Overtaking Tesla in EV Production

I retired while working at Tier 1s in the world of American and German automotive companies. If I was not in China or the Philippines, I was in western and eastern Europe going to suppliers. Mostly, this was automotive component production for American automobiles and pickups.

As you read this piece, I believe you will realize how BVD has surpassed other manufacturers, not just Tesla. BVD appears to control all of the inputs in what is old technology called vertical integration. Each layer is linked and they feed off of each other supplying information and dates of delivery. Raw material weaved together with production needs and supply chain to plan materials and product demands.

This is not something terribly new as it was once MRPII and then ERP. Both of which demand was fed into and giving purchasing, planning and manufacturing direction. Demand information fed to suppliers for material and components and manufacturing planning capacity and shifts to meet demand.

BYD has surged onto the global stage, challenging industry giants like Tesla with its aggressive expansion and pioneering battery technology. BYD’s production soared from half a million to over 4 million vehicles. As the company celebrates its 30th anniversary, its blend of vertical integration, cutting-edge automation, and global supply chain mastery has redefined the EV landscape.

In recent years, Chinese carmaker BYD has experienced remarkable growth and success. The numbers tell a compelling story: BYD’s production has surged from approximately 500,000 units to over 4 million in almost seven years. This represents an over 700% increase, a clear indicator of the company’s aggressive expansion strategy. BYD nearly caught up to Tesla in 2024 pure EV deliveries (1.76 million vs. 1.79 million) but stole the show with plug-in hybrids, firmly securing its spot as the world’s top new energy vehicle maker.

It didn’t stop there; BYD surged past Tesla in Q3 revenue, bringing in $28.2 billion to Tesla’s $25.18 billion. December marked yet another milestone with BYD’s 10 millionth plug-in vehicle rolling off the line. And all of this comes just in time for the company’s 30th anniversary. This growth, driven by their focus on New Energy Vehicles (NEVs), has propelled them to the forefront of the global automotive industry.

Production network and strategy

BYD’s manufacturing footprint spans multiple continents, with a significant concentration in China. Key facilities include the Xi’an plant in Shaanxi, with an annual production capacity of 900,000 vehicles, and the Changsha plant in Hunan, capable of producing 600,000 vehicles annually. The Hefei facility in Anhui, operational since June 2022, is set to reach a capacity of 1.32 million vehicles upon completion of its three-phase development. Collectively, BYD’s domestic production capacity in China has reached 5.82 million vehicles annually as of 2024.

Battery production and innovation

BYD’s top-notch battery manufacturing lies at the heart of its success in the electric vehicle market. The company’s subsidiary, FinDreams Battery Co., focuses on lithium iron phosphate (LFP) technology, featuring the groundbreaking “Blade Battery,” celebrated for remarkable safety and efficiency. As of December 2023, FinDreams Battery held its place as the world’s second-largest EV battery manufacturer, behind CATL.

To secure a steady supply of critical raw materials, BYD has moved into mining operations. In 2023, the company secured mining rights in Brazil’s “Lithium Valley,” marking its first mining investment beyond China. Looking forward, the company expects to unveil solid-state EV batteries by 2027, aiming to boost energy density and safety.

So how did BYD grow its production volume so rapidly?

BYD’s success in rapidly scaling up to become a leading global EV manufacturer can be largely attributed to a strategic approach that weaves together production innovation, supply chain optimization, and deep vertical integration. Over the past decade, the company has leveraged its heritage in battery production to build a robust ecosystem stretching from raw material sourcing to final vehicle assembly. This strategic control has minimized external dependencies, reducing exposure to both cost fluctuations and supply constraints. At the same time, BYD’s emphasis on advanced production processes has facilitated consistent model rollouts, even amid growing demand across international markets.

1. Vertical integration

One of BYD’s defining strategies has been the in-house production of key components. Rather than relying on external suppliers for core components, BYD manufactures batteries, power electronics, electric motors, and semiconductors in-house. This vertically integrated model became more prominent after the launch of the Blade Battery in 2020, which introduced a new cell-to-pack format, noted for enhanced safety and improved energy density.

2. Platform standardization & modular design

Another crucial element of BYD’s strategy is the use of platform standardisation and modular architecture. The e-Platform 3.0, introduced in 2021, consolidated core EV elements – such as the motor, controller, and chassis – into a single framework. This design reduced parts count and simplified assembly, enabling production lines to switch between different vehicle models with relative ease.

3. Simultaneous engineering & rapid product development

Another crucial factor in BYD’s rise is its simultaneous engineering methodology. Rather than isolating design, engineering, and manufacturing functions, BYD’s teams operate in parallel from the early concept stage through to production. By integrating R&D, design, and manufacturing decisions, BYD can rapidly incorporate new features or rectify potential production hurdles.

4. Automation & gigacasting

High levels of automation have played a key role in BYD’s ability to scale. Automation extends from welding and painting, to pack assembly and final inspection, supported by real-time monitoring systems for quality control. BYD’s Xi’an plant reported 97% automation in 2020, using automated guided vehicles (AGVs), robots, and intelligent warehousing for maximal efficiency.

5. Global supply chain coordination

Beyond China, BYD’s strategy of localizing elements of production—such as electric bus chassis in Hungary and battery assembly in Brazil—demonstrates a flexible, region-specific approach to supply chain management. The ability to source components locally, align logistics precisely with production schedules, and collaborate with regional suppliers ensures stable inventory levels and cost efficiencies.

BYD is aiming for 5-6 million sales by 2025, with Stella Li, CEO of BYD Americas predicting “nearly half” from overseas. Additionally, Li emphasised, “We stand behind our products. As with any groundbreaking technology, there are challenges, but we are committed to ensuring the highest levels of safety and performance,” from a November 2023 statement.

Battery technology remains a key pillar of BYD’s strategy. As a pioneer in blade battery technology, the company is now developing next-generation solid-state batteries, which promise higher energy density, longer lifespan, and improved safety.

In addition to technological advancements, BYD is also focusing on fleet electrification and commercial vehicles, including electric buses and trucks, which are gaining traction globally. The company is further enhancing its models by integrating advanced driver assistance systems (ADAS) as a standard feature, providing cutting-edge safety and automation at no extra cost.
