The key of the battery life puzzle: lithium batteries and ultra-capacitors

Today, traditional automobile electronics have already accounted for 40% of the cost. The proportion in electric cars will be bigger, only some batteries have accounted for about 40% of the total cost. In the electric car market, Tesla is a flag.

Just finish the first delivery of the tesla Model3, let consumers "range anxiety" greatly alleviated. Relative to the $69500 tesla's 259 - mile range, up $35000 Model3 has a 220 mile range.

Pure electric vehicles, however, there is another serious problem - the battery life. Although the lithium battery in ordinary electronic products on the average service life can be up to eight years, but good performance on the electric car battery charging and discharging number only about 700-900, equivalent to life for 3 to 5 years. However, in battery costs are too high, equivalent to bought a new car.

In the face of lithium battery of charging problem such as slow, short range, short service life, the United States, Russia, Switzerland, Japan and other countries are stepping up the development of super capacitor, and super capacitor in electric vehicle drive and the study of the application of the brake system, the industry there are super capacitors instead of electric motor vehicle battery's point of view.

Taken together, that have existed in the field of electric vehicles lithium battery and super capacitor two forces, both have stepped up their own research and development.

"Nowadays, lithium battery and super capacitor researchers are committed to enhance both its service life, but from the chemical point of view, according to the forecast it takes 5 ~ 10 years there will be a remarkable achievement. Confucianism cuori (Rutronik) as a leading global electronic distributors, not only have the lithium battery and super capacitor factory resources, and its own engineers, industry experts. Two years ago, Confucianism cuori zwickau with Germany at the university of applied sciences (WHZ) from the lithium battery and super capacitor advantages together ideas, research and backwardness of the current industry and related proposals, thus promoting the study. Today, based on the idea of hybrid energy storage system (HESS) in the power management was born, this is the first combination of battery and super capacitor, and has been popularized in Germany, we hope to have more Chinese clients can also use this product and benefit from it." Confucianism cuori AndreasMangler strategic marketing and communications director, said.

Zwickau, says Dr LutzZacharias, a professor at the university of applied science with Confucianism cuori cooperative research and development of the hybrid energy storage system power management, the main feature is the combination of antihypertensive or booster (MOS) topology, digital control power supply circuit, flexible configuration, control parameters, low impedance characteristics for high impedance battery system, so you can through digital control can greatly improve the peak current of energy storage system performance, try to minimize the battery degradation, but also can ensure more flexibility on the performance. This new type of hybrid energy storage solution could be applied to many fields such as communication, automation, etc, the key application will be electric cars, electric cars, which can realize high reliability, but also the potential of further development.

In order to more clearly on the hybrid energy storage system power management to display, Confucianism cuori engineer in electric tool to tighten the screw process, for example, highlight the characteristics.

Since this technology can realize the service life of the energy storage system, so what age is the most reasonable? Mr Andreas Mangler said, our goal is to realize the lithium battery life with product life close, best match, the life is according to the requirements in terms of electric control part of the debugging, and now can achieve this goal.

At present, the Confucianism cuori 60% of the revenue from the auto market in the Chinese market, and the new energy vehicles is power is the focus of the hybrid energy storage solution domain. Confucianism cuori Asia marketing director Huang Zhijing said, China is now vigorously promote new energy vehicles, the HESS scheme will be right power battery provide enhanced reliability and recycled, making electric cars performance by leaps and bounds, will be great help for innovation in China.
