Ev Battery

9 GoKawiil briefs on this topic

EV-to-home power requires bidirectional hardware most cars and chargers lack

Many EVs carry enough battery capacity to power a house, but doing so requires vehicle-to-home (V2H) compatibility, a bidirectional charger with a DC-to-AC inverter, and an islanding or transfer switch. Without that specific hardware, energy cannot flow backward from the car into the home, regardless of battery size. The report also distinguishes V2H from vehicle-to-load (V2L), which only powers individual devices rather than an entire household.

GM Product Chief Anderson: Humanoid Robots Not Suited for Car Manufacturing

Speaking after GM's New York event unveiling its AI-driven 'intelligence-defined vehicle' strategy, chief product officer Sterling Anderson said he does not believe humanoid robots are the right tool for building cars. The broader roadmap centers on centralized computing, new battery chemistries, and virtualized engineering aimed at cutting vehicle development time roughly in half.

Geotab study links frequent DC fast charging and heat to faster EV battery wear

Fleet-data firm Geotab analyzed EV charging patterns and found that vehicles using DC fast charging for 12 percent or more of sessions degraded at 2.5% annually versus 1.5% for infrequent fast-chargers. Combining frequent fast charging with high power (over 100 kW) pushed degradation to about 3%, and cars in hotter climates degraded roughly 0.4% faster than those in milder regions.

EVs drain battery while parked due to background systems, automakers confirm

Tesla and Rivian confirm that even when locked, their EVs run periodic battery management checks and use the high-voltage battery to recharge smaller 12V systems that power locks and computers. Tesla says app requests, climate preconditioning and infotainment also draw power while parked, and cold weather can skew range estimates independent of actual energy use.

GM Uses AI Simulation to Compress Battery Testing Timeline

General Motors says it used simulation technology to virtually test hundreds of thousands of battery configurations, completing the equivalent of 34,000 years of testing in under a month. The company now plans to apply the same simulation approach across other stages of vehicle development, having already spent roughly a decade researching lithium manganese-rich batteries that have yet to reach production vehicles.

Report outlines EV charging habits that speed up battery degradation

A new report details common EV charging behaviors that can accelerate battery wear, including habits like routinely charging to 100 percent, charging in extreme heat, and frequent use of DC fast chargers. Instead, the report recommends keeping charge levels between 20 and 80 percent for most driving, varying ideal caps by battery chemistry (LFP vs NMC), and favoring Level 2 charging over Level 3 when possible.

Report details which driving habits drain EV batteries fastest

A roundup of findings explains that highway driving, high speeds and hard acceleration drain EV batteries faster than stop-and-go city driving, partly because highway trips offer less opportunity for regenerative braking. Climate control systems, especially heaters, also reduce range noticeably, while infotainment and navigation systems have minimal impact. A 2025 Recurrent study found EV range can drop nearly a third below freezing and about 18% at 100 degrees, with cargo and passenger weight further cutting range.

How to decide if your EV needs a Level 2 home charger

Electric vehicle owners can charge at home either through a standard household outlet or by installing a faster Level 2 charger. The choice depends on factors like battery size, the car's maximum AC charging speed, and daily driving distance, rather than a need to always charge to full like a phone. Home charging remains far cheaper than gasoline, roughly a third of the cost, even before factoring in a Level 2 upgrade.

How EV owners can tell when battery degradation, not weather, is cutting range

EV batteries naturally lose some usable capacity over time, with the Department of Energy estimating a 12-to-15-year lifespan in moderate climates and 8-to-12 years in harsher ones. A 2026 Geotab study of more than 22,700 vehicles across 21 models found average yearly degradation of about 2.3 percent, though results vary widely by car and driving conditions.
