This white paper, Understanding Battery Management Systems (BMS): Key Components and Functions, by Eaton, outlines the essential components and functions of BMS.
These systems ensure battery safety and efficiency by regulating charging, preventing faults and optimizing energy use. The BMS uses sensors and communication interfaces for real-time diagnostics. These features extend battery life, reduce failures, and support applications like EVs and energy storage.
Battery data specialist Moba has launched a Diagnostic Trouble Codes (DTC) report that’s designed to provide dealers, remarketers and fleet operators with information about an EV’s fault codes alongside battery health data.
The report retrieves and explains a vehicle’s fault codes using the same Moba dongle and workflow as the company’s existing battery diagnostics.
Moba provides a State of Health (SoH) assessment based on official manufacturer data, giving buyers verifiable information about battery condition.
Battery health is a key consideration when assessing an EV, but a vehicle’s value also depends on the condition of its other systems. Moba’s new DTC report covers three groups of systems: batteries and high-voltage components; electric powertrains and charging systems; and safety systems, including braking, steering, airbags and driver assistance. Each code identifies the system involved and includes a plain-language description.
Moba also provides battery analysis from individual cells to complete systems. The analysis detects faulty cells and balancing issues, estimates remaining real-world driving range and identifies when rebalancing or replacement may be needed.
The DTC report is integrated with Moba’s existing EV diagnostic process. The procedure takes approximately one minute, is guided through the mobile application and requires no additional hardware. Each diagnostic generates a certificate, a detailed battery report and a DTC report.
“Our customers have always asked us one question: Can I trust this battery?” said Moba CEO and co-founder Guillaume Hébert. “With the Fault Codes (DTC) report, we answer the next one: Can I trust this car, particularly the reliability of the other electric powertrain components, such as the inverter, onboard charger, DC/DC converter and electric motor?”
Lithuanian capital Vilnius will deploy up to 161 new electrified buses and related charging infrastructure, supported by a €110-million financing package from the European Investment Bank (EIB) and the Council of Europe Development Bank (CEB).
VVT will use the EIB and CEB loans to help finance new electric and hydrogen buses, 145 charging stations and upgrades to existing depots, replacing older diesel and liquefied petroleum gas vehicles. The project is scheduled for completion by the end of 2027.
Meanwhile, the European Bank for Reconstruction and Development (EBRD) and Nordic Investment Bank (NIB) are supporting the renewal of the city’s trolleybus fleet.
“Vilnius is showing how European cities can turn climate ambition into tangible improvements for citizens,” said EIB Vice President Karl Nehammer. “We are helping deliver cleaner buses, better public transport and healthier urban environments.”
“This financing enables us to carry out one of the most ambitious public transport modernization programs in VVT’s history,” said VVT CEO Ignas Degutis. “Together, we are investing in 161 zero-emission buses and the infrastructure needed to operate them reliably, creating cleaner, quieter and more comfortable journeys for Vilnius residents.”
EV charging provider Roam has secured a contract to install charging infrastructure at 14 UK hotels owned by ProsperCap. Installation began in September.
The project will include 170 EV charging sockets: 158 22-kilowatt sockets and 12 50-kilowatt sockets. Overnight guests can use the lower-powered sockets while visitors who need to recharge more quickly can use the 50-kilowatt units.
“Different hotel users have different charging requirements, from overnight guests who have several hours available to visitors who need to recharge more quickly,” said James Randall, CEO of Roam. “Hotel charging networks need to accommodate both.”
The project will be delivered through Roam’s fully funded EV charging model, which allows participating hotels to install charging infrastructure without significant upfront capital investment.
“Hospitality is an important part of the UK’s charging infrastructure,” said Randall. “For many drivers, being able to charge their vehicle while they sleep, eat, attend a meeting or spend time at a hotel is more convenient than making a separate charging stop during their journey.”
