Generally speaking, this new BYD Song PLUSEV is a household pure electric SUV with a very precise positioning. From the driver's perspective, there is not much room for play in the sense of handling. The overall adjustment of the vehicle is relatively soft, including the brake system, steering assist system, power recovery system, etc., all of which start from a relatively pure "driver" perspective, and from the perspective of the passenger, it is relatively happy. After the body size of the BYD Song PLUSEV has been upgraded, the interior space is quite large, the three rear seats are very spacious, the floor is also flat, the waist and back support of the front and rear seats are also very good, and the riding experience is very comfortable.
As a home-style pure electric SUV, in fact, when considering the driving experience and configuration, the most concerned thing is the battery safety and battery life. At least it needs to satisfy the family's travel around the city without having to worry about battery life all day.
3. blade battery establishes core advantages
Electric car 's "flammable and explosive" has made many people discouraged electric cars. So, why does the blade battery of BYD make electric cars safer?
First of all, let’s look at the structure of the blade battery. Basically, the blade battery is actually lithium iron phosphate battery . The chemical composition structure of lithium iron phosphate batteries is more stable than that of ternary lithium batteries. From BYD’s “needle puncture experiment”, it can be seen that after the steel needle penetrates the ternary lithium battery, the ternary lithium battery almost instantly produces thermal runaway, and then explodes. The BYD blade battery is completely opposite. When the steel needle penetrates the blade battery Later, the performance of BYD blade batteries can be regarded as "no change in color". The reason is that when the steel needle penetrates the first stage of the diaphragm, the diaphragm will shrink and wrap the steel needle, preventing the circulation of electrolyte and electrons, so that there will be no further thermal runaway reaction. After the ternary lithium battery is punctured, due to the different chemical composition, a large amount of oxygen will be released in the first stage of thermal runaway, so that the diaphragm will dissolve instantly at high temperature and directly enter the second stage of thermal runaway, which will be out of control.
