The past and present of battery management technology

Living in a technologically perfect day, it is easy to forget the “primitive” state of life we ​​had a few years ago. At that time, we also used products such as phonebooks, paper tickets, and DVD players. If the emergence of electronic products changes our way of life, then the development of battery technology has changed the electronic products we love.

The past and present of battery management technology

The evolution of battery technology is closely related to the use of battery-powered devices and systems. As people have become accustomed to the convenience of mobile computing and communication devices, the industry has also placed higher demands on portable power supplies. However, advances in battery technology have in turn led to a variety of new mobile applications, some of which are beyond our imagination.

Although battery technology has developed relatively fast in the past few years, its basic concepts have not changed much. In 1936, archaeologists discovered a handicraft more than 2,000 years ago that looked like a battery. So is this device really a battery? Most of today's experts question this view, but some people agree. If we look back at history, we will find that the development of battery technology has been rapidly improved in the 17th and 18th centuries, and eventually became the power source for emerging electronic devices such as electric lights and radios in the 19th and 20th centuries. About 100 years ago, "dry batteries" began to be used gradually, and the batteries are very similar to the ordinary disposable batteries we use today.

Over time, lithium-ion batteries were commercialized in the early 1990s, and people began to pursue more sophisticated electronic monitoring circuits. Because the new lithium-ion battery has many advantages in terms of energy and overall performance, system designers are willing to invest a lot of time, effort and money to develop specialized battery management circuits to optimize the life cycle of these batteries.

On the other hand, as people become more dependent on batteries, battery technology and related technologies are also evolving. Batteries were one of the most troublesome components of early mobile devices because end users couldn't accurately predict when the system was running out. At that time, almost all of the electronics' batteries could be easily removed or replaced. Today, thanks to continuous advances in technology, batteries can be seamlessly embedded into portable devices. At the same time, thanks to the accurate and reliable built-in battery monitoring technology, users can now accurately understand the status of the battery at any time. In addition, users can easily and quickly charge the battery, and with wireless power technology, users can charge without even needing any physical connection.

Imagine, after a few years, when we can travel by plane with a smart watch, will you miss these good times now?
