China EV (Electric Vehicle) Motor Controller Industry Report, 2016-2020
Battery, motor and ECU are the three core components of new energy vehicle. EV drive control is one of core technologies for EV. Design of motor controller and development of control algorithm are critical factors determining performance of the whole drive system.
Motor controller prices vary greatly depending on specification and performance, generally RMB30,000-50,000 for large bus and RMB5,000-15,000 for passenger vehicle. PHEV and HEV usually adopt multi-motor architecture, including TM motor and ISG motor, thus resulting in higher costs of motor controller.
Furthermore, the evolution of EV e-drive system to wheel-side motor or wheel hub motor will also increase the cost of motor controller and complicate control strategy.
In such case, China’s demand for EV motor controller was 380,000 sets, generating a market size of around RMB6.3 billion (currently concentrated in commercial vehicle field) and, driven by new energy vehicle and conventional hybrid vehicle, estimated to swell to RMB29 billion in 2020 when passenger vehicle will prevail.
In particular, as hybrid vehicles are expected to be mass-produced on a large scale, either Corun Hybrid System Technology (CHS) co-funded by Geely and Hunan Corun New Energy or localization of Toyota THS will expand the market of homegrown motor controller in China.
Currently, the Chinese EV motor controller market is dominated by domestic brands, compared to fractional share of foreign products at the stage of market fostering and early development due to higher prices and other reasons.
BYD became the largest vendor in the Chinese electric passenger vehicle motor controller market with a share of 28.6% by shipment in 2015. The company purchases IGBT modules to assemble motor controllers which are supplied to its own passenger vehicle production bases. Other players with higher market share are Zhongshan Broad Ocean Motor (including Shanghai E-drive), Zhuhai Enpower Electric, Shenzhen Inovance Technology, and UAES.
From the perspective of industrial chain, IGBT module is the most core upstream component of motor controller. Global market size of EV IGBT module was about USD1 billion in 2015. Fairchild, Infineon, and ST have an upper hand in automotive IGBT market. However, Chinese BYD now is also engaged in IGBT. China accounts for about 1/3 of global IGBT demand but imports over 90% of its own demand. The IGBT modules produced by local companies are primarily used in low-power fields, such as air conditioner, induction heating, etc.
EV motor controller now employs mainly silicon-based IGBT module. However, SiC-dominated wide bandgap semiconductor devices have overcome the limitations of silicon-based semiconductor devices in terms of withstand voltage level, operating temperature, switching loss, and switching speed. For example, Nissan’s Leaf has integrated motor, speed reducer, and controller. This represents a trend in which the product can be more compact and standardized.
Another aspect of system integration is functional integration. EV may serve as an energy storage element of new energy grid in future, requiring bidirectional correlation of vehicle and grid (V2G). Vehicle-mounted motor control inverter can also be used as the inverter between battery and grid for charging and grid feedback, thus realizing integration of motor drive and bidirectional charger.
