In the cold winter, it is not only people who are afraid of the cold, but also electric vehicles. How to make electric vehicles "cold resistant"? And how to make electric vehicles perform better? As the pioneering work of Nezha Automobile's "Shanhai Platform", Nezha S is equipped with the most integrated heat pump system in the industry, with the energy efficiency ratio of the heat pump being as high as COP 2.0 and the winter endurance increasing by 20%. In the -20 °C environment, 10 minutes after turning on the air conditioner, the comfortable temperature can be reached in the car.
China's first vehicle system-level intelligent thermal management strategy: 20% increase in winter battery life, energy efficiency ratio cop up to 2.0.
Traditional thermal management mostly adopts a split management strategy, air conditioning, batteries, cockpit and other thermal management "separate", heating pipes are complex, but also easy to cause heat waste, collaborative inefficiency. Different from the traditional split vehicle thermal management strategy, HozonEPT4.0 constant temperature heat management system is an integrated thermal management system based on a highly integrated water source heat pump, which can integrate independent systems and unified management to minimize heat waste, minimize the consumption of battery power by the thermal management system, and ensure vehicle mileage.
On the one hand, the HozonEPT4.0 constant temperature thermal management system realizes the centralized management of the crew compartment, battery, electric drive and electronic components through the "brain" of vehicle heat management, and protects the performance and safety of the car. At the same time, the integrated design concentrates the physical parts of all components and the control parts of the components, so as to reduce the number of pipelines by 40%, increase reliability by 50%, and reduce the working temperature of the heat pump from the industry's -10 °C to -18 °C under the premise of meeting the comfort, and with the intelligent/self-selected efficient thermal insulation function to help Nezha S's winter endurance increase by 20%.
On the other hand, The HozonEPT4.0 constant temperature heat management system is equipped with the industry's most integrated heat pump system, using a minimalist integrated water source heat pump system, using a nine-way valve to combine 16 different working modes, automatically planning the heating degree of the heat pump system according to the ambient temperature and battery temperature, and enabling different heating modes. In other words, from the flow control valve and water pump to the air conditioning compressor and the cooling fan on the front-end cooling module, it can achieve fine control to ensure that the battery, air conditioner, and electric drive work at the most suitable temperature. In addition, the HozonEPT4.0 thermostatic thermal management system also recovers the waste heat generated throughout the cycle to maximize energy utilization. Nine-way valve support, multi-heat source management, efficient heat exchange, help Nezha S's thermal management efficiency COP up to 2.0, in the industry's top level.

-18°C ultra-low temperature heat pump working range, energy efficiency increased by 50%
Different from the traditional thermal management system heating energy consumption is high, affecting the endurance, the traditional heat pump system below -10 °C can not start, the heating effect is poor, HozonEPT4.0 constant temperature heat management system through electric drive waste heat recovery to achieve intelligent collaborative control of various components of thermal management, the overall energy efficiency is optimal. Even in the outdoor ambient temperature of -18 °C, the outlet air temperature can reach 48 °C, the energy efficiency is increased by 50%, and a single heat pump can meet the heating requirements of the passenger compartment. It is worth mentioning that Nezha S is equipped with intelligent dual-zone air conditioning, which can automatically calculate the wind direction adjustment mode according to the ambient temperature, electric drive temperature and temperature difference with the target temperature, and in the process of driving at -20 °C and 40km/h, it can be improved to a comfortable level in 10 minutes. While Nezha S gets rid of the "lack of heating" in winter, it will bring users a safer, smarter and warmer winter travel experience.
Increased battery temperature control, 15 °C-45 °C constant temperature accounted for 95%
While ensuring the maximum energy efficiency of vehicle thermal management, Nezha Automobile's independently developed HozonEPT4.0 constant temperature heat management system is a set of forward-looking battery management technology, which has the characteristics of high energy, high endurance, high safety, high stability, etc., with low temperature insulation, high temperature cooling and driving temperature constant temperature and other functions, which can effectively inhibit fast charging temperature rise and improve low temperature driving endurance and dynamics. Among them, the thermal management system actively heats and cools, quickly improves the low-temperature charging efficiency, and saves about 2% in a single charge; intelligent driving heating helps increase the winter endurance by about 4%; with the intelligent/self-selected efficient heat preservation function, the battery system 15 °C-45 °C constant temperature accounts for 95%. In other words, whether it is in the hot Turpan or in the cold desert river, Nezha car can ensure the efficient stability and safety of the battery, so that there is no "forbidden area" for new energy vehicles.
【Nezha S】
The HozonEPT4.0 constant temperature thermal management system equipped with Nezha S can achieve higher thermal management efficiency at a lower cost, bringing consumers a smarter, safer and more comfortable vehicle management and travel experience, which is the most perfect interpretation of Nezha Automobile's "science and technology equality" values. As the first B-class digital electric coupe based on the "Shanhai Platform", Nezha S will also become the vanguard of Nezha Automobile to enter the high-end market, and boost Nezha Automobile to embark on a new journey of the brand.
