High safety and long service life, and the hybrid special blade battery meets BYD's acupuncture standard.
What is DM-i super hybrid? Mainly electricity? Hybrid power technology, to be precise, is an electric hybrid architecture with high-power motor drive and high-capacity power battery as the main energy supply and engine as the auxiliary. Mainly oil? The traditional hybrid technology is very different. In terms of battery capacity, the DM-i super hybrid can be equipped with a battery pack of 8.3 to 2 1.5 kWh, providing a pure electric cruising range of 5 1 to 120 km.
With electricity as the mainstay, the safety of power batteries is becoming more and more important. DM-i super hybrid special blade battery adopts lithium ferrous phosphate cathode material with inherent safety advantages, and lithium ferrous phosphate has good thermal stability and robust blade structure design, which makes it successfully pass various rigorous safety tests such as acupuncture test.
From the inside out, DM-i super hybrid special blade battery is sealed twice, which makes the overall safety further. The special blade battery adopts series battery technology, that is, the blade battery is formed by connecting a plurality of wound batteries in series, the wound batteries are packaged in soft aluminum to form a primary seal, and the blade batteries are packaged in hard aluminum shell to form a secondary seal, which greatly improves the safety level.
Series battery technology is unique to BYD in the world, with as many as 36 national patents. The traditional battery pack has nearly 100 energy-saving cores, while the battery pack with blade batteries in series has only a dozen energy-saving cores, and the number of parts is reduced by more than 35%, further improving the volume utilization rate; The power consumption of a single section reaches 1.53 degrees, and the voltage of a single section is above 20V, which lays the foundation for high-power charging and discharging.
Frequent high-power charging and discharging of power battery is a great challenge to battery life. The very stable crystal structure and advanced thermal management system of lithium ferrous phosphate ensure the long service life of special blade batteries.
Large capacity, long battery life and special blade battery help to realize more electricity and less oil.
Besides high safety and long life, high-capacity special blade battery can also generate electricity? Reservoir? The role of. The capacity of traditional hybrid battery is only about 1 kWh, and it can only be dispatched in the range of 0.5 kWh. The minimum battery capacity of the special power blade for DM-i super hybrid is 8.3 kWh, which can be dispatched at least in the range of 4 kWh, and can fully store the series power generation and energy recovery of the system. Even in the case of insufficient power, it can realize more than 80% electric drive, and the proportion of electric drive is close to 100% in urban conditions.
The large-capacity special blade battery effectively reduces the power loss and helps the DM-i super hybrid to achieve more electricity, less oil and efficient oil use, which is a solid backing for the ultra-low fuel consumption of the DM-i super hybrid. From the product performance point of view, the fuel consumption of Qin PLUS DM-i is only 3.8L per 100 kilometers, even lower according to media calculations, and the comprehensive cruising range can reach 1.245 kilometers, which is not only suitable for daily commuting in first-and second-tier cities, but also saves money and worry when running long-distance and high-speed.
In addition, the charging power of special blade battery is twice that of ordinary hybrid battery, and its internal resistance is lower. The charging and discharging efficiency is better than that of the traditional hybrid battery 10%, which can comprehensively improve the braking energy recovery rate by 30%. Many PHEV do not have DC fast charging and cannot be charged in DC charging piles; DM-i super hybrid provides two charging modes: AC slow charging and DC fast charging. High-power DC fast charging is suitable for national public charging piles, allowing users to use pure electric mode more actively.
Dedicated blade battery? Self-heating, not afraid of cold in winter? Its bright spot is also commendable, and its pulse self-heating and refrigerant direct cooling heating management technology is leading the world, realizing all-weather use scenarios. Pulse self-heating technology is the first in the world, which can raise the battery temperature through high-frequency charging and discharging. The temperature uniformity of the battery itself is better, and it can also be used in the cold northeast.
The special blade battery has high safety, long service life, large capacity, long battery life, fast DC charging and no fear of cold winter, which brings strong competitiveness to DM-i super hybrid and three mass-produced new cars, and will also provide strong power for new energy vehicles to accelerate the replacement of traditional fuel vehicles.
