The cruising range exceeds 400 kilometers, and the air conditioner can be safely turned on in winter

July 11, 2020
(Reported by Xiawu Wuhan in this website): Dongfeng Group recently launched a new new energy car with a cruising range of more than 400 kilometers, and can safely turn on air conditioning in winter.

Since the birth of pure electric vehicles, mileage anxiety has been a topic that cannot be circumvented. The person in charge of Yixuan EV500 project of Dongfeng Technology Center introduced, "Yixuan EV500 model is equipped with eCMP platform battery system, the energy density of the battery pack reaches 140Wh/kg, and its battery management system has the ability to estimate the remaining battery energy and health status, which can be effective Improve the stability and reliability of the whole vehicle. The battery energy reaches 47.7kWh, ensuring a comprehensive cruising range of 400km.

While having excellent performance, Yixuan EV500 also meets the most stringent safety level. The battery system has IP67 and IPX9 waterproof ratings and has passed tests such as mechanical shock and seawater immersion. "Even under extreme operating conditions such as high temperature, wading, collision, etc., the battery assembly can still ensure safety, reaching the functional safety level ASIL D level (the highest level of vehicle safety integrity)."

A major anxiety for electric car users is that they dare not turn on the air conditioner in winter, and Yixuan EV500 uses a high-efficiency heat pump air conditioning system, which can greatly reduce energy consumption when heating in winter.

Test data shows that under the same operating conditions, compared with the previous air-conditioning system, the high-efficiency heat pump air-conditioning system used by Yixuan EV500 can save 1 to 2 kWh per hour and bring about a 20% increase in cruising range.

The general heat pump air-conditioning system can basically only work at an ambient temperature of minus 10 degrees Celsius, while the heat pump air-conditioning system of the Yixuan EV500 can function at a temperature of minus 18 degrees Celsius or lower, and the low-temperature use environment has a wider coverage.

In the interior, the new car will be equipped with a 7-inch LCD instrument + a 10.25-inch central control screen, and will be equipped with WindLink 4.0 Pro artificial intelligence vehicle system and L2 level auxiliary driving system. The specific configuration information has not been announced.

In terms of power, Yixuan EV500 is equipped with a permanent magnet synchronous motor with a maximum power of 120kW (163PS), a power battery capacity of 47.7kWh, and a cruising range of 400km under NEDC operating conditions.

Yixuan EV500 has officially started pre-sale, and the pre-sale price after subsidy is in the range of 145,800-15,500 yuan.

According to industry insiders, the cruising range of new energy vehicles is not as long as possible, because the battery is very heavy, and often accounts for about 20% to 30% of the entire vehicle weight.

Under the current technological conditions, the battery energy density cannot be increased on a large scale. After reaching a certain mileage, most of the increased battery capacity is used to transport the battery itself. And the larger the battery, the longer the charging time and the higher the price. For urban users, the 400-kilometer cruising range is economical and practical.
