Smart Chip says that the health of your battery – Hardware.Info

Scientists at the Nanyang Technological University (NTU Singapore) have developed a smart chip that can tell you how healthy your battery is and whether it is safe to use.

 

If the battery in the smart phone or electric vehicle is defective and there is a risk of a fire, the smart chip will give a warning. Current warning systems work only when the battery is already overheated, making it too late to take action.

 

The smart chip was developed by professor Rachid Yazami of the Energy Research Institute @ NTU.De chip is small enough to be built into almost all batteries, the small batteries in mobile devices to the huge power packs found in electric vehicles and advanced aircraft.

 

Professor Rachid Yazami said inter alia that the risk of a fire flying and failing battery is very low. Of the billions of lithium-ion batteries that may be produced each year there is a chance of one in a million, which translates to about a thousand failed batteries per year.

 

 

“This represents a serious risk for electric vehicles, and even in advanced aircraft, where usually large batteries with hundreds of cells or more are combined to drive the vehicle or plane. In a chemical fire caused by a single failing cell, there exists One risk that the fire from spreading to other cells and batteries which can have an explosion. “

 

 

Patented technology

 

Embedded in the smart chip is a proprietary algorithm developed by Professor Yazami which is based on the thermodynamics of electrochemical measurements (ETM-technology). Current lithium-ion batteries have built a chip that can only display voltages and temperatures. The batteries of today contain chips that are not in a position to detect the symptoms of a malfunction and may also show only the approximate amount of charge of the battery.

 

The algorithm patented by Professor Yazami is able to analyze both the state of health and the state of the load by means of a three-dimensional graph. On a screen this looks like a ski trail on a mountain.

 

Professor Yazami’s vision is that each battery will be provided together with its chip, which will ultimately reduce the chance of burning batteries and can simultaneously charge faster. The smart chip Yazami professor took over five years to develop and is now marketed through its start-up, KVI Pte Ltd.
