BMS System Controlled Object Core Knowledge – Overcharge
Concept overcharging, or overcharging, is a type of lithium-ion battery abuse where the charging voltage of a lithium-ion battery is too high above its charging cut-off voltage. Lithium-ion battery charging usually set charging cut-off voltage, the process needs to use constant current and constant voltage charging method to avoid overcharging the battery. However, in special circumstances, such ...

Why does the lithium ion battery explode?
Lithium battery, I think we should be more rigorous. It should be called lithium-ion secondary battery. Li is the smallest diameter and most active metal on the element periodic table. If you are not sure, you can look at the periodic table “Lithium hydrogen helium beryllium boron, carbon nitrogen, oxygen, fluorine and neon…”. Because Li has these characteristics, it is widely ...

How the thermal runaway test chamber works?
As the valve-regulated battery uses a poor liquid design, the electrolyte poured into the battery is adsorbed on the fiberglass board. When the charging current increases, the gas needs to be released through the safety valve, which causes the battery to lose water and increase the internal resistance. The capacity decay and generate a lot of heat during charging and discharging. If the heat is ...

What Reduces Battery Life?
Batteries have become the lifeblood of today’s machines, devices, and equipment. Batteries enable us to use them without an electrical connection. But batteries, as we know, have limited capacity. Sooner we’ll have to plug our laptops, our phones, or replace our car batteries. Batteries have a predetermined lifespan as indicated by the manufacturers’ specifications. However, ...

A new life estimation method for lithium–ion batteries in plug–in hybrid electric vehicles applications
This paper presents a new approach to life estimation for lithium–ion batteries used in plug–in hybrid electric vehicles (PHEVs) applications. A new framework for battery life estimation is developed which investigates the effects of two primary factors of battery life reduction in PHEVs applications, namely, depth of discharge (DOD) and temperature (Tbatt), under typical driving conditions, ...

Heat Flux Sensing in Battery Monitoring
Batteries are critical devices for many people today: they power smartphones, laptops, and even cars! The wide adoption of batteries was possible because of the invention of the lithium-ion battery (whose inventors won the Nobel Prize this year). If we look at its results, the Li-Ion battery was surely one of the most important engineering achievements of the last 50 years. Given its importance, ...

Solar Streetlights in Extreme Weather
Nature is brimming with its different forces. They are all meant for good but can have a damaging effect on other items that it comes into contact with. Take for example anything that is outside but is not natural. It can easily get damaged by water and get rusty. Even natural things can be blown away or struck down by the very same beautiful nature. It is very easy to assume that streetlights ...

Ambri Is Still Alive and Chasing Its Liquid Metal Battery Dreams
Among the ranks of lithium-ion alternatives these days, simply staying alive counts as above average. Ambri, the liquid metal battery startup spun out of MIT materials research, has achieved that distinction with flying colors. After halting commercialization to address a technical problem with the seals on its high-temperature battery cells, the company started afresh with a new, lower-cost ...

A Heated Discussion on Lead-Acid Batteries
Having just endured one of the hottest Julys on record, many people have been subjected to extremely hot environments lately. And, in some cases, where their bodies have produced or absorbed more heat than they could dissipate, people have been experiencing an abnormally high body temperature due to the failure of their body to thermoregulate. This is called hyperthermia. In fact, as I wrote ...

How a Solar Light Works
A solar light is a light that has the ability to convert sunlight from the afternoon hours into electrical energy that eventually powers the light whenever it is required. It looks no different from a regular light but there are very many subtle differences in the background. A solar panel collects the sun’s radiation and then transforms it into electrical energy. The converted electrical ...

Fiber Optic Testing Helps Ensure EV Battery Health and Safety
EVs face unique design challenges in order to be competitive with gasoline-powered vehicles. The root of many of these challenges is in the EV battery pack. Drivers want similar vehicle range per charge when compared to a tank of gas, as well as the convenience they are used to with refilling a tank in just a few minutes. This means battery packs need to be able to store enough energy to go ...

Monitoring Off-Gasses to Guard Against Thermal Runaway Risk with Li-Ion Batteries
Lithium-Ion Batteries Rechargeable lithium-ion (“li-ion”) batteries (comprised of cells in which lithium ions move from a negative electrode through an electrolyte to a positive electrode during discharge—and the other way around when charging) were first described conceptually in the 1970s. Following initial prototype development in the 1980s, li-ion batteries became ...
