Before you even charge your EV for the first time, the battery undergoes controlled charging cycles in the factory itself. These initial charging cycles are slow and time-consuming as they occur at low currents. A Toyota-funded study discovered that high currents during initial charging phases improve performance and lifespan. The electric vehicle movement isn’t linear. … Continue reading “To Boost EV Battery Health, This Unexpected Step May Be Groundbreaking”

Kia EV9 high-voltage battery pack teardown by Munro & Associates reveals engineers likely thought about repairability when designing it. There are two access plates underneath for serviceable items. If a battery module needs to be replaced, the whole pack is very easy to take out of the vehicle and disassemble. The 99.8-kilowatt-hour high-voltage battery pack … Continue reading “Kia EV9 Battery Pack Teardown: ’A Wonderful Design’”

Lithium iron phosphate (LFP) batteries are cheaper to produce and more stable than traditional nickel-based chemistries. A new study from a Tesla-funded lab found that LFP batteries degrade faster when fully charged. Repeated charging at a higher state of charge increases negative reactions within a pack. Electric vehicles powered by lithium iron phosphate (LFP) batteries … Continue reading “LFP Battery Health Degrades At Full Charge, Study Finds”

Maintaining precise control of humidity is essential for manufacturing lithium-ion batteries, and the most efficient way to do that is with desiccant dehumidification. While dehumidifiers may look similar on the outside, it’s what’s inside that counts. In fact, not all components and construction methods are alike, and those differences can have a significant operations impact … Continue reading “Download the battery dry room dehumidifier design and construction guide”

The average price of a lithium-ion battery pack for a light-duty EV has decreased 90% over the past 15 years, the U.S. Department of Energy (DOE) estimates. In 2023, the DOE estimates pack prices averaged $139/kwh on a usable-energy basis for production at scale, meaning at least 100,000 units per year. That’s still not quite … Continue reading “EV battery costs dropped 90% in last 15 years”
