According to foreign media reports, Ken Pence, a professor of engineering practice management at Vanderbilt University, and Tim Potteiger, a doctoral student in the School of Electrical Engineering, jointly developed a battery management device that reconfigured battery modules for electric vehicles, Sira's high-energy-density lithium-ion battery model was set up to improve the durability of the battery and improve the life cycle of the electric car, which can increase the mileage of the electric car by 50%. In addition, they also provide batteries for each cell Added controller.
Tim Potteiger said: 'We realized that some cells consume more electrolyte than other cells and when they are depleted, the efficiency of the other cells is reduced, but we have found a way to get all the cells The energy is consumed simultaneously, without differences in energy consumption.
Potteiger said the electric car's battery gauge reserves the lowest battery charge to keep the passengers from getting trapped. When the battery charge is 10%, the battery gauge will show "no battery" status. Connect the electric car vehicle software, so the driver can accurately read the power information, maximize the use of battery power to maximize the electric car mileage. Pence said the older the battery, the more likely problems, the lower the efficiency, then the battery The more useful the device is to manage it.
"With this device, the useful life of the battery will be longer," said Pence. "Drivers will not immediately feel 50% more mileage, but they will find battery life extended later."
In addition, the two are working with Vandenberg University's Technology Transfer and Commercialization unit to bring the device to market.
