Your guide to dedicated EV plateforms. [?alert: Long article].

I am truly impressed by dedicated EV platforms.

These platforms are redefining the way we perceive and experience electric mobility, offering a host of advantages that cater to both consumers and manufacturers alike.

While this article may be extensive, I am unwilling to compromise, as I am determined for you to be equally impressed.

Understanding dedicated EV platforms: A technical overview

At its core, a dedicated electric vehicle platform is purpose-built from the ground up with EVs in mind. Known as 'ground-up,' 'skateboard,' or 'bespoke' architectures, these platforms are designed exclusively to accommodate electric drive units, large battery packs, and sophisticated climate control and electronic systems.

The technical advantages of dedicated EV platforms:

The standout feature of these platforms lies in their skateboard design – a flat plane that optimally houses the battery and electric motors. Prominent electric vehicles like the Tesla Model 3, Hyundai Ioniq 5, and Volkswagen ID.4 SUVs showcase the efficiency of this approach.

Unlike traditional internal combustion engine (ICE) cars, EVs boast significantly fewer moving parts, approximately 20 compared to the 2000 found in their petrol or diesel counterparts. This reduction allows for a surplus of space within the vehicle, resulting in a roomier interior.

The extended wheelbase in dedicated EVs contributes to a flat and open floor, surpassing the constraints of conventional ICE cars in the same class. This not only provides a more spacious interior but also allows for creative design freedom.

Efficiency takes center stage with the ability to pack more battery modules, optimizing space utilization, reducing unnecessary weight, and enhancing overall performance. This efficiency boost often translates into extended driving ranges, marking a significant leap forward in the capabilities of electric vehicles.

The absence of an engine at the front allows dedicated EVs to sport a shorter bonnet or overhang, potentially offering additional storage space commonly referred to as a 'frunk.'

The fluidity of design and manufacturing:

The simplicity and modularity of EV underpinnings not only open the door to improved efficiency but also empower car designers to experiment with proportions. The adaptability of dedicated EV platforms across various vehicle sizes streamlines development times and slashes investment costs for manufacturers.

Beyond mere cost-effectiveness, these platforms designed exclusively for EVs may result in superior driving dynamics, enhanced structural rigidity, and a lighter overall weight due to optimized packaging. The marriage of form and function takes center stage, offering a tantalizing glimpse into the future of automotive design.

Addressing shared EV/ICE Platforms:

It's crucial to acknowledge that not all electric vehicles benefit from dedicated platforms. EV models adapted to conventional ICE platforms may suffer from inefficient packaging of internal space. Examples include the MG ZS EV, Polestar 2, and Mercedes-Benz EQA electric cars.

The drawbacks of shared platforms may include a shorter wheelbase, reduced interior space, remnants of ICE configurations like a rear row center transmission hump, and potential compromises in storage and design.

Examples of the dedicated EV Platforms:

Several pioneering car manufacturers have embraced dedicated EV platforms, pushing the boundaries of innovation and redefining the electric driving experience.

Tesla's Dual Generations:

Tesla, has set the benchmark with two generations of dedicated EV platforms. The second-generation platform underpins the immensely popular Model 3 electric sedan and Model Y electric SUV, democratizing electric cars with sub-$100,000 offerings that have become global bestsellers.

The first-generation Tesla platform, introduced in 2012, revolutionized the industry with the Model S large sedan and Model X three-row SUV. Luxurious, efficient, and still relevant today, these vehicles showcase Tesla's commitment to pioneering design and functionality.

BYD's E-Platform 3.0:

The Build Your Dreams (BYD) third-generation dedicated EV platform, introduced in 2021, stands out for its integration of proprietary and durable lithium-iron-phosphate (LFP) Blade Battery modules. This unique feature enhances torsional rigidity and sets the stage for advanced capabilities, including 800-volt class charging and up to 1000km of driving range.
