The Chinese Remainder Theorem (CRT) is a mathematical theorem used in various fields, including computer science, cryptography, engineering, number theory, and physics. One of the real-world applications of CRT is optimizing electric vehicle (EV) charging infrastructure. Developing a robust and efficient charging network is essential to maximize the potential of EVs and reduce the reliance on fossil fuels. To achieve optimized EV charging, smart charging systems can be used to ensure EVs are charged at the most efficient times, and fast charging stations can be installed in key locations. It is also important to ensure that the energy used to power EVs comes from renewable sources. By optimizing EV charging, we can minimize the time it takes to charge an EV, reduce the overall cost of EV ownership, and make electric vehicles a more convenient and affordable option for drivers.
