The success of BYD is indispensable to advanced battery development technology.
BYD Seal comes standard with the "super safe" " blade battery ", which benefits from the inherent advantages of the lithium iron phosphate battery material in terms of safety performance, and is fully used at high-risk safety points to provide the industry's only all-round safety Coating technology greatly improves the safety performance of batteries. The
"blade battery pack" improves space utilization by 50% compared to traditional structures. With the advantage of high volume energy density, large-capacity batteries can be arranged in a smaller space to achieve longer driving range.
The eight-in-one electric powertrain adopts a hairpin-type flat wire motor independently designed and manufactured by BYD, and uses ultra-thin and high-performance silicon steel sheet , which breaks through the problems in the flat wire motor winding industry. By optimizing the magnetic circuit design, the iron loss of the motor is reduced, the heat dissipation performance is greatly improved, the rated power of the motor is increased by 40%, and the maximum efficiency can reach 97.5%.
comes standard with a wide temperature range and high-efficiency heat pump system. It uses refrigerant direct cooling and direct heating technology to achieve efficient regulation of the battery pack temperature. Compared with the traditional PTC heating device, the heat pump system has faster temperature control speed, and the driving range in winter can be increased by 20 %.
In extremely low-temperature environments, the system will generate additional heat energy in multiple modes through intelligent control of the electric drive assembly to meet the needs of the heat pump system. Even in extreme weather environments of -40°C, Seal's heat pump system still It can start normally and reduce the loss of heating energy consumption.
Due to the highly integrated system, the two modes of motor charging and driving are reused. During the charging process, Seal reduces the heat generated by the charging and distribution assembly, making the performance more reliable. The high-voltage electric drive boost charging solution can make full use of the national standard current limit of charging piles to achieve wide-area constant power charging. The full charging time is significantly better than the industry's high-power charging system, and it can charge in 15 minutes and travel 300km.
Summary:
The biggest problems faced by new energy vehicles are often the efficiency of the battery and the adverse effects of extreme weather on the battery. BYD can gain a good reputation, and it is undeniable that the battery plays an indispensable role. If you want to become a leader in the new energy field, you must develop advanced battery technology. This is worth learning from many new energy vehicle brands.
