KiloVault unveils new 1200 watt-hour deep-cycle batteries

KiloVault, a provider of innovative and affordable residential and commercial renewable energy solutions, this week unveiled the new 1200 HLX and 1200 CHLX heavy-duty deep-cycle lithium batteries. These 1,200 Watt-hour-capacity batteries complement KiloVault’s existing 1,800 Wh and 3,600 Wh models, and handle 80A of continuous charging current and 100A of continuous discharging current.

The smaller capacity and reduced weight of the 1200 HLX and 1200 CHLX make them ideally suited for applications such as marine and RV/camper use, golf carts, medical devices, and off-grid solar energy storage.

Like all HLX/CHLX batteries, the new 1,200 Watt-hour models can be used in 12V, 24V, or 48V configurations and feature Bluetooth communication for easy health and performance monitoring. This flexibility – combined with a 5,000-cycle lifespan (at 80% depth of discharge) and low cost/kWh cycle – offers customers exceptional value for their energy storage needs. Even after 2,000 cycles at 100% depth of discharge, a 1200 HLX or 1200 CHLX battery will retain 80% or more of its original 1,200 Watt-hour storage capacity.

KiloVault’s HLX and CHLX series batteries do not require active cooling, as the the lithium iron phosphate (LFP) chemistry used in their cells isn’t subject to the thermal runaway issues that other lithium technologies may experience.

These batteries do not require regular watering, desulphating, or equalizing and do not produce dangerous off-gassing like lead-acid batteries do – making them safe for use in your garage or even inside your home.

HLXs and CHLXs are incredibly safe and low-maintenance batteries, and outperform comparable lead-acid batteries by storing and discharging energy more efficiently to yield 12% more usable stored energy.

The 1200 CHLX features the same internal heating technology as KiloVault’s other CHLX batteries, which allows it to continue charging at subzero temperatures. As the ambient temperature dips below freezing (32F/0C), the charging current is rerouted through a heating film in the battery, allowing it to maintain an internal temperature above freezing. Once this is accomplished, the battery can resume normal charging.

DGIST enhances quantum dot solar cell performance


DGIST enhances quantum dot solar cell performance

by Riko Seibo

Tokyo, Japan (SPX) Oct 04, 2024







A research team led by Professor Jongmin Choi from the Department of Energy Science and Engineering at DGIST, in collaboration with Gyeongsang National University’s Professor Tae Kyung Lee and Kookmin University’s Professor Younghoon Kim, has developed a new method that significantly boosts the performance and longevity of perovskite quantum dot solar cells. Their innovative approach addresses a key issue: surface distortions on quantum dots that hinder solar cell efficiency.

Perovskite quantum dots are widely regarded as essential for next-generation solar cells due to their high light-to-electricity conversion efficiency and scalability. However, the process of replacing the “ligands” on their surface often causes distortions, akin to crumpled paper, that degrade solar cell performance.



The research team tackled this problem by introducing short ligands that firmly grip both sides of the quantum dots. This method effectively restores the quantum dot’s distorted surface, resembling the process of flattening crumpled paper. By smoothing the surface, they significantly reduced defects and improved both the performance and the stability of the solar cells. The power conversion efficiency rose from 13.6% to 15.3%, and the cells maintained 83% of their performance over 15 days, marking a major advancement in solar cell technology.



“Through this research, we could minimize surface defects on the quantum dots and stabilize their surfaces by newly adopting these amphiphilic ligands, thereby significantly improving the efficiency and stability of the solar cells,” explained Professor Jongmin Choi. He also noted the team’s intention to extend this approach to other photoelectric devices in the future.



This study, a collaborative effort by DGIST, Gyeongsang National University, and Kookmin University, was supported by the National Research Council of Science and Technology, the DGIST R and D Program, and the New Faculty Research Foundation at Gyeongsang National University. The findings were published in the ‘Chemical Engineering Journal’ on September 15, 2024.

Philippines’ Marcos opens first EV battery plant

Manila (AFP) Sept 30, 2024






President Ferdinand Marcos inaugurated on Monday the first factory for electric vehicle batteries in the Philippines, calling it the “future” of clean energy.

The Australian-owned lithium-iron-phosphate factory aims to produce two gigawatt-hours of batteries per year by 2030, powering about 18,000 electric vehicles or nearly half a million home battery systems.

“We have worked very hard and tried to do our best to bring this kind of technology to the Philippines with a clear recognition that this is the future,” Marcos said in a livestreamed speech.

“As the first manufacturing plant in the Philippines for advanced iron phosphate batteries… (it) sets the stage for the Philippines to become a player in clean energy storage in our part of the world.”

Located in New Clark city north of Manila, the StB Giga Factory Inc. facility will create 2,500 local jobs and channel five billion pesos ($89.2 million) into the economy each year, Marcos said.

The investment aligns with the government’s efforts to “transition our country to renewable energy”, and would help Manila “entice more investors in renewable energy facilities in the country”, he added.

Fire breaks out at Chinese battery giant CATL plant

by AFP Staff Writers

Beijing (AFP) Sept 29, 2024






A fire broke out Sunday at a factory belonging to Chinese battery giant CATL, which supplies electric vehicle makers including Tesla, but only a “relatively small” impact on operations is expected, the company said.

A CATL spokesperson said no injuries or casualties had occurred at the plant in the coastal city of Ningde, and that “the reasons behind this accident are still under investigation”.

Emergency services were sent to the plant to fight the fire and to organise the evacuation of any people who were inside the 15,000 square metre (160,000 square feet) site, a statement by the Dongqiao Economic and Technological Development Zone said.

Firefighters were alerted to the blaze just before 11:30 AM local time (0330 GMT).

It was not immediately clear what was produced at the plant, CATL’s base in the eastern province of Fujian, but the company said the effect of the now extinguished fire would not be significant.

“The impact to CATL’s overall production operation is relatively small,” the spokesperson said.

Videos published by the Chinese business media outlet Cailianshe, and posted on the Weibo social network, showed parts of a large white building in flames with thick gray smoke rising into the air.

AFP could not immediately verify the authenticity of the images.

CATL was founded in 2011 and produces more than a third of the electric vehicle batteries sold worldwide for automakers that include Mercedes-Benz, BMW, Volkswagen, Toyota, Honda and Hyundai.
