Advanced low-voltage battery solutions provider
link hidden, please login to view, announced a strategic investment in Altris, a pioneer in sustainable sodium-ion battery technology, with the aim of manufacturing low-voltage, sodium-ion (Na-ion) batteries for the automotive sector.
link hidden, please login to view expects its investment to initially enable Altris to finalize and start pilot production of Na-ion automotive batteries, followed by commercial production beginning in 2026. This equity stake builds on a joint development agreement (JDA) between Clarios, producer of one in three of the world’s low-voltage car batteries, and Altris, a leader in sodium-ion cathode material and battery cell technology, focused on low-voltage Na-ion batteries, according to a news release announcing the strategic investment.
Clarios said it will leverage its expertise in Battery Management Systems (BMS), software and system integration to design the Na-ion low-voltage automotive battery system to optimize battery performance.
Altris, on the other hand, will focus on developing the sodium-ion cell technology for this low-voltage application. Every vehicle, including hybrid electric and fully electric vehicles, requires a low-voltage energy source to power an increased number of software-based functions such as steer-by-wire, break-by-wire, autonomous functions, and enhanced in cabin experiences.
The Clarios low-voltage system architecture, comprising multiple networks and battery power sources, is essential for powering critical safety features and ensuring redundancy in vehicle electrical systems, the company said. Sodium-ion batteries are well suited to meet these increased power demands. At the same time, they are inherently sustainable and easy to recycle.
“A sodium-ion battery solution perfectly complements our chemistry-agnostic portfolio, neatly dovetailing with lithium-ion and lead-acid options to capture the best attributes of both: high performance and lower cost,” said Federico Morales-Zimmermann vice president and general manager, global OEM customers and technology at Clarios. “A sodium-ion battery system provides agility for automakers seeking options in meeting intensifying low-voltage demands created by advanced vehicle technologies.”
The materials used to produce sodium-ion cells – salt, wood, iron and those found in air – are abundant globally and are free from harmful chemicals or minerals mined in conflict zones. Developing Na-ion batteries for vehicles would represent an important advancement in automotive battery technology, while advancing the auto industry’s circularity goals, Clarios said.

Hybrid vehicles place greater stress on belts and tensioners due to their dual-mode systems. Specialized hybrid tensioners are engineered to handle varying torque demands and ensure optimal belt performance during rapid transitions between electric and gasoline modes, reducing wear and improving efficiency.

Although hybrids have been around for more than 20 years, many shops are not familiar with the risks of high-voltage vehicles or are not comfortable working on or around them. To address this concern, the National Institute for
link hidden, please login to view (ASE) said it is offering a testing and certification program for electrified propulsion vehicle (xEV) high-voltage safety, including light-duty and medium-/heavy-duty hybrid and electric vehicles. This industry-developed program provides two options to certify shop personnel based on their involvement with xEVs. Industry standards accompany both certifications and are intended to be used in conjunction with high-voltage vehicle safety training. Training managers have found that technicians who have attained xEV certification have increased confidence and lower anxiety while working on hybrid and electric vehicles.
The test can be completed online, ASE said. Once the test is passed, the test-taker receives an electronic credential and a certificate that can be downloaded and printed for display.
The xEV Electrical Safety Awareness Certification (Level One) certification is designed for anyone who may encounter xEV in the workplace, including individuals who perform tasks near electric-powered vehicles, such as sales, service, repair and support, ASE said. Level One individuals require high-voltage electrical safety awareness to identify the hazards and reduce the associated risks when working on or near xEVs or near high-voltage components of electrified propulsion vehicles.
Skills performed by Level One individuals may include: operating (driving) a hybrid or electric propulsion vehicle; performing maintenance and repairs not related to high-voltage systems or their components; handling non-high-voltage components of electrified propulsion vehicles and working near electric-powered vehicles or high-voltage components of electrified propulsion vehicles.
The xEV Technician Electrical Safety Certification (Level Two) certification is for those service professionals, technicians or specialists who have received high-voltage electrical training; have demonstrated skills and knowledge related to the construction, operation and repair of electrically powered high-voltage vehicles; maintain an electrically safe working area and use required personal protective equipment. They have also received safety training to identify the hazards and reduce the associated risk.
Skills performed by Level Two repair professionals may include: evaluating and classifying the condition of the high-voltage battery and high-voltage electrical system; isolating the voltage from the high-voltage systems and checking the isolation from the supply; securing the high-voltage system against being activated; re-starting the high voltage system; performing general work on de-energized high-voltage systems and components and assessing the risk of high-voltage vehicles that were involved in an accident.
“Today, shops must consider the exposure and liability related to servicing hybrid and electric vehicles,” Dave Johnson, ASE president and CEO, said. “The ASE xEV certifications should be a critical component of a shop’s high voltage safety training. The standards were developed to keep shop personnel safe and earning the credentials is a great way for shops to showcase the ability of their knowledgeable staff to work on high voltage vehicles.”
