After watching the launch conference of Hiace 07EV, the first feeling: BYD Ocean Network is about to usher in a new round of sales explosion.
In the Hiace 07EV, you can clearly see BYD's significant progress in the definition of new car products -
The interior and exterior design is more simple and advanced, and it is almost impossible to find the abstract and complex elements that appeared from time to time in BYD products in the past.
With a length of 4830mm and a wheelbase length of 2930mm, the vehicle has plenty of volume and cabin space.
The high-end version of the intelligent cockpit - DiLink 100 and the high-end intelligent driving assistance system of the Eye of the Gods - DiPilot are on the car, ensuring the mainstream intelligent cabin and intelligent driving experience, and the Hiace 07EV also realizes up to 100 configurations of the whole series as standard.
With a starting price of 189,800 yuan, many selling points of the Hiace 07EV point to one goal: to reshape the value benchmark of the all-round technology mid-size pure electric SUV.
The addition of the Evo suffix not only symbolizes the re-evolution of BYD's pure electric system capabilities, but also an important support point to define the technological competition in the second half of the new energy vehicle.
"High integration" has once again become the key word of the e-platform 3.0 Evo, which is composed of five technology clusters, covering five dimensions: vehicle safety, electric drive, thermal management, charging and energy replenishment, and motion control.
● CTB Vehicle Safety Architecture Technology Cluster
● 12-in-1 intelligent electric drive technology cluster
● Intelligent wide-temperature high-efficiency heat pump technology cluster
● Global intelligent fast charging technology cluster
● Intelligent motion control technology cluster
Under the premise of "safety is the greatest luxury", the CTB vehicle safety architecture of Hiace 07EV adopts the main rear-wheel drive safety power architecture, and adopts the steering front architecture, and the steering gear does not interrupt or encroach on the safety force transmission structure, making the power transmission more smooth and coherent.

At the same time, the new car uses a high-strength design solution based on the e-platform 3.0 Evo, called "endoskeleton CTB safety architecture", which further deepens the integrated safety design of the battery and the body, so that the blade battery and the body together form the internal skeleton of the passenger compartment, and at the bottom of the passenger compartment, a honeycomb-like high-rigidity battery pack that can withstand the crushing of a 50-ton heavy truck is used as the floor of the passenger compartment to build a safety foundation for the passenger compartment.
At the front of the passenger compartment, the new architecture introduces the integrated design of TRB integrated dash panel and blade battery for the first time, so that the front of the passenger compartment has strong protection capabilities. For the first time, the side of the passenger compartment integrates the 1500Mpa ultra-high-strength closed-section rolled beam with the blade battery, and after a set of operations, the regional body strength of the Hiace 07EV is increased by more than 60% compared with the industry.
With a safe and sturdy body, the vehicle's driving ability and handling are also improved. In addition to the front double wishbone + rear five-link independent suspension, which is equipped with FSD frequency variable damping damper at the entry, the Hiace 07EV 550 four-wheel drive intelligent aviation version is also equipped with the Yunlin-C intelligent damping body control system, and provides iTAC intelligent torque control system, and will also be equipped with the custom-developed super iTAC multi-scene mode.
As for the electric drive and charging energy supplement that users are most concerned about, Hiace 07EV adopts a 12-in-1 intelligent electric drive system, which integrates 23000rpm motor (maximum speed in mass production), high-efficiency reducer, silicon carbide electronic control, vehicle controller (VCU), battery manager (BMC), DC converter (DC-DC), on-board charger (OBC), power distribution module (PDU), intelligent boost module, intelligent upflow module, intelligent self-heating module, and energy management intelligent control system. Not only is the structure more compact, but the energy conversion efficiency of the whole vehicle is also higher.

In particular, with the support of the "tandem laser welding silicon carbide power module", the stray inductance can be greatly reduced by 75%, the maximum efficiency of the electronic control can reach 99.86%, and the overcurrent capacity is increased by 10%, achieving a comprehensive leap in the performance of the silicon carbide power module.
The data reflected in the daily use of the car is: CLTC comprehensive efficiency of 92%, medium and low-speed urban efficiency increased by 7%, cruising range increased by more than 50km, which is very obvious for urban users, the extra 50km, basically means that the vehicle can cover one more working day of commuting and round-trip.
In the dimension of charging and energy supplement, it further reflects BYD's thinking that the interests of users are supreme, and unlike other car companies that advertise the charging time and the ultra-high power of self-built piles when releasing new cars, BYD has long realized that the real problem faced by the vast majority of users is -
◆ There are many models of 800V platform, but public charging piles are still dominated by low-voltage piles;
◆ The charging speed of 20%-80% is very volatile, but when it comes to 80%-100% of the charging time at the end of the SOC, it is all about him;
◆ How much time will be added to charging the vehicle in a low temperature environment in winter?
To this end, the e-platform 3.0 EVO global intelligent fast charging technology cluster has come up with four major technologies: intelligent upflow fast charging, full-scene intelligent pulse self-heating, intelligent terminal fast charging, and intelligent boost fast charging, whether it is public DC or public supercharging pile, so that Hiace 07EV can achieve high-power charging. Among them, the intelligent upflow fast charging technology can decouple the charging voltage from the vehicle voltage, and the maximum capacity of the GB15 standard public DC charging pile of 180kW (750V/250A) in the existing charging network can be fully exerted under any voltage platform. This technology realizes high-power charging under the specification of 250A charging port.

The intuitive performance is that in the case of using the GB15 standard public DC charging pile, the maximum charging power of the 550 model of the Hiace 07EV entry version can reach 180kW, the maximum charging current can reach 400A, and the charging time of 10-80% SOC is less than 25min; The 610 long-range version, 610 intelligent aviation version, and 550 four-wheel drive intelligent aviation version can reach a maximum charging power of 240kW on public supercharging piles.
At the same time, the Hiace 07EV 10-80% SOC has a charging time of up to 25 minutes, and the terminal charging time has been reduced from 30 minutes to 18 minutes. In extremely low temperature environments, the charging time of Hiace 07EV can be significantly shortened by 40%.
Advances in thermal management are also helping battery life, and the e-platform 3.0 Evo gives a 16-in-1 high-efficiency thermal management integrated module, which is terrifying compared to the mainstream 8-in-1. At the same time, the Hiace 07EV is equipped with intelligent dual-circulation battery direct cooling and direct heating technology and electric drive high-efficiency composite temperature control system as standard, 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, with the low temperature cruising range of the vehicle being increased by 45km and the normal temperature driving range by 60km.

Brief summary:
Throughout the release of the entire e-platform 3.0 Evo and Hiace 07EV, BYD has maintained the characteristics of "technology changes the experience" as always, without fancy golden sentences, without leading under various definitions, but returning to the core scene, attaching importance to real experience, revealing the true background of the competition in the second half of intelligence. Numerous and other breakthrough technologies, coupled with the mainstream model size and configuration level, also allow Hiace 07EV to strengthen the layout of Ocean Network in the mid-size SUV market segment, and build a new way of full-scene intelligent electric travel for the new generation of urban users.
