China EV Supply Chain Shifts: Lidar, Aluminum, India

China’s EV industry is entering a new phase in mid-2026, and the latest developments show that the battleground is no longer just finished vehicles. On July 1 at Electronica China Munich Shanghai, TE Connectivity, Boway Alloy, Jiaocheng Ultrasonic, and Komax signed a four-party strategic agreement to accelerate large-scale “aluminum-for-copper” adoption in automotive wiring. At the same time, China’s lidar sector is scaling rapidly, with Innovusion reporting 271,100 lidar shipments in Q2 2026, up 385% year-on-year, while Indian automotive supply chains are attracting fresh capital as Webasto explores a 2027 IPO for its Indian unit. Together, these stories point to a broader shift: EV competition is being reshaped by materials, sensors, automation, and global manufacturing footprints.

TE and Partners Push Aluminum-for-Copper Into Mass Production

One of the most strategically important announcements came from the automotive materials and connector side of the industry. TE Connectivity joined Boway Alloy, Jiaocheng Ultrasonic, and Komax in a new ecosystem partnership aimed at solving one of the most persistent bottlenecks in EV manufacturing: how to replace copper with aluminum at scale without compromising reliability or manufacturability.

The logic is straightforward.

• China holds only about 3% to 4% of global copper reserves
• It is also the world’s largest copper consumer
• A new energy vehicle typically uses 3 to 4 times more copper than a conventional internal combustion vehicle
• Carmakers are under simultaneous pressure to cut weight, lower costs, and reduce carbon emissions

That makes aluminum substitution more than a cost-saving exercise. It is becoming a supply security and industrial policy issue.

According to TE, its aluminum-based connection solutions can reduce connector component weight by as much as 60%, with more than 6 kg of weight savings per vehicle in some applications. The company also estimates that if these solutions are broadly adopted across China’s auto industry, they could cut more than 1 million tons of CO2 emissions annually.

Estimated Carbon Reduction From TE Aluminum Solutions

What makes this alliance notable is that it addresses the full commercialization chain rather than a single component.

• Boway Alloy contributes high-performance aluminum alloy conductor R&D
• Jiaocheng Ultrasonic provides ultrasonic welding know-how
• Komax brings automated wire harness processing capability
• TE Connectivity leads connector engineering validation and application deployment

This closed-loop approach matters because aluminum substitution has historically faced challenges in connection consistency, welding stability, validation standards, and plant-level production integration. If the four companies can industrialize the process with minimal disruption to existing manufacturing lines, it could materially change EV cost structures in China.

Why Aluminum Matters More in the EV Era

The shift from copper to aluminum is not new in engineering, but EVs make the opportunity more urgent and more valuable.

Compared with copper, aluminum offers:

• Lower weight
• Lower material cost
• Reduced dependence on constrained copper supply
• Better alignment with vehicle lightweighting targets

The trade-off, of course, is that aluminum is more difficult to process in some connection scenarios. Oxidation, joining quality, conductivity optimization, and long-term durability all require careful engineering. That is why TE’s existing portfolio is significant: the company says it has already developed new-generation low-voltage aluminum alloy wire, high-voltage aluminum wire and busbar solutions for EVs, and PDU architectures based on aluminum busbars.

In practical terms, this is the kind of under-the-skin innovation that may not be visible to consumers, but it can have a major impact on:

• vehicle mass
• manufacturing cost
• resource resilience
• lifecycle carbon footprint

For Chinese EV brands pushing into lower price bands while maintaining range and feature content, every kilogram and every yuan matter.

China’s Lidar Market Is Scaling Fast

If aluminum substitution reflects the cost and materials side of the EV race, lidar reflects the intelligence side. The latest shipment data suggests China’s automotive lidar market is moving beyond experimentation and into sustained scale.

On July 7, Innovusion disclosed that its lidar shipments reached about 271,100 units in Q2 2026, up 385% year-on-year and 49% quarter-on-quarter.

This company-specific surge mirrors wider market momentum. According to Gasgoo Research Institute data cited in the source material, China’s passenger vehicle lidar installations exceeded 1.3 million units in January-April 2026.

The market structure is becoming increasingly clear:

• Hesai and Huawei form the leading pair, together accounting for 65.5% of the market
• Innovusion and RoboSense sit in the second tier with meaningful scale and differentiated strategies
• Remaining suppliers hold only a small combined share

Hesai’s position appears especially strong in the core ADAS lidar segment. The company reportedly held 55% share of China’s passenger vehicle primary lidar market in March 2026 and has led the category for 14 consecutive months. Yole Group’s 2026 global automotive report also placed Hesai at 43% global share in ADAS primary lidar shipments.

Huawei, meanwhile, is leveraging the Harmony Intelligent Mobility ecosystem and partner brands to scale its high-end lidar hardware. In March 2026, it launched an 896-line dual-optical-path image-grade lidar, which has already appeared in models including the Maextro S800 and Aito M9, with plans to extend the technology into more partner vehicles.

Robot Applications Are Becoming Lidar’s Second Growth Engine

One of the most important takeaways from the Chinese lidar story is that automotive demand is no longer the only growth driver. Non-automotive applications, especially robotics and embodied AI, are becoming a credible second curve.

