Electric cars with a range of 500 kilometers are now everywhere, but have you ever seen an electric bicycle with a range of 500 kilometers?
The H5 third-generation voyage version launched immediately, a charge can last 500 kilometers, the price is 7999 yuan, even if it is six discounts, you can still run 300 kilometers, which is too strong for an electric bicycle, think about it, the takeaway brother often needs to change a few batteries a day, and change to this car, you don't need to change the battery for a day.
The reason why the H5 third-generation voyage electric vehicle can run so far is mainly because it is equipped with a BYD automotive-grade power battery, the battery capacity is 46V120Ah, and the BYD lithium iron phosphate blade battery is used, the battery is used more than 2000 times, and it can achieve a 5-year warranty.
In fact, in addition to Lima, BYD has also signed a strategic cooperation agreement with Xinri Electric Vehicle, which also means that BYD's blade battery will be used more in electric bicycles in the future, and this will further improve the battery life of electric bicycles, and there may be many electric bicycles with a range of more than 100 kilometers in the future.
In fact, in addition to the improvement of the battery life of the electric bicycle, the more important thing is the improvement of safety. According to the statistics of the National Fire and Rescue Administration, a total of 21,000 electric two-wheeler fires were reported nationwide in 2023, an increase of 17.4% compared with 2022, and 18,000 electric two-wheeler fires were reported nationwide in 2022, an increase of 23.4% compared with 2021.
The tragedy of spontaneous combustion of electric bicycles in Nanjing, resulting in 15 people killed and 44 people being hospitalized, is still vivid. For electric bicycles, the culprit of spontaneous combustion, most of them are lithium batteries, data over the years, the probability of fire of lead-acid batteries is 1 in 100,000, the new national standard weight limit after the promotion of lithium batteries, the number of fires in 250 million lead-acid battery electric vehicles 2500, 50 million lithium battery electric vehicle maintenance 8500 fires.
Why lithium batteries have become the standard configuration of high-end electric bicycles? The main thing is the energy density, the lead-acid battery is safe, but the energy density is too low, and the battery life is too high, and the lithium battery has a high energy density, but the problem is that the safety is poor, especially the equivalent of the car, the lithium battery of the electric vehicle has a lower cost and lower technical content, so the thermal stability is worse.
And electric bicycles are mixed, many lithium batteries are actually scrapped by electric vehicles on the ladder, which is an old battery, and the safety performance is worrying, and BYD's lithium iron phosphate battery can just solve this problem, its energy density is much higher than that of lead-acid batteries, slightly lower than ternary lithium batteries, but it is enough.
The blade battery balances the structural strength, thermal management system and module-free packaging technology of the power distribution system, and after the acupuncture test, there is no open flame and smoke, and the temperature of the battery surface is only about 30-60°C. In addition, in terms of cost, it is slightly lower than ternary lithium batteries, so blade batteries are indeed suitable as power batteries for electric vehicles.
On February 25 this year, BYD Fodi Battery officially issued a document announcing that based on the "2.23" fire accident in Nanjing, the battery management team and development team "held an emergency meeting overnight" to discuss the quality and safety solutions for two-wheeled vehicles, and decided to apply the research and development results of passenger cars to the field of two-wheeled vehicles, increase R&D investment in two-wheeled vehicles, and develop a safe battery that can go upstairs.
Fodi Battery also said that it will cooperate with all parties and participate in the improvement of industry policies and regulations to prevent the recurrence of such social problems and truly implement the mission of "allowing people to use batteries without worry".
Therefore, BYD's entry into the field of electric bicycles can undoubtedly be regarded as a dimensionality reduction blow, after all, the safety of new energy vehicles, compared with two-wheeled electric vehicles must be much stronger, we also hope that blade batteries can appear more on electric bicycles, so that similar tragedies will not happen again.