“A growing number of our guests now travel in EVs, and reliable charging is an increasingly important part of the experience they expect from our hotels,” said Weerachai Amornrat-Tana, Acting CEO of ProsperCap. “Because all the electricity used at our hotels is sourced through renewable energy contracts, guests can charge their vehicles knowing their journeys are lower-carbon.”
Was BP ever serious about its “beyond petroleum” marketing slogan? It’s too early to say, but in July 2025, the oil giant decided to get out of the fleet EV charging market, leaving former customers unplugged, so to speak. Fortunately, other companies stepped in to help former bp pulse corporate customers migrate to new platforms.
Fuuse and Drax Electric Vehicles, part of energy provider Drax Group, have announced a partnership to support the transition of nearly 1,000 former bp pulse fleet depot-charging customers, which collectively operate more than 14,000 charging sockets.
Fuuse will lead the migration of the charging infrastructure to its platform, allowing fleets to retain and manage their existing charging equipment.
The partnership follows more than a year of hardware testing and platform development between bp’s EV charging business and Fuuse to prepare customers for the transition. Fuuse’s onboarding team will assess each customer’s charging infrastructure requirements, confirm service arrangements and guide customers through the migration process.
Through its partnership with Drax, Fuuse will provide customers with access to service and maintenance support. This includes continued support for existing hardware warranties and maintenance of previously installed charging infrastructure.
“Being selected as the migration partner reflects the work of our team and the capabilities of our platform,” said James Chapman, Strategic Sales Director at Fuuse. “Through our existing partnership with Drax, we can also provide hardware maintenance support while honoring existing warranties. This is about more than software. It’s about protecting customer investments, maintaining operational continuity and making the transition straightforward.”
“Ensuring former bp pulse fleet depot-charging customers can move forward with confidence is our priority,” said Adam Hall, Energy Services Director at Drax Electric Vehicles. “With nationwide field service capabilities and continued hardware warranty support, we can help keep charging infrastructure maintained, supported and operational.”
Battery supplier Electrovaya has entered into a strategic supply agreement with Janus Electric Holdings, an Australian developer of diesel-to-electric conversion and battery-swapping systems for Class 8 heavy-duty trucks.
Janus has placed around $26 million in initial purchase orders for Electrovaya’s battery systems to meet demand for Janus products in the US and Canada. Electrovaya has also agreed to invest approximately $1.4 million in Janus stock.
Janus converts existing diesel trucks to battery-electric operation and pairs them with swappable battery packs and Janus Charge & Change Stations, allowing fleets to exchange batteries in minutes, and to electrify without the capital cost of purchasing new trucks.
The companies explain that Electrovaya’s battery systems, which incorporate its proprietary Infinity Battery Technology and are designed for safety, reliability and long cycle life in high-utilization applications, are well suited to the repeated daily swap cycles of this model. Approximately 600 kWh of battery capacity is installed for each truck conversion.
To date, Janus has secured orders and commitments for 118 truck conversions in the United States and Canada. In Australia, Janus continues to serve existing customers and is advancing a pipeline of opportunities across the mining, linehaul and quarry sectors.
Electrovaya is now supplying battery systems to support the start of Janus’s North American customer deployments. Electrovaya is expanding manufacturing capacity at its facility in Jamestown, New York, which is expected to come online during the company’s 2027 fiscal year.
“Electrovaya is an important partner to Janus Electric, and we’re particularly pleased it has decided to invest directly in our business,” said Ben Hutt, Managing Director and CEO of Janus Electric. “Reliable battery supply is critical to our growth, and Electrovaya’s expanding North American manufacturing capabilities will be important as we scale.”
“Class 8 trucking is one of the most exciting and demanding frontiers in electrification, and Janus has demonstrated real commercial traction with fleets in the US, Canada and Australia,” said Dr. Raj Das Gupta, CEO of Electrovaya. “Janus has developed a practical solution to one of the major challenges facing heavy transport, enabling diesel-powered trucks to be converted to electric without compromising their commercial operations.”
LG Energy Solution subsidiary NextStar Energy has produced 10 million battery cells at its plant in Windsor, Ontario, since commercial production began in November 2025.
