It can be used, but the price/performance ratio is too low and the security risks are relatively high.
The production cost of lithium batteries is high, production equipment is expensive, and labor costs account for about 40% of production costs. The price is about three times that of lead-acid batteries. The value for money brought by three times the price is not high, and it looks flashy. Additionally, the lithium battery is not recyclable. If it is used, you can only throw it away or find a place to bury it.
The most important problem is that lithium batteries pose fire and explosion hazards. In electric vehicles, the sealing conditions are not very good, and it is easy for humidity to cause poor contact, among other reasons. may cause safety risks. However, technical performances lithium batteries are constantly improving, and high safety materials are also used.
According to incomplete statistics, as of August this year, more than 30 incidents of spontaneous combustion of electric vehicles have occurred in China, and most of the vehicles are equipped with ternary lithium-ion batteries . This proves that in terms of safety, ternary lithium-ion batteries are indeed inferior to lithium iron phosphate batteries. It is only because of their higher energy density that they have become the market mainstream.
However, technology continues to advance, and now many lithium iron phosphate versions of pure electric vehicles can compete with ternary lithium-ion versions in battery life, such as models following. If you want to buy a purely electric car that is safe enough and has a range toBefore meeting your daily needs, you can consider them.
BYD Han EV price after subsidies: 229,800-279,500 Full cruising range: 550/605 km
BYD Han is the latest medium and large sedan launched by BYD Auto, with a plug-in hybrid version Two versions (DM) and purely electric (EV) were officially launched in July this year. The Han EV is priced at 229,800 to 279,500 yuan after subsidies.
Compared with the DM version, the Han EV adopts a new family style design exclusive to BYD's pure electric models, and the overall appearance is refined and simple. In addition, the length of Han EV is also 20mm longer than that of the DM version, and the rest of the dimensional parameters are the same.
In terms of power, Han EV is equipped with the latest blade battery developed by BYD (lithium iron phosphate battery). The ultra-long-range front-wheel drive version has a cruising rangeNEDC era of 605 km. The high-performance four-wheel drive version has an NEDC cruising range of 605 km. According to the car buyer's actual test, the actual driving range of Han EV is not much different from the official marking and can meet the needs of daily commuting.
BYD Song PLUS EV launch time: September Full cruising range: 405/505 km
As a new compact SUV under BYD, the Song is positioned higher than this that the Song Pro PLUS will offer consumers with both gasoline and purely electric versions. The purely electric version, Song PLUS EV, adopts a front design similar to that of the Han EV, which is simple and elegant overall.
In terms of size, the length, width and height of Song PLUS EV are 4705/1890/1680mm respectively, and the wheelbase is 2765mm, which is the same as the gasoline version.The dimensions are exactly the same, which is different froms two Han versions. In terms of power, Song PLUS EV is equipped with BYD's third-generation permanent magnet synchronous drive motor, but the tuning is different, the maximum power is 163 horsepower and 184 horsepower respectively.
In terms of battery life, Song PLUS EV is equipped with a lithium iron phosphate battery, with a NEDC mileage of 405 km and 505 km respectively. It is reported that the car will start pre-sale on August 28 and will be officially launched in September. Interested friends can pay attention to it.
Model? 3 lithium iron phosphate version full range: 468 km
Some time ago, a set of Tesla lithium iron phosphate version model? 3 standard scope information appeared in the Ministry of Industry and Information Technology among. Information shows that the NEDC cruising range of the lithium iron phosphate Model 3 version is 468 km and qThe energy density of the battery system is 125 Wh/kg. In addition, the curb weight of the new car reaches 1,745 kg, which is 131 kg more than the current model of 1,614 kg.
It is reported that the car's lithium iron phosphate battery is supplied by CATL and its cost will be lower than that of the ternary lithium ion battery, which may further lower the price of iron model 3 lithium battery. phosphated version. If this is the case, then the Tesla Model 3 will definitely usher in a new wave of mad rush.
Full cruising range of Roewe Ei5 lithium iron phosphate version: 416 km
Not long ago, detailed information about Roewe Ei5 lithium iron phosphate version is appeared in the 7th batch of "New Energy Vehicles" issued by the Ministry of Industry and Information Technology in 2020. Catalog of models recommended for promotion and application. The length, theThe width and height of the new car are 4,544/1,818/1,521 (1,543) mm respectively and the curb weight is 1,560 kg, which is slightly heavier than the current model at 1,555 kg. This should be due to battery replacement. pack.
In terms of power, the Roewe Ei5 lithium iron phosphate version is equipped with a permanent magnet synchronous motor with a maximum power of 120 kW and a maximum torque of 255 N·m. Power settings are much higher than the. current model. In addition, the new car's battery has also been replaced with a lithium iron phosphate battery. The NEDC cruising range is 416 km, which is only 4 km different from the current model of 420 km.
It is worth mentioning that the Roewe Ei5 battery swap version also appeared in the Ministry of Industry and Information Technology recently. The battery used is also a lithium iron phos batteryphate. launched on the online carpooling market.
Price of Tang EV 2021 after subsidies: 279,500-314,800 Full cruising range: 505/565 km
On August 16, Tang EV 2021 was officially launched, and only two models of the 2021 Tang EV have been officially launched. A new car has been launched. Both models are priced at RMB 279,500 and RMB 314,800 after subsidies. Compared with the old model, the appearance of the 2021 Tang EV has remained basically unchanged, but the interior texture has been significantly improved, and it is equipped with the DiLink 3.0 system.
In terms of size, the new car remains the same as the old model. The length, width and height are still 4,870/1,950/1,725 mm and the wheelbase is 2,820 mm. However, new car battery has been replaced with BYD blade battery (lithium iron phosphate battery). The NEDC cruising range is 565 km and 505 km (four-wheel drive), thiswhich is higher than the old model equipped with ternary lithium-ion battery.
The above cars are the new cars on the market/to be launched which have long battery life and are equipped with lithium iron phosphate batteries recommended by car buyers. It can be seen that although it is equipped with a lithium iron phosphate battery, the range of the new car is not inferior to that of the previous versions with ternary lithium battery, such as BYD Tang EV. Therefore, considering safety, it is no longer a problem to choose a purely electric model of the lithium iron phosphate version.
