TL;DR: Xiaomi Sunwoda EVB investment explained in one line: Xiaomi is paying ¥1.7 billion (about $253 million) for a 5.34% stake in Sunwoda's electric-vehicle battery unit — becoming its third-largest shareholder, weeks after Li Auto bought in — in a deal that also ends Sunwoda's control of the battery business and scraps its planned Hong Kong listing.
📌 KEY HIGHLIGHTS
- The deal: Xiaomi, through its wholly owned unit Hanxing Venture Capital, will invest ¥1.7 billion in Sunwoda Electric Vehicle Battery Co Ltd (Sunwoda EVB) for a 5.34% stake, per a Sunwoda filing released on the evening of 29 October 2026.
- Who owns what after: Sunwoda stays the largest shareholder at 22.78%, Li Auto stays second at 8.32% (diluted from 8.79%), and Xiaomi becomes third — but Sunwoda will hold no more than half the board seats and lose control of the unit.
- The bigger reshuffle: Sunwoda is also cancelling its planned Hong Kong share listing, and expects the deconsolidation to add ¥3.2–4.5 billion to its 2026 net profit on paper, subject to audit.
- Why Xiaomi is doing it: Sunwoda already makes cells for Xiaomi's Dragon Armour battery, used in its Sky Nomad series. An equity stake buys priority capacity and a say in development — cheaper than building a battery factory.
- Not closed yet: The capital-increase agreement is signed, but the transaction still needs approval from Sunwoda's shareholders.
Xiaomi Sunwoda EVB investment explained: what happened?
Sunwoda Electronic (SZSE: 300207) announced the deal on Thursday evening, 29 October 2026, in a filing to the Shenzhen Stock Exchange, and it was reported the next day by CnEVPost, Shanghai Metals Market, TechNode and others. Xiaomi (HKEX: 1810) is not buying Sunwoda itself. It is buying into Sunwoda EVB, the subsidiary that makes batteries for electric vehicles — a business that reported ¥15.53 billion in revenue but a ¥324 million net loss in the first half of 2026.
The mechanics matter because they explain the headline. Xiaomi's Hanxing Venture Capital will subscribe to ¥897.805 million of newly issued registered capital — that is the new shares being created — for a total cash investment of ¥1.7 billion. The round is described as a C+++ round, priced in line with the previous C round, which values Sunwoda EVB at ¥30.13 billion before the money goes in, or about ¥31.84 billion after it. That is why a ¥1.7 billion cheque buys only 5.34%: the company is already large, with total assets of ¥68.15 billion.

Why Sunwoda is giving up control of its own battery unit
The most surprising part of the filing is not Xiaomi's cheque — it is what happens to Sunwoda. After the capital increase and a planned board reshuffle, Sunwoda will hold no more than half of Sunwoda EVB's board seats. Under accounting rules, that means it no longer controls the unit: Sunwoda EVB stops being a consolidated subsidiary and becomes an associate company, with Sunwoda booking only its share of the unit's earnings instead of its full revenues and losses.
That accounting change is worth real money on paper. Sunwoda preliminarily estimates it will increase its 2026 net profit by ¥3.2–4.5 billion, because the remaining stake gets remeasured at fair value when control is lost — though the final figure is subject to audit. The company says the move lets it focus resources on consumer batteries and energy storage, while cutting its financing needs and its liabilities-to-assets ratio.
The same evening, Sunwoda also terminated its plan to issue H shares and list on the Hong Kong stock exchange — a plan its board and shareholders had approved in July 2025. It cited market conditions, changes within the company and its development plans, and said the cancellation would not materially affect operations. Read together, the two announcements point the same way: instead of raising money from public markets in Hong Kong, Sunwoda is raising it from its own customers — first Li Auto, now Xiaomi.
The context is a parent under pressure. Sunwoda's revenue rose 45.78% year on year to ¥63.46 billion in the first three quarters of 2026, but net profit attributable to shareholders fell 56.37% to ¥613 million, and its shares closed down 4% in Shenzhen on 30 October. A battery unit that loses money while its parent's profits shrink is exactly the kind of asset that gets restructured.

