BYD: increased investment on research and development of new energy vehicles

BYD will intensify IGBT module of research and development, on the one hand, improve the electrical performance, meet the needs of new models, on the other hand extend IGBT module of the size of the market, to reach the foreign sales.

Experts say: in the future, BYD will increase the intensity of IGBT module of research and development, on the one hand, improve the electrical performance, meet the needs of new models, on the other hand, expand the IGBT module of the size of the market, to reach the foreign sales.

BYD Company Limited has great importance to the development of new products and new technologies and innovative work, the new product research and development as a Company to maintain the core competitiveness of the important guarantee.BYD has always attach great importance to the development of new products and new technology, with a strength outstanding research and development team, more research in the field of system is constructed and strong patent reserves, made in the company battery, motor and electric control, and other fields have the world's leading technical strength.Electric control system of daily work, is through the electronic signal would transmit the energy allocation to round, at the same time will be around the whole vehicle sensor, the information feedback in time, the exchange of each part.

In the related report, BYD electronic control was described in detail the latest technology:

Electric control design, BYD has provided the independent research and development of BYD BM3451/3452 series IC, both has the characteristics of high precision, high integration.By monitoring the battery voltage, charge and discharge current and temperature of the ring and other information to realize the battery charge and discharge protection, over current, temperature protection function, can adjust the overcharge by external capacitance, discharge, over current protection latency.In addition, BM3451/3452 series can use a variety of packaging forms, to provide customers with customized chip size.

BYD has the VCU/MCU core technology, the development of this technology is in the charge of internal BYD auto engineering research institute.Pure electric vehicle controller for VCU, hybrid quill for HCU, in these two aspects, BYD has mature technology, the technology through the sensor signal acquisition drivers, through CAN bus for motor and battery information, share and operations, through CAN bus after motor and battery management instruction is given, to realize the vehicle drive control, energy optimization control and feedback control.

Motor controller is mainly composed of control circuit, drive circuit, the structure of the shell and various sensors.One of the most important thing is to drive circuit of IGBT module, in the electric control system of cost accounted for about 40%.BYD is the vehicle manufacturing enterprises, production and form a complete set of electronic products, as a result of the new energy automotive IGBT chip application condition is more complex, high temperature and high humidity high vibration and assembly requirement is very strict, such as volume, cost, this gives BYD IGBT chip research and development and production, higher requirements are put forward.

Experts say: in the future, BYD will increase the intensity of IGBT module of research and development, on the one hand, improve the electrical performance, meet the needs of new models, on the other hand, expand the IGBT module of the size of the market, to reach the foreign sales.
