![]() ![]() is now using CATL’s LFP batteries for its Model 3 electric car sold in the Chinese market due to their lower cost, said CSI, which could be an early indicator that more LFP batteries will find their way into passenger cars. ![]() The company said its cell-to-pack (CTP) technology, as compared to the traditional method of placing cells in modules and then packs, decreases the parts count and can today achieve an energy density of 160 Wh/kg, the same as the Tesla Model 3 NCA (nickel cobalt aluminum) battery pack. The coulomb (symbolized as C) is a standard unit of electric charge in the International System of Units (SI). CATL’s standard LFP cells are capable of 4000 100% DoD (depth-of-discharge) 1C charge/1C discharge cycles and its super long life or “million-mile” technology is capable of 12,000 cycles. We can set that up.”Ĭompared to passenger vehicles, the application requirements and work conditions can be more complicated in commercial vehicle electrification and include a range of equipment such as city buses, trucks, vans as well as forklifts, locomotives and construction equipment.ĬATL’s battery solutions include lithium-iron phosphate (LFP) chemistry - an extremely popular choice for buses in China - that feature a long cycle life and high thermal runaway stability up to 800☌. For instance, in the transit bus industry they have a ‘get off the railroad switch,’ so no matter the problem, if that bus is stuck on the railroad and the driver pushes the override switch, it needs to go. Much of the opportunity for customization centers around operator interface, and “those are easy settings we can put in to adapt to whatever our customer’s preferences are,” he said. We can get these battery systems up and running in a prototype truck in a week, or two at the most.” “Because we have so many of these battery systems on the road, and because between CATL and CSI we have worked with so many different vehicle manufacturers, we’ve been able to make it so the interface to the vehicle OEM is relatively simple. ![]() “We now have a suite of customers,” said Mazaika, and while unable to disclose them by name, “they include major truck manufacturers, large system integrators and other component manufacturers.” He said COVID-19 has slowed the progress on some significant projects that will soon be made public. Today, CSI provides electrification solutions for commercial vehicles that can include advanced lithium-ion batteries as well as accessory systems such as cabin heating, battery cooling systems, electric air conditioning compressors, dc/dc converters, on-board chargers, electric steering pumps and electric air compressors for braking. The Livermore, Calif.-based company is named after Charles de Coulomb, a French physicist who made important discoveries in electricity and magnetism. In early 2019, CSI signed a long-term partnership with CATL, becoming a wholesale distributor and service center for its commercial vehicle battery systems in North America. My goal was to bring the over the high-volume, high-quality manufactured products that were available in China to really enable the whole electrification of commercial trucking in North America. These have given them unparalleled experience, having traveled over 25.7 billion miles. “They’ve already got 270,000 commercial trucks and buses on the road using CATL batteries. “The CATL product has been out there for about eight years, and they’ve got high-volume manufacturing lines in place,” said Mazaika. Since then, one of its focuses has been reducing the cost of its batteries. Based in Ningde in the country’s Fujian Province, CATL was founded in 2011 as a spinoff from a major supplier of batteries for consumer products. (CATL), one of the largest motive power battery designers and manufacturers in China. Mazaika reached out to Contemporary Amperex Technology Co. The biggest contributor to the higher costs was the batteries.” They’re being sold in relatively small numbers and it was slow to go mainstream. As a result, fleets will buy in small numbers, maybe five or 10 vehicles - a really big fleet might buy 50. “But the biggest challenge has always been that the cost of the commercial vehicles can’t meet the total cost of ownership goals the fleets have. “A lot of really good EV products have come out over the past five to ten years,” said Mazaika. (CSI) two years ago to work with original equipment manufacturers to help develop and manufacture reliable and affordable battery-electric commercial vehicles. To help fulfill that vision, he founded Coulomb Solutions Inc. ![]() David Mazaika saw an opportunity based on his 20 years of experience in the heavy-duty commercial vehicle space. ![]()
