Pure electric SUVs with a price of around 200,000 yuan are a "must be fought for by military strategists". They are particularly popular because of their liquid-cooling technology, which has great battery life and charging speed in the northern winter. These models represent the manufacturer's highest level of technology and craftsmanship. They have a good driving experience in terms of body size, comfort, performance, battery life and other conveniences, and their sales performance is naturally not bad.
Today I recommend 4 pure electric SUVs with liquid cooling technology, namely Beijing Hyundai Ensign EV, BYD Song Pro? EV, WM EX5, and Xpeng G3. They are Internet celebrities. , the quality itself is also good, and it has at least two sets of liquid cooling circulation systems, making it a useful tool for travel in the northern winter.
Term explanation
PTC heating system: PTC heating elements have traditional heating elements such as constant temperature heating, no open flame, high heat conversion rate, minimal influence on power supply voltage, and long natural life. With incomparable advantages, its application in electric heating appliances is increasingly favored by R&D engineers;
PTC heating system: through the PTC heating module, the circulating coolant is heated and pumped through electronic water The cockpit blower provides heating servo, and the power is generally 6-7 kilowatts;
Battery temperature control: through the PTC heating module, the circulating coolant is heated, and is sent to the power battery assembly through the electronic water pump , providing low-temperature heating and high-temperature refrigeration services for the battery cells to ensure the normal operating temperature of the battery (5℃-35℃), and the power is generally 3-5 kilowatts;
BAIC Hyundai? Encino EV< /p>
Price after subsidy: 172,800-198,800 yuan
Battery capacity: 64.2 kilowatt hours
Comprehensive range: 500 kilometers
100 kilometers of electricity Consumption: 13.8 degrees
Fast charging 30-80%: 0.5 hours
Heating system: 3 sets of circulation pipelines, 2 sets of PTC module servo.
Air conditioning: Electrically driven heater box type PTC module for servo cockpit air conditioning and heating system.
Battery: Angsino EV uses square NCM batteries provided by CATL, with an energy density of 146.6Wh/kg. Faced with the problem of limited battery power and sharp increase in power consumption at low temperatures in winter, Ensino EV can use PTC to heat the water circulation system with a power of 3kW, thereby ensuring that the battery is at normal operating temperature, extending battery life, and ensuring Charging time.
BYD Song Pro EV 500
Price after subsidy: 179,800-219,800 yuan
Battery capacity: 59.1/71 kWh
Comprehensive range: 405/502 kilometers
Power consumption per 100 kilometers: 13.4 degrees
Quick charge 30-80%: 0.5 hours
Heating system : 2 sets of circulation pipelines, 2 sets of PTC module servo.
Air conditioning: After the electric drive under the e platform is optimized to three-in-one, the cockpit air-conditioning and heating PTC power is reduced and the power consumption is smaller.
Battery: BYD’s battery cell is equipped with its own lithium nickel cobalt manganese oxide battery with an energy density of 160Wh/kg. The liquid cooling system delivers coolant to the inside of the battery pack through a variable flow electronic water pump to control the operating temperature of the battery cells between 5° and 35°. Power batteries with different capacities are equipped with PTC modules of different powers to accurately control the temperature range of low-temperature preheating (high-temperature heat dissipation).
Weima EX5
Price after subsidy: 139,800-189,800 yuan
Battery capacity: 52.56/69 degrees
Comprehensive battery life : 400/520 kilometers
Power consumption per 100 kilometers: 14.7 degrees
Quick charge 30-80%: 0.5/0.58 hours
Heating system: 2 sets Circulation pipeline, 1 set of PTC module servo, diesel engine heating.
Air conditioning: A dual-channel air conditioning and heating system that can use either PTC or diesel-heated air conditioning and heating. In the 2.0 system, electric heating only participates in work when it is above 0°C. Rely on diesel for heating below 0°C.
Battery: WM Motor's battery is a ternary lithium battery with NCM ratio. There are four suppliers: CATL, Zhejiang Gushen, Tianjin Lishen, and Suzhou Yuliang. The energy density is 170Wh/kg. about.
Its thermal management strategy is mainly intelligent and precise management of battery core temperature. Through independent liquid cooling design, PTC electric heating system, and minus 30°C polar heating system (diesel heating), it can be turned on independently in different temperature ranges. Heating and cooling functions realize constant temperature thermal management of battery packs.
Xpeng? G3
Price after subsidy: 143,800-196,800 yuan
Battery capacity: 50.5/66.5 kWh
Comprehensive Battery life: 401/502 kilometers
Power consumption per 100 kilometers: 13 degrees
Quick charge 30-80%: 0.5 hours
Heating system: 2 sets of cycles Pipeline, 2 sets of PTC module servo.
Air conditioning: PTC heating coolant, air conditioning? Another coolant expansion tank of Xiaopeng G3 belongs to the air conditioning heater system. Although the heat source of the heater still uses PTC components with high energy consumption, but first Heating the coolant and then transferring the heat into the car will make the body feel more comfortable and not too dry.
Battery: The 2020 Xpeng G3 uses NCM811 square batteries from CATL. The energy density of the battery system reaches a maximum of 180Wh/kg. The principle of PTC heating of the thermal management system battery pack is to first heat the antifreeze, and then transfer the heat to the battery core through the liquid cooling system to achieve a constant battery temperature. Compared with heating directly outside the battery module, this heating is more uniform and efficient.
Summary: The early technology of battery liquid cooling system may not be much better than air cooling technology, but with the advancement of technology, the advantages of electric vehicles with liquid cooling technology in the severe cold weather in the north are gradually revealed. I believe everyone has witnessed the miserable state of a very impressive car like the Roewe Marvel? From this perspective, we can see the importance of this liquid cooling technology to northern users, and what is determined by demand and market is the truth.
