As we all know, the core technology of BYD e platform 3.0 is mainly eight-in-one electric drive assembly and heat pump air conditioner, but unfortunately, BYD Seagull based on e platform 3.0 has neither heat pump air conditioner nor eight-in-one electric drive assembly.
The main reason for this situation is that the size of the Seagull is too small, and the heat pump air conditioner and the 8-in-1 electric drive assembly cannot be accommodated at all. In addition, the low manufacturing cost also has certain restrictions on the vehicle configuration.
By observing the body of BYD Seagull, it can be seen that in order to squeeze the space utilization rate to the extreme, the four wheels of Seagull are basically set at the edges of the four corners of the body, and the actual space in the front cabin is actually very limited. An electric drive is known for being highly integrated, and it is difficult to put it in, let alone a heat pump air conditioner.
Without the heat pump air conditioner, the cost and pricing of Seagull will be more affordable. After all, the cost of BYD heat pump air conditioner is still relatively high. This technology was only used in Tang, Han and other flagship models before, and it has only been decentralized in recent years. Entry model.
What is the difference between a tram without a heat pump and air conditioner?
Trams without heat pump air conditioners have a lower battery life achievement rate in low temperature environments than trams with heat pump air conditioners. Compared with ordinary air conditioners, the biggest advantage of BYD heat pump air conditioners is that the energy consumption of air conditioners can be reduced by about 40% at low temperatures, which in turn greatly improves the achievement rate of battery life at low temperatures. For example, BYD Han EV became the pure electric vehicle with the highest battery life achievement rate at that time by virtue of the heat pump air conditioner in the winter endurance test of an automotive media.
In addition, comparing the Han EV without heat pump air conditioner with the Han EV with heat pump air conditioner, in the environment of minus 6-7 ℃, the heating air conditioner is turned on for a full night, and the Han EV without heat pump air conditioner consumes 5 kilowatt-hours of electricity. Another Han EV with a heat pump air conditioner consumed about 3 kilowatt-hours of electricity, and energy consumption was indeed saved by 40%.
Although it is true that trams with heat pump air conditioners consume less energy than trams without heat pump air conditioners, it is difficult for Seagull, a small tram with very low power consumption, to show the energy consumption advantages of heat pump air conditioners, let alone Seagulls. Can't fit in a heat pump air conditioner.
