BYD has made frequent moves recently, not only bringing down the price, but also putting the configuration and technology up. For example, the Hiace 07EV, which debuted on May 10, not only has a people-friendly price of 189,800-239,800 yuan, so that many people have the confidence to challenge BYD's high-end all-round SUV, but also directly on the 5 world's first technologies.

The first is the world's first CTB vehicle safety architecture. I believe that people who pay attention to BYD must be no stranger to the integration of CTB battery body, but this time Hiace 07EV has been upgraded, the world's first endoskeleton CTB safety architecture, the 1500Mpa level ultra-high strength closed section rolling beam and blade battery integrated design, how to say, after the integration of a single beam, it is said to be able to bear the weight equivalent to 8 adult elephants.

In addition, although the e-platform 3.0 EVO is a safety architecture for the main and rear wheels, the front cabin safety buffer space of the Hiace 07EV has also been increased by 100mm, which is 32% higher than the previous one, and the frontal collision safety is improved by 60%. The safety architecture of the CTB vehicle adopts the steering front architecture, and the anti-deformation ability of the passenger compartment is increased by 50%. In addition, the steering gear front, a large amount of hot-stamping steel, a blade battery known for safety, 11 airbags are standard in the whole series, and driver monitoring assistance and other safety features bring all-round safety protection.

The second is the world's first 12-in-1 intelligent electric drive. The original power unit assembly was 8-in-1, and the Hiace 07EV has been upgraded to a 12-in-1, which integrates a 23,000rpm motor, a high-efficiency reducer, a silicon carbide electronically controlled (DC-DC) vehicle controller (VCU), a battery manager (BMC), a DC converter on-board charger (OBC), a power distribution module (PDU), an intelligent boost module, an intelligent uplift module, an intelligent self-heating module, and an intelligent energy management control system. In particular, the 23,000rpm motor is currently the world's highest-speed motor, with a top speed of more than 225km/h, which has a better acceleration experience and better endurance performance for daily travel.

The third is the world's first intelligent wide-temperature high-efficiency heat pump. The Hiace 07EV is equipped with a new generation of intelligent wide-temperature high-efficiency heat pump system, the industry's first intelligent dual-loop battery direct cooling and direct heating technology, and the world's first electric drive high-efficiency composite temperature control system, which realizes efficient temperature control and energy management of the passenger compartment, battery system and electric powertrain, and further improves the system efficiency of the vehicle, such as the 16-in-1 high-efficiency thermal management integrated module, which can reduce system loss by 20%;

The new generation of intelligent dual-circulation battery direct cooling and direct heating technology improves heat exchange performance by 20% and reduces battery thermal management energy consumption by 25%; The electric drive high-efficiency composite temperature control system increases the heat exchange efficiency by 40% and the low-temperature waste heat utilization rate by 30%, which increases the low-temperature cruising range of the vehicle by 45 kilometers and the driving range at room temperature by 60 kilometers, and greatly improves the performance of the vehicle under harsh working conditions such as high speed and climbing.

Fourth, the world's first global intelligent fast charging. The biggest pain point of new energy vehicles is charging, Hiace 07EV is equipped with the world's first intelligent upflow fast charging, full-scene intelligent pulse self-heating, intelligent terminal fast charging, intelligent boost fast charging four technologies, making full use of the existing public charging resources, to achieve an efficient travel mode that does not pick piles, does not pick the environment, and can also be fast charging in the northern winter.

For example, its intelligent upflow fast charging technology can give full play to the maximum capacity of 180kW (750V/250A) of the GB15 standard public DC charging pile in the existing charging network under any voltage platform, with a maximum charging power of 180kW and a maximum charging current of 400A, a charging time of 10-80% SOC less than 25min, a 30% increase in the utilization rate of public charging piles, and a shortening of the terminal charging time from 30 minutes to 18 minutes. In extremely low temperature environments, the charging time of the Hiace 07EV can be significantly shortened by 40%.

Fifth, the world's first intelligent motion control. Front double wishbones, rear five-link independent suspension, the entry is equipped with FSD frequency variable damping damper, these are the standard configuration of Hiace 07EV, 550 four-wheel drive intelligent aviation version is also equipped with Yunnan-C intelligent damping body control system, and provides iTAC intelligent torque control system, on the basis of greatly improving driving comfort and handling, and equipped with customized development of super iTAC multi-scene mode, including trapping assistant, terrain assistance mode, can match multi-scene travel needs.

All in all, while ensuring performance, Hiace 07EV has lower energy consumption, faster charging, safer and smarter, and a cheaper price, which is the power of domestic car involution and outward rolling.
