Comparing Battery Technology
An EV is only as good as its battery and here both Tesla and BYD are heavyweights. BYD originally built its business on batteries and its EVs showcase that deep expertise. As The Economist reported, "BYD makes its own batteries, a technology on which all else depends, and does so on a huge scale." [1]
The centerpiece is BYD‘s Blade Battery, formally launched in 2020. This LFP (lithium iron phosphate) battery boasts a unique long and thin cell-to-pack design, eliminating conventional modules. BYD claims this improves space utilization by over 50% compared to standard batteries. [2] The Blade Battery also supposedly provides superior safety and charging performance. In one test, BYD showed its battery remained stable after been penetrated by a nail. [3]
Tesla initially relied on Panasonic batteries but has moved to produce more cells in-house, including its new tabless 4680 cells. According to Elon Musk, these cells boost energy density 5X, power output 6X and range 16% compared to previous cells. [4] Tesla‘s vertical integration of battery production is seen as a key advantage. Its work on new chemistries like high-nickel cathodes and silicon anodes is also on the cutting edge.
Still, many experts believe LFP batteries like BYD‘s are the future for their stability, longevity and avoidance of scarce components like cobalt. According to Shirley Meng, a battery expert at University of California San Diego, "LFP is a very stable chemistry, and stability is key." Tesla recently said it will use more LFP batteries globally.
So while both Tesla and BYD are battery leaders, BYD may have a slight advantage due to its unique Blade Battery technology and long experience in this area. The scale and vertical integration of both companies‘ battery operations is a major asset.
Software and Tech Features
Beyond the core hardware, Tesla prides itself on offering a cutting-edge software experience in its vehicles. Its crown jewel is the Autopilot self-driving system which combines radar, ultrasonic sensors and 8 external cameras. A computer processes the data to enable adaptive cruise control, lane-keeping and other driver assistance features. Tesla‘s more advanced Full Self-Driving package, despite the misleading name, can autopark, change lanes and stop at traffic lights.[5]
In 2019 Tesla unveiled its in-house FSD Neural Network chip to power Autopilot. Since then Tesla has made large improvements to its autonomous driving software stack and FSD beta users now number over 250,000 [6]. Tesla‘s large vehicle fleet provides a feedback loop to train its AI via billions of miles driven. Musk has claimed Tesla will solve self-driving soon.
BYD‘s DiPilot system competes with basic Autopilot in offering adaptive cruise control, lane centering and traffic sign recognition. But BYD has not yet matched the more advanced autonomous capabilities of Tesla‘s FSD. Recent job postings show BYD is working on its own self-driving chip, however, as it invests more in this area.
Beyond autonomy, the "tech" features of Tesla and BYD vehicles are fairly comparable with large touchscreens, over-the-air updates, voice commands, and phone-as-key functionality. Tesla may have an edge in the user experience and interface. In a 2021 UX benchmark study by Munro & Associates, the Tesla Model 3 scored an 86% usability score compared to 60% for BYD‘s Han.[7]
Both companies see the car as a connected device and platform for services. Tesla monetizes features like in-car gaming, video streaming and "premium connectivity" with a web browser and streaming music. The ability of Teslas to serve as fun "gadgets" is a selling point. While BYD doesn‘t yet have as robust an ecosystem, it is exploring infotainment and service subscriptions in its vehicles too.
Charging Infrastructure
An overlooked aspect of the EV "tech stack" is charging infrastructure. Tesla‘s Supercharger network, with over 35,000 chargers globally, is a key competitive advantage. The reliability, convenience and integration of Superchargers into Tesla‘s vehicles and navigation systems creates a seamless fast-charging experience. 95% of Supercharger locations are open 24/7 according to a 2022 Plugshare report.[8]
In China, the charging networks of third-parties like the state-owned TELD are more dominant than any dedicated automaker network. BYD doesn‘t need to build out its own chargers as much since the public network is fairly robust. Still, BYD has installed over 50,000 of its own fast-charging terminals.[9]
As BYD expands to new markets, it remains to be seen if it will invest in its own branded charging network. BYD‘s lower-priced EVs may rely more on home charging in any case. Tesla‘s first-party charging infrastructure, especially in the US, remains a technological edge and selling point for the brand.
Other Energy Initiatives
Tesla and BYD both aim to be more than automakers – they want to accelerate the clean energy transition on a grand scale. Tesla‘s solar and energy storage products like Powerwall and Megapack have become a significant business, generating $2.8 billion in revenue in 2022.[10]
Tesla‘s large utility-scale battery installations have helped stabilize electric grids by storing excess solar and wind power. For example, its Hornsdale Power Reserve in Australia, with 150 MW of capacity, is the largest lithium ion battery in the world and has reduced grid outages.[11]
BYD also has a New Energy division that makes solar panels, energy storage systems and large electric buses/trucks. The company has delivered over 70,000 electric buses globally and its electric sanitation vehicles collect trash in US cities.[12] Like Tesla, BYD sees EVs as part of an "ecosystem" that also spans charging infrastructure, energy generation, stationary storage, and more sustainable vehicles across light and heavy duty sectors.
While BYD may have more diverse energy products and commercial vehicle expertise, Tesla‘s battery storage and solar initiatives are more technologically advanced. Tesla‘s 2020 Battery Day demonstrated its ambitious plans for a terawatt-scale battery production and $25,000 EV, enabled by cell design and manufacturing innovations.[13] Tesla is attacking the renewable energy challenge with the mindset of a world-class tech company.
Conclusion
After this detailed analysis, it‘s clear that both Tesla and BYD are technology leaders pushing the boundaries of what‘s possible with electric vehicles and renewable energy. Tesla still has the overall edge over BYD in EV technology, especially its self-driving capabilities, charging network, and avant-garde battery innovations. Many automotive experts see Tesla as more tech-forward.
However, BYD‘s EV technology is highly competitive with Tesla‘s while being dramatically cheaper. The company‘s Blade Battery, autonomous development, and software show it cannot be underestimated. BYD‘s more diversified manufacturing and product lines in areas like energy storage and commercial vehicles are also advantages from a business standpoint.
At the end of the day, both companies have immense technological strengths. How Tesla and BYD execute their digital transformation strategies, from factory automation to new business models, may determine the winner of this EV arms race in the long run. What‘s certain is these two pioneers, led by visionary technologists, will keep electrifying and digitizing the automotive value chain. Consumers and the planet will be the ultimate beneficiaries of their innovations.
