Abstract
Description
[0001] A SYSTEM GENERATING ELECTRICITY BY DAMPING EXPANSION IN A BATTERY
[0002] Technical Field
[0003] The present invention relates to a system which stores the mechanical energy resulting from the expansion and contraction generated during the use of the battery cells of a foam made of magnetostrictive material included in a lithium- based battery pack on the battery by converting it into electrical energy.
[0004] Background of the Invention
[0005] Lithium-based batteries are used to enable electrically powered vehicles and portable devices to operate and / or the energy from energy storage systems to be stored since they have high energy density and fast charging / discharging features. Expansion and contraction formation are observed on the cells of lithium-based batteries during their use. The expansion and contraction occurring on the battery causes the internal pressure to increase by disrupting the structure of the cells. The increase in pressure in the battery cells results in the cells exploding and the electrolyte liquid inside the cell leaking out, and causes poor performance in the battery and / or the battery to become unusable. In today's applications, there are applications that enable the electrical energy generated in a plate formed by using magnetostrictive material positioned inside the battery to be stored. However, the said applications do not absorb the expansion of the battery cells and do not enable the electrical energy to be generated by using the internal pressure change due to cell expansion. For this reason, in the state of art, there is a need for a system which dampens the expansion of the cells during their use and converts the force generated on the foam during the dampening of the expansion of the cell into electrical energy, and enables it to be stored in order to enable the safe, efficient and environmentally friendly operation of the cells of the battery.
[0006] The Chinese patent document no. CN110112956, an application included in the state of the art, discloses a magnetostrictive instantaneous impact energy collection and warning system. The invention subject to the said Chinese patent document belongs to the field of vibration collection and utilization, and relates to a giant magnetostrictive instantaneous impact energy collection and warning system by taking giant magnetostrictive sheet materials as core elements and generating electric energy by absorbing vibration. One end of the crank of the system is installed on the platform, the other end of the crank is connected with a sliding block arranged on the platform through a connection rod, an L-shaped plate is connected with the platform, a giant magnetostrictive material sheet is fixed on the L-shaped plate, a pickup coil winds the giant magnetostrictive material sheet, the wire end of the pickup coil is connected with the input end of a rectifying filter circuit board, the output end of the rectifying filter circuit board is connected with the input end of a lithium battery, and the output end of the lithium battery is connected with a warning lamp. The pickup coil is configured to pick up the electric energy generated in the power generation process to achieve the energy collection and utilization process of converting vibration energy generated in the instantaneous impact process into energy output.
[0007] Summary of the Invention
[0008] An object of the present invention is to realize a system which stores the mechanical energy resulting from the expansion and contraction generated during the use of the battery cells of a foam made of magnetostrictive material included in a lithium-based battery pack on the battery by converting it into electrical energy.
