GWi 90% for new energy vehicles in 2020

2070 China Automotive Industry Development (TEDA) International Forum held in Tianjin, more than 1,000 domestic and foreign industry elite in this heated debate hot topic.
Introduce the planning direction of new energy vehicles.
In the Guangzhou auto show in 2015 when the Geely Group officially released the next Turbocharger five years the new energy product strategy, is the blue Geely action, the goal is to 2020 when Geely 90% of the cars are new energy vehicles. To this
goal, Geely main technical route EV, PHEV and HEV, which is also consistent with the country to vigorously promote the line. We rely on Geely's existing 3.0 and the next new 4.0 modular modular architecture, vigorously promote the
implementation of the new energy strategy, our planning is plug-in and hybrid sales accounted for 65%, pure electricity Accounting for 35%. Geely wants to allow consumers to buy hybrid or plug-in hybrids at traditional car prices or
close to traditional car prices and achieve sales targets.
Next to the main three technical aspects, the first is the battery. New energy vehicles, especially the popularity of pure electric vehicles, we all know that the first is certainly the battery energy density and cost of the breakthrough
as a prerequisite. In the future for a long period of time a higher single mileage is our new energy product development process to pursue a very important indicator. Through the upgrading of the battery material system, continue to
enhance the updated energy density, without increasing the size of the battery pack and the weight of the premise can make our vehicle has a higher driving range. Compared with the traditional lithium battery, solid-state battery with
energy density, good security features, we expect that by 2028 when all solid-state battery technology can mature, can be carried in the vehicle above the application.
The following chart is mainly from our current application of flexible battery pack based on the estimated 10 years of battery development planning line, assuming that A and B-class pure electric vehicles, for example, we expect to 2021
Able to reach 600 kilometers of driving range, to 2028 is expected to reach 800 kilometers of driving range. In the modularization and platform of the battery, Geely new energy vehicle product planning is modular and platform for the
layout, large and medium-sized car with coilovers different architecture programs, such as we and Volvo jointly developed CMA platform architecture, will The whole system is equipped with new energy platform. Different vehicle sizes, different
body structures, including differences in demand for driving distance, the platform will greatly shorten the development cycle, saving development costs.
For example, we in the battery pack platform, inside the module and high-voltage electrical components and battery management system is fully platformable. With a similar shape of the battery pack we can achieve a different driving range
and energy management methods, you can ensure that the same architecture under the vehicle platform changes are minimal, but also can greatly save the development costs of the battery pack itself. Of course, this for the downstream
suppliers should also be a more economical program.
Below the left side of this figure shows the Geely PHEV battery system modular and universal program, is being implemented. For the battery pack of the lightweight, we cover the battery pack with a non-metallic materials, the next tray
with cast aluminum and aluminum materials to the king of luxury, for example, we changed the box after the aluminum box weight Reduced by 47%, the weight dropped from 76 to 40, in the AEDC under the conditions of Emperor Hao EV pure
electric driving range can reach three hundred kilometers, the battery pack weight loss effectively enhance the new generation of Emperor EV continued mileage, follow-up we will Have launched a higher continuous history mileage of pure
electric vehicles.
On the right side of the main embodiment of the battery pack and body integration program, the left is the battery pack installed directly on the threshold, the battery pack on the body for effective support, to enhance its anti-side
touch performance. There are many batteries in the middle and the seat connected to the battery pack and body connected to improve the vehicle's strength and stiffness.
On the right side of this figure, the body and chassis design takes full account of the battery pack and battery energy requirements, the battery pack is completely covered with the floor to maximize energy. For pneumatic systems, the
integrated technology of motors, reducers and inverters is the current mainstream development direction. It is expected that by 2021 the motor and point reducer, the development of the inverter will make our products more energy
efficient and environmentally friendly. With the output of the hub motor, the slowdown technology can matured to further reduce the size of the pneumatic part, thereby enhancing the vehicle power and driving range in the motor
controller, the application of wide band gap material will become the new inverter Step-by-step development focus direction.
