BYD Automotive IGBT Module
IGBT is the core of the electric vehicle control system and determines the energy efficiency of the vehicle. As early as 2008, BYD established a semiconductor company in Ningbo. The IGBT chips developed by it are widely used in various electric vehicles, breaking the foreign high-end IGBT technology. Blockade. As a vehicle company that masters the core technology of 'SanDian', BYD has been promoting the development of China's new energy automotive industry with high technology, and its pure electric passenger car with IGBT 'China Core' has achieved large-scale application worldwide.
Breaking the 'China Core' of the International Technology Blockade New Energy Vehicle Drive System
IGBT (Insulated Gate Bipolar Transistor) is a compound fully-controlled voltage-driven power semiconductor device. It is a representative product of the world's third technical revolution in power electronics. It has high frequency, high voltage, high current, and easy to switch. Its excellent performance is praised by the industry as the 'CPU' of power converters. As a integrator of many high-tech technologies, IGBTs have been widely used in electric vehicles, industrial inverter control, locomotive traction, and consumer electronics. However, China's IGBT market has been monopolized by foreign manufacturers, especially its core technology - the design and manufacture of IGBT chips.
In response to the automotive IGBT design and manufacturing challenges, BYD broke through key technologies such as automotive-level IGBT wafer design, module cooling, packaging technology and manufacturing, and realized the industrialization of automotive-grade IGBT power modules, breaking the foreign patent and technology blockade, and First-in-one motor drive and vehicle-mounted charge-discharge multiplexing IGBT fusion design technology.
Bidirectional inverter charge and discharge type motor controller
BYD took the lead in implementing the batch application of autonomous IGBT chips on the new energy vehicle electric drive system, which has explored an effective path for the full localization of the new energy vehicle electric drive system. After years of full validation, BYD's IGBT has been fully applied to new energy sources. In the electric drive system of passenger cars and electric buses, the cumulative number of vehicle IGBT modules is ranked first in China. In addition, BYD IGBT modules are also widely used in industries including industrial electrical equipment, home appliances, rail transit, and solar inverters. Within the various types of power electronic equipment.
Driving and charge-discharge multiplexing and fusion technology to solve the large-scale application problems of pure electric buses
BYD realizes the multiplexing and fusion of driving and vehicle-mounted charge and discharge functions through a set of IGBTs, invents the drive and charge-discharge multiplexing fusion motor controller, and realizes a highly integrated design scheme for driving and charging and discharging. Drive and charge-discharge multiplexing and fusion technology innovation The existing external charging solutions for various types of charging equipment have broken the dependence of electric vehicles on charging equipment, effectively solved the problems of large space, high cost, and disadvantages of popularization brought by DC charging stations. In addition, driving and charging The on-board charging power of the discharge-reuse fusion motor controller reaches 40kW, which greatly reduces the construction cost of the charging pile.
BYD pure electric bus charging equipment
In practical use, this leading technology has greatly promoted the large-scale promotion and operation of BYD's pure electric buses in the global market, and has also promoted the acceleration of the development of national electric vehicle electrification. BYD's pure electric passenger car charging equipment covers a small area and has a parking lot. A charge pile can be built at the end of the bit, which requires low requirements for the site and power supply. In addition, this technology can help the vehicle achieve bi-directional inverter charging and discharging functions. In areas where earthquakes and other natural disasters occur frequently, BYD pure electric buses are equivalent to one. A mobile large-scale power supply can supply external loads (such as refrigerators, induction cookers, etc.) to solve emergency power problems.
The development of new energy vehicles and the realization of electrification of public transport have become China’s national strategy. Today, the number of new energy vehicles in China has reached 1.8 million, and it has been the world’s first in three consecutive years in production and sales. Among them, BYD’s sales of new energy passenger vehicles have been for three consecutive years. It ranks first in the world, and the sales of pure electric buses ranks first in the world for four consecutive years. In the process of China’s transition from a big automobile country to a powerful automobile country, the breakthrough in key technologies of electric vehicles is an indispensable factor, and it is also a core competitiveness. reflect.
As the initiator of the new energy overall solution, BYD upholds the concept of “Technology is the king for innovation”. In addition to the IGBT sector, BYD has leading technologies in the core areas of electric vehicle battery and management systems, and masters the development of components from the ground floor. The core technology of the entire industry chain integrated into the drive system is to truly promote the development of green transportation with technological innovation and satisfy people's longing for a better life.
