Yuasa Battery Sales (UK) has announced the availability of new battery modules for its LIM family of industrial Li-ion batteries. Designed for use in a wide range of applications including energy storage, traction motors and regenerative energy recycling, the new battery modules incorporate multiple LIM series battery cells along with a battery monitoring unit (ACS) and a temperature sensor. The ACS monitoring unit measures temperature and voltage of the cells and outputs a signal to an external device enabling users to monitor the condition of the battery accurately. The ACS also performs cell balancing and can detect abnormal operating conditions such as high or low voltage.
Yuasa LIM series Li-ion batteries offer a number of enhanced features compared with previous generation products. These include lithium transition metal oxide as the positive active material and carbon as the negative active material, increased energy density in comparison with lead-acid, nickel-cadmium and nickel-hydrogen batteries, completely sealed structure, outstanding cyclic characteristics significantly above lead-acid performance, high charging efficiency to save energy, no memory effect eliminating the need for complete discharge or for spare batteries and better rapid charge/discharge (high power) characteristics.
Yuasa LIM series industrial batteries are designed to work with a battery management system (LIBM) which features a LCD touch panel showing battery voltage, current, temperature and cell voltages, SOC (state-of-charge) and any abnormalities in real time. In the event of an abnormal condition occurring, the LIBM cuts off current automatically to protect the battery.
Typical applications for the Yuasa LIM series battery include railway transportation, gantry cranes, automated guided vehicles, electric vehicles, energy storage systems, broadcast power supply, photo voltaic (PV) systems and uninterruptible power supply (UPS) systems.