New materials The application of new technologies to enhance the peak and continuous performance of the motor, it uses e46 m3 coilovers the future route we expect is the winding of the flat copper wire technology to reduce the noise to enhance the low-
speed torsional zone efficiency of the core stacking technology will be in the future Of large-scale application of the product. And with the silicon steel sheet material for further production applications, the motor power density will
be further enhanced. For example, now synchronous motor efficiency to 99%, our goal is 98%.
At the same time as the new cooling material for further application, the motor electric rotor effect will be further improved to improve the motor running capacity to increase the sustainable operation time, coupled with new materials
and new technology applications, the motor power density we expect from 3.2 kW / Raised to 5.5 kW / kg.
The following describes the control system, thanks to the current highly integrated structure design to further improve the power density further miniaturization, at the same time each module manufacturers to vigorously promote the new
material of silicon carbide power module development and verification, by the intelligence of the power The device can support higher switching frequency, further optimize the motor control performance, and compared to the current common
silicon power module before the silicon carbide material can greatly inhibit the module loss, probably at 30% so the new material material application will Its quality leap, while bringing the installation more simple, more reliable
products, system security will be further improved.
In addition, we are also concerned about the self-encapsulated power module, and now some manufacturers are also applied, some related performance has also been a preliminary recognition, we expect that by 2028 to 2030, 80% should use
independent packaging module The Next to introduce the charger-related, charging time is short, cost-effective, will become the major car prices and market pursuit of the goal. Car charger will also be planning for this high-voltage
junction box, CDC module charging and integration, and the future will gradually turn into deep integration, from the power, components and other aspects will greatly reduce costs. This year we have achieved in the Imperial EV 6.6
kilowatt high-voltage charger, the next two years the charging system will achieve more power car key machine to high-voltage junction box DCDC physical integration, the use of functional integration and power module reuse program, the
overall Efficiency and performance can be improved to further reduce development costs and direct costs of the product.
We expect to achieve in-vehicle charger, PDU, DCDC depth integrated charge power of 40 kWh or even higher by 2020 to 2025.
In the wireless charging technology we have done some work, wireless T3 turbo kit charging technology should soon be able to market-oriented, this technology and the combination of automatic driving to solve the problem of automatic parking charging
for users to show better convenience, wireless charging High-voltage alternating current completely wrapped in the charging device, no exposed high-pressure horn, and fundamentally solve the conduction charge of human safety hazards.
Wireless charging system and the transmitter and the absorption of the physical connection just right to circumvent the life of the charge and discharge problems, Geely in September 2016, the first successful debugging of the first
generation of wireless charging function, power up to 6.6 kilowatts, Industry well-known charging service providers to discuss the relevant industrial technology program, and in the discussion of industrial technology standards. Is
expected to be achieved by 2020, wireless charging of the production, to 2025 to achieve wireless charging technology and car charger integrated program, and put into mass production, when the wireless charging technology will become
mature, wireless charging power conversion module and the car The charger to achieve reuse to improve utilization.
I am also committed to Geely Automobile will soon provide users with a shorter charging time more convenient way to charge longer driving range of new energy vehicles, but in the field of wireless charging there are three more need to
pay attention to the problem.
One is the energy transmission equipment and receiving equipment between the precise positioning problem, which is our combination of parking technology to solve, there is the suppression and prevention of battery harassment, especially
for similar to the pacemaker harassment problem. The other is the efficiency of the collection and delivery, the current efficiency relative to our conduction charger efficiency is still far worse.
Simple to be summed up in the battery, from the energy density, life mileage increase, modular, general, lightweight, integrated is our technical line. In the motor is to improve the motor power density, improve vehicle control
efficiency, the charger is a multi-function controller integrated to improve the wireless charging technology, in order to enhance GT2871 turbocharger the performance of the three systems. Geely also in the industrial point of view in the global
introduction of sophisticated technical personnel, is committed to building our own new energy R & D team, shaping a comprehensive professional three electric technology talent echelon, to promote the core of the three systems
manufacturing program, Technical level of improvement, and always firmly with the idea of ​​creating excellent Chinese brands, unswervingly achieve the 2020 blue action goals, to fulfill our social responsibility and mission.
