Thorsten David, General Manager, Product Development, Global Transmission Fluids & Advanced Electrification Fluids, Castrol

Thorsten David, General Manager of Global Transmission Fluids & Advanced Electrification Fluids R&D at Castrol, shared a keynote speech on ‘Next Generation of High Performance, Low Viscosity EV Transmission Fluid Technology’, stating that the biggest obstacle to the electrification transition is still the challenges of range, charging, and pricing, and that innovation and development of EV transmission fluid technology will play an important role in this! The presentation introduces Castrol's innovative development and in-depth research work on low-viscosity EV transmission fluid technology.

Low-viscosity EV transmission fluid technology has great potential to improve the transmission efficiency of electric drive transmissions and motor cooling efficiency. However, a drop in viscosity will bring about the negative effects of thinning of the oil film and increased friction and wear, so reducing the viscosity alone will meet the bottleneck of efficiency improvement, and the drop in viscosity poses a greater challenge to the performance of the gearshafts and other hardware protection, Castrol can provide the best solution for different electric drive transmissions, based on a full range of local and global technological resources. Based on comprehensive local and global technical resources, Castrol can uniquely design low-viscosity fluid formulations to meet the characteristics and needs of different electric drive transmission hardware designs, fully exploiting their maximum potential for efficiency improvement while providing balanced and outstanding hardware protection performance to help electric vehicles run efficiently and smoothly.

Chen Wei, Vice President of Huawei Digital Energy Intelligent Electric Product Line, brought the topic of ‘Broad View, Thick and Thin - Powertrain Technology Trend Sharing’, in which he said that extreme efficiency, extreme integration, and driving control and safety will become the key direction of future powertrain development and innovation. After the development in the past few years, the efficiency of SiC assembly and IGBT assembly has been increased to 92% and 90% respectively. With the maturity of SiC, superconducting copper wire, mirror grinding gear shaft and other technologies, the efficiency of the assembly will be further improved, with the popularity of super charging and 4C battery to completely solve the range anxiety.

At the same time, X-in-one technology has been widely recognised by the industry, and in the future, it will move from the simple integration of discrete components to the in-depth integration of the four dimensions of domain control, chip, power, and function, and with the platform software development platform, enhance the product power of the whole vehicle.

Finally, in the dimension of driving control and safety, the traditional torque control system can not match the electric drive output of large dynamics, the occurrence of unintended torque output, torque control will move towards a short link high real-time solutions to enhance the driving experience, to ensure driving control and safety.

The conference will last for 2 days, and 5 parallel forums will be held during the same period, with full coverage of electrified power system: electric drive system, hybrid power system, drive motor, power semiconductor, and commercial vehicle power system forums, welcome to stay tuned.