RoboSense offers the clearest example.

In Q1 2026, RoboSense reported:

• 330,300 total lidar units sold, up 204.1% year-on-year
• 185,500 robot lidar units sold, up 1,458.8% year-on-year
• Robot applications rising from roughly 11% of sales a year earlier to about 56% of total sales

That means robot lidar sales have already overtaken ADAS within RoboSense’s business mix.

The company has reportedly served more than 3,400 global robotics and adjacent-industry customers, with deployments spanning:

• robotic lawn mowers
• humanoid robots
• industrial robots
• commercial cleaning robots
• autonomous mining trucks
• autonomous delivery vehicles
• Robotaxi platforms

Innovusion is seeing a similar trend at a smaller scale. From January to May 2026, its lidar shipments for robots, industrial solutions, and other non-automotive scenarios reached about 32,300 units, up 1,177% year-on-year. In May alone, monthly shipments in this category surpassed 10,000 units for the first time.

Hesai is also building for this future. The company delivered 118,300 robot lidar units in Q1 2026, up 137.8%, and has created a new strategic growth business focused on physical AI.

Lidar Growth Beyond Cars

This matters because it improves the long-term economics of lidar suppliers. Automotive programs are capital-intensive, qualification cycles are long, and pricing pressure is relentless. A broader customer base across robotics and industrial automation can help smooth revenue, improve factory utilization, and accelerate sensor cost reduction.

Webasto’s India IPO Plan Shows the Supply Chain Is Globalizing

The third development may sit outside China geographically, but it is highly relevant to Chinese EV watchers because it highlights how automotive supply chains are reorganizing around growth markets.

According to reporting cited from the Economic Times, German supplier Webasto is considering a 2027 IPO for its Indian subsidiary, Webasto Roofsystems India, aiming to raise around $400 million to $500 million at a valuation near $2 billion.

The backdrop is strong local demand and ongoing capacity expansion.

Webasto currently supplies sunroof systems to:

• Mahindra & Mahindra
• Tata Motors
• Hyundai Motor India
• Kia India

The company already operates plants in Pune and Chennai, and is building a third factory in Haryana between Manesar and Kharkhoda. That new plant is expected to start production in Q4 2026 and add annual capacity of about 500,000 sunroof systems. Once online, Webasto’s total India sunroof capacity is expected to reach around 2 million units per year.

What stands out is the contrast with Webasto’s global performance. In 2025, group revenue fell 7.4% year-on-year to €4 billion, yet Asia-Pacific’s share of group revenue rose by 4 percentage points to 19%, with India acting as a major growth engine.

This is an important reminder that the future of the auto supply chain is not defined by one market alone. China remains the center of gravity for EV technology and scale, but India is becoming increasingly attractive for manufacturing expansion, capital market activity, and long-term demand growth.

Why This Matters

These three stories may look unrelated at first glance, but together they reveal where the real competition in the EV industry is headed.

1. Material innovation is becoming strategic

The TE-led aluminum-for-copper initiative shows that supply-chain innovation is now deeply tied to energy security, cost control, and carbon reduction. As EV penetration rises, upstream materials engineering will matter more, not less.

2. Lidar is maturing into a scaled industrial category

China’s lidar market is no longer a speculative story. Shipment volumes, customer wins, and model deployment show that lidar has become a core enabler for high-level ADAS in premium and increasingly mainstream vehicles.

3. Robotics could reshape sensor economics

The rise of robot, industrial, and physical-AI lidar demand gives Chinese sensor suppliers a second path to scale. That could reinforce China’s position in both automotive intelligence and next-generation robotics hardware.

4. The supply chain is becoming more geographically diversified

Webasto’s India plans illustrate how global suppliers are balancing China-centric technology ecosystems with manufacturing and capital allocation in other high-growth markets.

Competitive Takeaways for Chinese EV Brands

For automakers such as BYD, NIO, XPeng, Zeekr, Li Auto, Geely, and Aito, these trends have direct implications.

• Lower-cost lightweight wiring could help offset price-war pressure
• More mature lidar supply could accelerate rollout of advanced driver assistance across broader vehicle segments
• Robot-driven lidar scale could reduce component costs over time
• Globalized supplier footprints could diversify sourcing and improve resilience

Brands that integrate these supply-chain advances fastest will have an edge not just in specification sheets, but in margin structure, product timing, and export competitiveness.

Looking Ahead

The next stage of the EV race will be won less by headline launch events and more by deep industrial execution. In China, that means scaling new materials like automotive-grade aluminum conductors, industrializing lidar across both cars and robots, and building supply chains that can stretch beyond domestic borders.

Expect three developments to be worth watching over the next 12 to 18 months:

• whether aluminum-for-copper programs move from pilot validation into broad vehicle-platform adoption
• whether lidar penetration continues expanding beyond premium intelligent EVs into lower price bands
• whether India becomes a more important parallel manufacturing and financing hub for global automotive suppliers

If those trends continue, the winners in the EV era will be the companies that treat hardware, materials, automation, and global capacity as one integrated strategy rather than separate stories.
