nikkei bp dismantled the latest pure electric vehicle jikrypton 007 under geely automobile’s jikrypton brand, which had a great impact on the japanese automobile industry.

this car has mixed reputations in the country, but it has caused a lot of discussion in japan. nikkei bp analyzed the rear floor integrated aluminum die-casting technology, electric drive unit and battery structure of the jikrypton 007, demonstrating the car's technical advantages.

● four-wheel drive smart driving version configuration:equipped with lidar and two nvidia drive orin chips, it supports high-end autonomous driving functions.

● battery and battery life:equipped with a 75.6kwh lithium iron phosphate battery, the cruising range is 616 kilometers under cltc conditions.

● electric drive system:the front and rear wheels use a three-in-one electric drive axle system. the maximum output power of the rear motor is 310kw and the power of the front motor is 165kw.

01

jikrypton 007’s technological innovation:

die casting, batteries and electric drive systems

one of the core technical highlights of jikrypton 007 is that its body adopts a large-scale 7,000-ton integrated aluminum die-casting, which greatly simplifies the production process of the body and reduces the splicing parts of the body, thus improving the structural strength and reducing the cost. it reduces the weight of the vehicle body and also helps to improve the safety and driving performance of the vehicle.

● battery system and charging technology

the 75.6kwh lithium iron phosphate battery equipped with ji krypton 007 is also a major technical highlight of this model.lithium iron phosphate batteries are favored by the industry for their high safety, long cycle life and low cost. the 800v fast charging system can provide sufficient power to the vehicle in 15 minutes, ensuring a cruising range of up to 500 miles. kilometers or more.

● drive system

in terms of drive system, ji krypton 007 adopts a three-in-one electric drive axle system for the front and rear wheels.it integrates the drive motor, inverter and reducer, showing a high degree of integration and compact design. while improving the performance of the vehicle, it can also effectively reduce the weight and space occupation of the system and improve energy efficiency.

◎ the motor of the rear drive unit uses an embedded permanent magnet synchronous motor (ipmsm) with a maximum output power of 310kw, which can find a good balance between efficient power output and low energy consumption.

the silicon carbide (sic) inverter equipped with jikrypton 007 shows higher power density and efficiency. the introduction of silicon carbide power modules can reduce energy loss, improve the endurance of electric vehicles, and contribute to the lightweight design of the entire vehicle.

◎ the front drive unit uses an induction motor (im) with a maximum power of 165kw.

this hybrid drive mode (permanent magnet synchronous motor for rear drive and induction motor for front drive) not only improves the vehicle's dynamic performance, but also can achieve higher efficiency under different driving conditions. the reducer of ji krypton 007 is manufactured by a well-known zero produced by component supplier schaeffler, it further ensures the power transmission efficiency and reliability of the vehicle.

autonomous driving and smart cockpit:

nvidia drive orin and adas system

jikrypton 007 also shows strong technical advantages in intelligent driving technology. it is equipped with an autonomous driving computing platform driven by two nvidia drive orin chips.supporting intelligent driving functions, the completion of this system also allows ji krypton to continue planning forward.

jikrypton 007 is also equipped with lidar, 12 cameras, 5 millimeter wave radars and 12 ultrasonic sensors.it can provide drivers with comprehensive surrounding environment awareness and ensure the safety and reliability of vehicles in autonomous driving mode.

in terms of smart cockpit, ji krypton 007 introduces a unique display headlight design.this headlight contains 1,711 led beads, which not only provides excellent lighting effects, but can also display images and text through the lights to enable interaction with other vehicles or pedestrians.

this innovative design provides more user interaction possibilities for the automatic driving assistance system, further improving the technological sense and intelligence level of the vehicle.

the vehicle central control system integrates a head-up display (hud) and a vehicle-mounted display, providing drivers with a wealth of information display and control options, making the driving process more intelligent and convenient.

supplements for jikrypton intelligent driving:

the recent release of jikrypton 7x is also iterative on this basis.

◎ in terms of hardware configuration, the entire series comes standard with 31 smart driving sensing hardware such as dual orin-x chips and lidar. the aeb+ function can achieve safe braking at a speed of 120 kilometers per hour, and the sensing accuracy is higher than the industry average.

◎ in terms of parking function, it supports end-to-end intelligent parking in all scenarios, with the shortest parking time of only 23 seconds, and is suitable for various complex parking spaces.

◎ at the technical level, haohan intelligent driving 2.0's self-developed domain control and end-to-end architecture reduce the full-link response delay by more than 90%, and add more than 1,000 new traffic scene cognitions.

◎ in terms of experience, urban nzp can cope with complex intersection conditions and support complex intersections with up to 6 forks. the sudden braking rate is reduced by 90% during driving, acceleration and deceleration before and after traffic lights are smooth, mixed pedestrian and vehicle scenes are properly handled, and the overall driving experience is great. it is comparable to an experienced driver with 10 years of driving experience.

the urban nzp function of jikrypton 7x will be rolled out in batches across the country 2 months in advance. it does not require map data support and covers a wide range, from mohe in heilongjiang to the pamir plateau in xinjiang, whether in cities or rural areas, as long as there is navigation can drive.
