Crazy Rich China | Electric Vehicles, EV Batteries and the New Car Industry begins with a familiar object that has quietly become one of the largest industrial transformations of the decade: the car.
Did you know? The International Energy Agency reported that nearly 75% of the world’s electric cars were produced in China in 2025. More than 13 million electric cars were sold in China that year, and electric models accounted for close to 55% of new-car sales.
That makes China electric vehicles, Chinese EVs, EV batteries, BYD, China car industry and new energy vehicles more than automotive search terms. They point toward a dense system linking batteries, software, factories, charging, minerals, electronics, exports and consumer behaviour.
The interesting story is not that China makes many EVs. The interesting story is how many industrial layers had to align before that became possible.
Did You Know? China Became the Centre of Global EV Production
The IEA’s Global EV Outlook 2026 estimated that nearly 22 million electric cars were produced worldwide in 2025.
China produced about 16 million of them. That is an extraordinary concentration of manufacturing capability.
Scale alone does not guarantee permanent advantage, but scale accelerates learning. More factories, suppliers, engineers, batteries, vehicles and customers create more opportunities to reduce cost, improve processes and test new designs.
The EV Is Not One Industry
An electric vehicle looks like one product because it arrives as one car.
Economically, it is a stack of industries.
- battery cells and battery packs;
- cathode and anode materials;
- power electronics and semiconductors;
- electric motors;
- vehicle software;
- thermal management;
- charging equipment;
- precision stamping and casting;
- glass, steel, aluminium and polymers;
- sensors and driver-assistance systems;
- logistics and dealer networks; and
- recycling and end-of-life systems.
The Battery Is the Strategic Heart of the Vehicle
In a conventional car, the engine dominates the mental picture. In an EV, the battery becomes central to cost, range, weight, charging speed and performance.
That is why battery manufacturing matters so much.
The IEA estimated that China accounted for more than 80% of global battery-cell production in 2025, alongside very large shares of cathode and anode active-material production.
The car is therefore connected to an upstream materials and electrochemistry system long before it reaches a showroom.
Why Cost Matters More Than Glamour
Luxury cars create headlines, but mass adoption is an economics problem.
For EVs to move from novelty to normality, manufacturers must reduce the cost of batteries, electronics, production, distribution and ownership.
China’s intense domestic competition has pushed automakers to improve specifications while fighting aggressively on price. That pressure is uncomfortable for companies, but it can accelerate product learning for the industry as a whole.
More Than Half of New Cars Sold in China Were Electric in 2025
The IEA estimated that close to 55% of new cars sold in China in 2025 were electric.
That is a useful threshold because a technology behaves differently when it moves beyond a niche.
Once many neighbours, taxi fleets, delivery drivers and family members use EVs, charging, maintenance knowledge, second-hand markets and consumer expectations begin to normalise around them.
Charging Is Part of the Product
An EV is only as useful as the system that lets people recharge it.
That means the user experience extends beyond the car. Home charging, workplace charging, public fast charging, parking policy, electricity supply and route planning all become part of mobility.
This is a classic systems lesson: the product boundary is larger than the physical object.
Software Changed What a Car Company Needs to Know
Modern EVs contain large amounts of software.
Drivers increasingly interact with the car through screens, navigation systems, over-the-air updates, driver-assistance features and energy-management software.
That changes competitive capability. A strong automaker now needs not only mechanical engineering and manufacturing. It also needs software teams, data systems, cybersecurity, user-interface design and rapid update processes.
Chinese EV Exports Became a Global Trade Story
According to the IEA, Chinese electric-car exports doubled in 2025 to more than 2.5 million vehicles.
Exports matter because they move the competition into many different regulatory, pricing and consumer environments.
A car that succeeds domestically still has to meet other countries’ safety rules, charging standards, tariffs, consumer preferences and service expectations.
Southeast Asia Is an Important Test Ground
The IEA reported that Chinese brands accounted for more than half of electric-car sales in Southeast Asia in 2025.
For Singapore readers, that makes the EV story geographically close.
Cars, buses, batteries, charging equipment and mobility software moving through Southeast Asia link China’s manufacturing scale to a region with very different income levels, road systems, policy choices and urban forms.
Industrial Scale Creates a Learning Loop
Imagine two manufacturers. One builds 10,000 units of a new design. Another builds one million.
The larger manufacturer encounters more supplier problems, warranty cases, process variations and customer feedback. If the organisation can capture those lessons, volume becomes a learning engine.
This does not mean big automatically means good. It means repetition creates data—and data can become improvement.
The Real Competition Is Between Ecosystems
A carmaker rarely controls every critical input.
Battery suppliers, chipmakers, software companies, charging operators, logistics providers, materials companies and governments all influence the final outcome.
This is why the EV transition is not simply Tesla versus BYD, or one badge versus another. It is a competition between industrial ecosystems.
What Happens to Petrol Stations?
Large technological transitions often leave old infrastructure in place for years.
Internal-combustion vehicles do not disappear overnight. Fuel stations, workshops and parts networks continue operating while charging infrastructure grows.
The transition therefore produces overlap. Old and new systems coexist, compete and adapt.
Students should notice this because real technological change is usually messier than a before-and-after diagram.
Battery Recycling Will Matter More as the Fleet Ages
The first phase of an EV boom is about manufacturing and sales.
The later phase increasingly includes repair, repurposing, second-life uses and recycling.
A battery contains valuable materials and embodied energy. Recovering those materials efficiently can reduce waste and create a circular industrial layer around the vehicle fleet.
What Singapore Can Learn from China’s EV Scale
Singapore’s car market is tiny compared with China’s, but the systems comparison is still useful.
Singapore’s policy challenge involves electrification inside a compact, land-constrained city with dense public transport. China’s challenge involves enormous manufacturing scale and a continental road network.

Ten Vocabulary Words for Reading the EV Industry
A good reader does not memorise brands first. Learn the system vocabulary.
- battery cell — the electrochemical unit that stores electrical energy;
- battery pack — an assembled system of cells with structure, cooling and control;
- cathode — one of the battery’s key electrode components;
- anode — the complementary electrode component;
- power electronics — hardware that controls and converts electrical power;
- inverter — a device that converts electrical current into the form needed by the motor;
- thermal management — controlling temperatures in batteries and electronics;
- charging curve — how charging power changes as battery state changes;
- vertical integration — owning or controlling several stages of the supply chain; and
- economies of scale — lower average costs that can result when production volume rises.

The Car Became a Technology Platform
For most of the twentieth century, people could explain a car primarily through mechanical engineering.
That is no longer enough.
An electric car is chemistry, software, power electronics, manufacturing, infrastructure and data travelling together on four wheels.
Did you know? That is why China’s EV boom matters even to people who never buy a Chinese car. It is a demonstration of what happens when an old industrial object is rebuilt around a new technological stack.
