NGK develops new evaluation system
Summary
NGK INSULATORS (NGK) has developed an evaluation system that visualises the conditions of Li-ion rechargeable EnerCera batteries, including remaining battery capacity, together with ON Semiconductor Corporation (onsemi). The evaluation system is equipped with a battery sensing integrated circuit (IC) for monitoring the remaining battery capacity with high accuracy that onsemi has optimised specifically for EnerCera and ultra-low power consumption. In addition to remaining battery capacity, it enables the visualisation of conditions such as voltage and temperature, which helps save power and extend the lifespan of devices and systems. The evaluation system also eliminates the need for verification of individual data of battery, which had previously been required to measure remaining battery capacity, and can verify items such as the load and stability of EnerCera while the device is operating, making it possible to reduce the duration of development of devices, etc. Through a semi-solid battery that uses NGK’s original Crystal Oriented Ceramic Plate as electrodes, NGK realises characteristics sought in power sources for IoT devices such as high capacity, high output, high heat resistance, and a long lifespan, which were difficult to combine in conventional Li-ion rechargeable batteries.
