In the growing domestic new energy vehicle market, A-class BEV occupy the absolute main force, accounting for 36% of the new energy vehicle market in 2020. Reasonable body size and moderate price are one of the important factors that attract consumers' attention. At the same time, the core technology of the "three-electric system" and the actual performance of the cruising range also play a decisive factor when users purchase.
It is reported that Beijing Hyundai, together with Cheyun and E-Bang, held an open class "Enabling the Future"-Festa BEV "Power System" to jointly discuss topics related to the core technology of BEVs, and popularize BEV knowledge so that consumers can better choose products that suit them.
For ordinary consumers, the battery quality and performance of electric vehicles play a decisive role in everyday vehicles. The speed of charging and how far it can run with full power are the most important indicators. Power batteries have always been the core of industrial technology, and the types of technologies are also emerging in endlessly.
Take Beijing Hyundai Festa BEV supplier CATL as an example. Its products are represented by ternary lithium batteries, with a total power density of up to 200Wh/kg. Not only is it at the top level in the industry, but also has been tested by the market, with a good reputation and reliable quality. Festa BEV’s 490km NEDC cruising range can not only meet the actual needs of the car, but also take into account the cost, so that the price is within the range acceptable to consumers.
It is worth noting that, in terms of charging, thanks to the high-efficiency charging system adopted by Festa BEV, it can be charged for 100km in 12 minutes under low battery conditions, and it only takes 40 minutes to charge 30% to 80%.
At the same time, the safety issues of electric vehicles and the battery life and charging in winter are also concerned by consumers. In this regard, when the Festa BEV charging temperature is too low in winter, the system can preheat the battery to shorten the charging time. In summer, with the built-in temperature sensor, Festa BEV can cut off the charging in time when there is a safety hazard in charging, putting safety first.
In addition, in view of the fact that the actual endurance of the BEV is far from the operating conditions, the Festa BEV also uses the third-generation IEB energy recovery system developed by "own" Hyundai Mobis, and the power consumption per 100 kilometers is as low as 12.7kWh. , The actual electricity bill is about 6 yuan per 100 kilometers.
In terms of power, the technology adopted by the Festa BEV has a maximum power of 135kw, which is comparable to the power output performance of some 2.0T engines and meets the demand for power under daily working conditions.
