and motors impacts the vehicle’s centre of gravity. Through simulations, adjustments can be made to ensure that weight is distributed as evenly as possible, preserving the vehicle’s handling characteristics and safety.

Step 3: Into the Physical World

Now the fitment and design work has been completed, it’s time to transfer this into reality. Fabricated, mounting points, custom channels and reinforced structures are all elements to this phase along with the installation of the EV components 

Power Delivery

One of the core elements of an EV conversion is the integration of electric motors. These motors replace the traditional combustion engine and are connected to the vehicle’s drivetrain. The positioning and alignment of the motors require careful planning to ensure optimal performance and efficient power distribution to the wheels.

Integrating batteries is a pivotal aspect of the conversion process. High-capacity lithium-ion or other advanced battery technologies are used to power the electric motors. The location of the battery pack is strategically chosen, often replacing the space formerly occupied by the engine or utilising other vacant areas within the vehicle’s chassis synch as the fuel tank cavity. Ensuring proper weight distribution and structural integrity are critical considerations during battery placement.

The conversion necessitates the addition of power management and control systems. These systems manage the flow of electricity from the batteries to the motors, ensuring smooth acceleration, deceleration, and energy regeneration. 

In addition, the electrical system of the vehicle undergoes substantial rewiring to accommodate the new components.

Thermal Management

Electric motors and batteries generate heat during operation, necessitating effective cooling and thermal management solutions. Coolants and cooling systems are integrated to maintain optimal operating temperatures and prevent overheating. Proper thermal management ensures the longevity and efficiency of the EV’s components.

Safety Considerations

Reinforcements may be added to the chassis to accommodate the weight and structural changes caused by the new components. Additionally, fire suppression systems and emergency shut-off mechanisms are incorporated to mitigate potential hazards associated with high-voltage systems.

Validation & Performance Optimisation

After the physical integration of components, extensive testing and validation procedures are conducted. These include functional tests of the powertrain, battery systems, and safety features. Road tests evaluate the overall performance, handling, and range of the converted EV. The vehicle must adhere to stringent safety standards and regulations before being deemed roadworthy.

To achieve the best performance and efficiency, fine-tuning is often necessary. Engineers may adjust power delivery, torque distribution, regenerative braking, and other parameters through software updates. These optimisations aim to maximise the vehicle’s range, acceleration, and overall driving experience.

A Vision Forward: The Path Ahead for 3D Scanning

As 3D scanning technology continues to evolve, we can anticipate an array of remarkable innovations in the ICE to EV conversion process. Picture AI-powered simulations that predict performance outcomes based on varying conversion scenarios. 3D scanning has emerged as the linchpin of ICE to EV conversions with its ability to digitise the existing world and create usable 3D data where it is unobtainable. It’s reshaping the manner in which vehicles transition from conventional combustion to electrified power where the link between old and new occurs seamlessly and the road ahead is both electrifying and sustainable.
