German engineers have developed new sensor technologies that can reduce the weight and cost of electric vehicles and other types of lithium-ion batteries.
Philip Dost is a member of the Ruhr University Power System Technology and Electrical Mechatronics Research Team. The team developed a new concept for monitoring battery currents and voltages, reducing the technical burden on the battery and adding New features.
Typically, an electric car battery consists of a single battery that can contain up to 12 batteries, each monitored by its own voltage sensor. Sensors are important for monitoring lithium batteries in batteries. If they are overheated or overworked, they may burn.
In a typical electric car battery, there is a current sensor and multiple voltage sensors to do the job. The sensor is a considerable weight and cost driver.
To reduce weight, Dorst and his colleagues proposed a way to reduce the number of sensors that need to monitor current and voltage in an electric car battery to one, regardless of the number of cells in the battery.
Researchers said that the sensor system it developed could be extended to batteries with different monomer counts. It can also be applied to other battery types, such as tablet or laptop computers, wireless power tools, uninterrupted power systems, and solar energy storage systems, to reduce its weight and cost, and to increase battery life.
Next, Ruhr University engineers will continue to work hard to improve the technology, more closely assess their prototypes and replace individual components to meet the requirements of the automotive industry.
