As far as we know, all EVs in production by major automakers use a conventional lead-acid battery for the 12 V system (surprising, but true – more on why in a bit) and this battery needs charging, just as it does in an ICE vehicle. While you could hang an alternator off the traction motor… Read more »

LeasePlan and Allego offer new home-to-office charging service
Car sharing firm LeasePlan and charging solution provider Allego have announced a new partnership to provide LeasePlan EV customers with access to personal chargers at home and at work. The charge points are designed to enable drivers to be automatically reimbursed for load balancing services provided to utilities. The scheme will initially be rolled out… Read more »
China’s Shanghai Energy plans a massive increase in battery separator production
China is steadily positioning itself at the forefront of Li-on battery production. One sign of this is a massive ramp-up of the production of wet-process separators (separators are a critical component of Li-on batteries – they keep the anode and cathode from touching, while allowing ions to pass through). Shanghai Energy has announced that it… Read more »
Chinese companies increasing their pursuit of lithium resources
A recent report from metals and minerals research firm Roskill details how China is quickly working to increase its control of the lithium supply chain to support the rapid growth of its lithium-ion battery industry. The report provides examples of several major players who have recently announced or completed acquisitions. CATL, one of China’s largest… Read more »
Saft joins forces with European partners to develop advanced Li-ion and solid-state tech
Battery manufacturer Saft, a subsidiary of oil giant Total, has announced that it will join forces with a handful of European partners to form a development R&D partnership focused on creating cutting-edge batteries. Saft CEO Ghislain Lescuyer recognizes that “batteries are at the heart of the current technological revolution. Their development and production play a… Read more »
Adding graphene girders to silicon electrodes could double battery life
Graphite has long been the default choice of material for anodes, but researchers dream of replacing graphite with silicon, which has ten times the gravimetric energy density. Unfortunately, silicon has several issues that limit its commercial use – it expands during lithiation, causing particles to agglomerate in ways that impede efficiency, and it is not… Read more »
Delta-Q expands family of lithium battery chargers for EVs and industrial machines
Delta-Q Technologies has introduced a new addition to its family of lithium battery chargers. The new ICL900 is a 900 W charger, designed to charge battery systems of any lithium-ion chemistry from 9 to 15 cells in series. The new charger is suitable for use on any electric machine, including scooters, floor care machines, lift… Read more »
GM and Fiat Chrysler hit with lawsuits over diesel cheating software
We may not have heard the last of the dirty diesel scandal. Two of the Big Three automakers have recently been served with lawsuits alleging behavior similar to that which may end up costing VW $20 billion. The US Justice Department has filed a civil complaint on behalf of the EPA, claiming that Fiat Chrysler… Read more »
Southwest Research Institute consortium conducts independent battery benchmarking
Comparing the spec sheets from different parts manufacturers is tricky business for engineers in any industry. However, the advanced battery market seems to be uniquely challenged in this regard. As Tesla CEO Elon Musk often points out, when it comes to batteries, the BS factor is outrageous. Even if you assume that every vendor provides… Read more »
Seaworthy EVs: Leclanché designs and manufactures Li-ion cells and systems
The advantages of electrifying transportation are far-reaching. Advanced energy storage systems are even making their way into the commercial marine industry. There are many marine applications in which adding a large Li-ion battery pack makes a lot of sense. The best-use case varies depending on the boat size and purpose. All-electric ferries, for example, are… Read more »
