To Be Used for Electric Vehicle Charging
LS Cable & System announced on Nov. 9 that it will participate, along with its subsidiary LS Materials, in a government-promoted national project for the development of a hybrid energy storage system (H-ESS) for charging electric vehicles.
The project will focus on the development of an H-ESS, a product that boosts the stability of power supply and lowers risks by combining lithium-ion capacitors with lithium-ion batteries in an ESS. Capacitors are special industrial batteries with advantages of high-speed charging and discharging and long lifespan. Their applications are expanding to the renewable energy, electric vehicle and factory automation sectors.
“An H-ESS enables a stable supply of electric power even during peak times when several electric vehicles are simultaneously charged at a charging station by making good use of lithium-ion capacitors’ high output,” a company official said. “Its stable operation of capacitors through a control system lowers the possibility of fire due to a thermal runaway. Its lifespan is 5 to 10 times longer than that of general energy storage devices. It has high energy efficiency as well.”
LS Materials will oversee the entire project based on large capacitor technology. LS Cable and System will develop temperature monitoring and charge/discharge control systems. It plans to produce an H-ESS prototype by 2023 and complete its demonstration test by 2025 at a charging station of E1.
