Adaptive control of V2Gs incorporating EV owner expectations
Australian researchers have developed a novel adaptive decentralized control strategy for electric vehicle (EV) integration, incorporating both microgrid and EV-side conditions into the primary frequency control. They have proposed new indices to evaluate the charge and discharge capabilities of EV batteries, as well as the satisfaction levels of EV owners.
Role of hydrogen, batteries in UK’s decarbonization efforts
Hydrogen and battery technologies are expected to play an increasingly vital role in the UK’s transition to net zero by 2050, but the varying time scales of their rollouts are driving uncertainty in predicted market share profiles over time, according to a new report.
CATL launches 500 Wh/kg condensed matter battery
Chinese battery industry heavyweight CATL has unveiled a novel condensed matter battery technology with an energy density of up to 500 Wh/kg. The company said it can achieve mass production within this year.
PV-powered robotic lawn mower from New Zealand
Researchers from Massey University in New Zealand have developed a robotic lawn mower with three 50 W solar panels and a 20 Ah lithium-iron-phosphate (LiFePO4) battery. Two of the PV panels can be retracted and stacked inside the robot. They slide out when it needs to recharge its batteries.
Tesla Master Plan projects 3 TW of solar and 6.5 TWh of storage in US
Tesla releases its third Master Plan, with a broad focus on clean electricity generation and storage, as well as related manufacturing costs.
Viessmann adds Wallbox to PV-battery-heat pump package
