New Linear Technology power manager and charger works with several battery chemistries
Linear Technology has introduced a versatile power manager and multi-chemistry battery charger. The LTC4020 features ±0.5% charge voltage regulation and operates across a 4.5 to 55 V input voltage range, with output voltage up to 55 V. Coupled with three selectable termination algorithms, the controller can handle a variety of battery-stack voltages and chemistries. A… Read more »
New paper: Planning public charging networks is NP-hard
A group of researchers from Hong Kong Baptist University have released a paper that addresses the problems of planning the locations of public charging stations. In Electric Vehicle Charging Station Placement: Formulation, Complexity, and Solutions, Albert Lam et al look at the issue from the standpoint of Hong Kong, which has ambitious plans to encourage… Read more »
EVSE: the low-hanging fruit of smart city buildout
How installing a few charging stations is more of a long-term solution than meets the eye. We often hear about the need for smart cities, smart grids, and sustainability in general, but what does it really mean? How can we ever hope to build a smart and sustainable global ecosystem, considering the energy-consuming path that… Read more »
