The 'T' power of high 'values' has brought top quality Chinese industrial design to the world stage. Of course, sales of nearly 100,000 units at home and abroad have confirmed that 'T' power has more reliable performance. Behind this, CRRC Electric R&D personnel have struggled for many years and struggled with the sweat of the Miracle Flower.
Targeting New Energy Passenger Cars
The electric drive system has been hailed as the 'heart' of new energy vehicles. In the area of new energy commercial vehicles several years ago, this 'heart' (including electrical control, transmission control, energy storage control, etc.) was also dispersed in various vehicles. The location, the layout of the circuit is very complex, the production efficiency is not high.
Only one company can only innovate and find the right footing to have a foothold. In 2014, at CRRC Electric, a bold idea was put on the agenda.
'Why can't we make electric drive system integrated control?' The idea that came up with this proposal was Liu Ling, general manager of CRRC Electric. Recalling the decision made at the time, he lamented: 'We must integrate so many components and functions into one. On the product, there is no experience to learn from abroad. There is no similar product in China. We can only touch the stones and cross the river.
In the absence of any experience to follow, the research and development of the electric drive system ushered in a breakthrough. In 2016, CRRC Electric's fourth generation 'T' power was the first electric drive system integrated product available. As it is large and heavy, including Company leaders including Liu Ling believe that this product can do better.
According to Liu Ling, in the era of increasingly fierce competition in the new energy commercial vehicle market, the problem of electric drive systems cannot be solved. Enterprises cannot have independent core and key technologies, and it is difficult to achieve sustainable development. A year later, Liu Ling decided to restart the project. Organize scientific research and development to develop the fifth-generation 'T' power.
R & D personnel 'down time difference' to overcome technical difficulties
In order to unveil the 'box' of 'T' power, project manager Yang Hongbo and his team made a lot of innovations and changes on the basis of the fourth-generation products, and made products in depth in mechanical structures, high-voltage circuits, and control circuits. Integrity, which is equivalent to holding five fingers into one fist, forming a resultant force.
The R&D process was not easy. The biggest difficulty came up: The burning of the vehicle control chip caused a shutdown. Even if a new chip was replaced, it would be burned again.
Yang Hongbo and the R&D staff were very worried about the problem. In order to detect the problem as soon as possible, they carried out countless investigations and verifications. Numerous modifications were made while debugging. This process was extremely annoying. Soon after, the laboratory passed the final analysis results: The abnormality occurred at the station due to the fact that the two wires of different voltages collided. The 'box' was finally opened and the experiment continued.
After the first batch of prototypes came out, R&D personnel entered an intense test phase. In the middle of the night of silence, R&D personnel were most reluctant to hear the sound of large trucks leaping out of the window because it was likely to cause magnetic fields around the laboratory. Fluctuates, eventually leading to invalid test results.
The subsequent shockproof test lasted for 3 days and 3 nights, and the R&D personnel took turns in the laboratory. After the test was successful, everyone said jokingly to each other that this was the first test project that had to participate in the 'down time difference'.
'High face value' 'T' power to the world stage
The struggle for life is itself a kind of happiness. After the unremitting efforts of CRRC electric researchers, the fifth-generation pure electric drive system platform 'T' power was drawn from the initial vision into drawings, then from drawings into physical objects, and eventually mass produced. , Those hardships, the hardships finally get a happy smile.
Compared with the previous generation, the fifth-generation 'T' power volume is reduced by 62%, the weight is reduced by 33%, the production efficiency is improved by 10%, and the total assembly efficiency is increased by 60%, the quality reliability is 99.5%, and the electromagnetic compatibility at home and abroad is fully complied with. Design and regulations.
The pursuit of intrinsicness and trend, CRRC has always been fearless. Products have 'value' but also have 'value'. Newly designed 'T' power products, from the inside out, show CRRC electric 'technology The beauty of the 'understanding' and exploration, thus seizing the 'IF' design award known as 'Industrial Design Oscar'.
Today, the fifth-generation 'T' power of CRRC Electric has been sold throughout the country and entered the international market. CRRC Electric has become the industry leader and has made 'Zhuzhou Zhizhi' shine on the world stage.