Why Xiaomi and Li Auto both want a piece of the same supplier
This is the second carmaker to buy into Sunwoda EVB in under two months. On 4 September 2026, Sunwoda disclosed that Li Auto planned to invest ¥2.65 billion for a direct 8.79% stake; the two companies had already set up a 50/50 joint venture in 2025 to manufacture Li Auto's in-house developed batteries. Xiaomi's deal dilutes Li Auto to 8.32%, but Li Auto keeps second place.
Xiaomi's relationship with Sunwoda is newer but already operational. On the same day in September, Xiaomi Auto announced strategic partnerships with CALB and Sunwoda EVB to develop its Dragon Armour (Longjia) battery: Xiaomi defines the product and leads pack design, while Sunwoda manufactures the cells and runs dedicated custom production lines. The co-developed batteries are already used in Xiaomi's Sky Nomad series, and Xiaomi said in September that its self-developed batteries would gradually roll out across its model line-up from the second half of 2026.
The logic is the same for both carmakers. The battery is the most expensive component in an electric car, and securing capacity, quality and technology matters more than owning the factory. Building a battery plant costs billions and carries technology risk; a minority stake in an existing supplier buys priority access and a voice in development for a fraction of that. The trade-off is also real: when a carmaker puts money into a battery maker, it shares responsibility for that battery's safety and lifespan, not just its price.
One naming note for readers following Chinese coverage: some Chinese outlets call the unit "Sunwoda Power" rather than Sunwoda EVB. It is the same company — Sunwoda Electric Vehicle Battery Co Ltd — and the figures in this post use the filing-based names and numbers reported by CnEVPost and Shanghai Metals Market.
Why it matters for India readers
Xiaomi does not sell its cars in India, and nothing in this deal changes that — do not read it as an India car launch. What it does show is the direction of the global battery business that India is trying to join. Indian carmakers face the same problem Xiaomi and Li Auto are solving: batteries dominate an EV's cost, and whoever controls cell supply controls pricing, range and delivery dates. India's own answer has been localisation incentives for advanced battery cells, and Tata's EV plans — including the Tata Safari EV due in January 2027 — depend on the same global cell market tightening up here.
For readers who know Xiaomi only as a phone brand — its Xiaomi 18 Pro Max is currently launching in Europe and its Smart Band 11 is on sale in Europe — the deal is a reminder of how far the company has travelled since phones. In under three years it has gone from launching its first car to taking equity stakes in the supply chain behind it, following the same playbook Tesla and BYD used: control the battery, control the car business.
Should you care?
✅ Verdict: Yes, if you follow EVs or Xiaomi — but as a supply-chain story, not a product launch. Two rival carmakers now own stakes in the same battery maker, and the battery maker's parent has handed over control to raise cash from its customers instead of the stock market. That tells you where the EV industry's real fight is: not in showrooms, but in cell factories. ⏳ Watch for: Sunwoda's shareholder vote, and whether Xiaomi's stake turns into dedicated capacity for its next models.
FAQs
Why is Xiaomi investing in Sunwoda EVB?
To secure battery supply. Sunwoda already manufactures cells for Xiaomi's Dragon Armour battery, used in its Sky Nomad series. A 5.34% stake gives Xiaomi priority capacity and a say in development, without the cost and risk of building its own battery factory.
How much did Xiaomi invest in Sunwoda EVB?
¥1.7 billion, about $253 million, through its wholly owned subsidiary Hanxing Venture Capital. The money subscribes to ¥897.805 million of new registered capital, giving Xiaomi a 5.34% stake and making it the unit's third-largest shareholder.
Is Sunwoda still in control of its EV battery unit?
No, not after this deal closes. Sunwoda remains the largest shareholder at 22.78%, but once the board is reshuffled it will hold no more than half the seats, so it loses control and stops consolidating the unit's accounts. Sunwoda EVB becomes an associate company instead.
Will Xiaomi sell its cars in India now?
Nothing in this deal suggests that. Xiaomi's cars are sold in China, and no India car launch has been announced. The deal is about securing battery supply for its existing Chinese vehicle business, though it matters for India because the same battery market sets costs for Indian EVs too.
Takeaway: Xiaomi just bought its way inside its battery supplier — and Sunwoda, under profit pressure, chose its customers' money over a Hong Kong listing. When carmakers start buying the factory, the battery is the business.
