Recently, the project "Independent R&D and Large-scale Industrialization of Key Components and Vehicle Platforms of a New Generation of Electric Vehicles" led by BYD Co., Ltd. won the second prize of the National Science and Technology Progress Award, which is the second time that BYD has won the National Science and Technology Award as the first completion unit. BYD, which takes technology as the king and innovation-oriented as its development concept, also has a very outstanding technical background in the field of commercial vehicles, and has successfully promoted the wave of bus electrification development with its e-platform.
BYD's e-platform 3.0 was released to promote the re-evolution of electric buses
Once upon a time, BYD e-platform 1.0 and 2.0 opened and promoted the development of continental bus electrification, and its bus wheel drive technology, LEP high specific energy lithium iron phosphate battery, high-voltage 6-in-1 electronic control technology and high-efficiency battery liquid cooling technology successfully opened a new pattern in the field of continental buses. Nearly 100,000 units have been delivered worldwide, and the results of many awards have fully demonstrated the success of BYD's e-platform.
With the continuous transformation and climbing of user needs, the pace of development of electric bus technology has become more urgent. BYD's pure electric bus e-platform 3.0 came into being in this context.
The biggest advantage of the pure electric bus e-platform 3.0 is that it is based on BYD's strong self-research and self-control capabilities, which relies on the manufacturing capabilities of the whole industry chain and the in-depth understanding of the whole vehicle and parts to improve safety, efficiency and intelligence to a new height.
In terms of battery, the pure electric bus E platform 3.0 is based on large-capacity, long-blade cells to create ultra-thin blade batteries, which effectively improves space utilization while also has 9 layers of protection, and has passed multiple tests such as rolling and soaking in water that far exceed national standards.
At the same time, the pure electric bus e-platform 3.0 also adopts the battery-chassis integration (CTC) technology, which not only reduces the weight of the vehicle, but also effectively improves the stability of the vehicle, so that the battery full bottom power of the 12m low-floor model can reach up to 425kWh, taking into account the range and safety.
In terms of efficiency, the e-platform 3.0 of pure electric buses pioneered a 900V silicon carbide six-in-one electronic control system, which reduced the weight of the electronic control by 22%. Its flat wire motor is made of 0.25mm ultra-thin silicon steel sheet, which reduces energy consumption by more than 2%.
More importantly, the e-platform 3.0 of the pure electric bus is equipped with a dual-gun 500A charging solution, and the maximum charging power of the dual-gun can reach 375kW. In addition, it has a new highly integrated thermal management system, which reduces weight by 10%, volume by 25%, and waste heat recovery rate by up to 65%, so as to achieve energy coupling, recovery and reuse.
In addition, BYD's pure electric bus e-platform 3.0 can also realize a variety of auxiliary driving functions and intelligent networked fleet management functions, making driving control more intelligent and fleet management more efficient, so that the majority of users can get a very comfortable experience.
The first model of the bus e-platform 3.0 was unveiled The new version of the B10 came with glory
BYD has always adhered to the principle of mass production when it is released and delivered when it is launched, and the first pure electric bus built based on the bus e-platform 3.0, the new version of the B10 model, was released during the 2024 Beijing Road Transport Vehicle Exhibition held earlier.
The all-new B10 model, based on the bus e-platform 3.0, is equipped with a high-efficiency drive assembly, and its high-efficiency energy flow management technology and lightweight body technology reduce the energy consumption of the vehicle by 15%.
In addition, thanks to the Battery-Chassis Integration (CTC) technology, the new B10 model has improved handling performance by 20%, making it the most roll stable model in the industry. Thanks to the standard independent suspension, the turning radius has been reduced by 8%, making the vehicle more agile and more comfortable on city roads.
Moreover, the new version of the B10 model has a height of only 3160mm, which is the lowest in the industry for similar products, allowing it to travel unhindered in the culvert elevated. In addition, the vehicle's 311kWh battery is all arranged on the chassis, allowing it to carry up to 95 passengers, and adopts a full-channel low-floor design, which greatly improves the convenience and comfort of passengers.
epilogue
It can be said that BYD's new version of the B10 model is an effective verification of the implementation of the bus e-platform 3.0 technology, which has achieved a new breakthrough in the field of buses in terms of vehicle quality, driving experience, operational efficiency, and safety performance. BYD once again stood out from many projects and won the National Science and Technology Progress Award, which is inseparable from BYD's unremitting pursuit of technological innovation. The launch of bus e-platform 3.0 technology will surely boost the new passion for the development of new energy buses in the mainland.
