Battery swapping is that curious legacy solution that just refuses to die. And now one of the leading players, Ample, has debuted a station promising “recharge” times of 5 minutes!
We previously spoke about the battery swapping phenomenon and arguably its most high-profile failure. Startup Better Place rai

Less than 30 years ago, not much thought was given to battery technology. Today the electrification of transportation market, as well as R&D investment in related technology, is fueling the need for batteries. Plus, the high use of uninterruptable power supplies in healthcare, process control, mission-critical IT

Figure 1. The battery fuel gauge can be implemented on the host side or in the battery pack
In this era of mobile devices, battery life is one of the primary factors that affects the user experience. While implementing power saving technology inside devices is important, it is only one part of the solution. Given the increasing capabilities—and greater power requirements—of mobile devices, original eq

Figure 1: A typical Battery Management System for lithium ion batteries
As the demand for increased energy storage capacity grows, engineers are frequently challenged to place multiple batteries in parallel. Using multiple batteries can offer extended runtime, enhanced reliability, and the ability to carry energy to different locations that may not have charging capabilities. With th

Figure 1: A battery pack assembly featuring Interplex Cell-PLX™ interconnect technology
The battery pack is the most vital element of any electric vehicle (EV). It is through this that the electricity needed by the drivetrain is supplied. The battery also represents the most expensive part of an EV - having a major influence on its overall bill-of-materials (BoM) costs. Ensuring that it delivers pr

Welcome to the July edition of Power Systems Design Europe. I’m not sure what the weather is like where you are, but as I write this, here in Scotland the sky is blue and the temperatures are in the mid 20s Celsius. When the weather is like this, there is no better place to be. July is the start of holiday se

We’ve now passed the official start of summer, and at the risk of sounding cliché, things are about to heat up with one of – if not the – hottest topics for our publication, batteries.
Batteries are uniquely critical in that they’re vital to myriad portable devices and the electric vehicles in operat
