CATL has introduced a new battery technology called MTB (Module to Bracket) for heavy duty electric trucks. According to CATL, MTB technology integrates the battery module directly into the vehicle's chassis, increasing battery system utilization by 40% and reducing weight by 10%.
Similar to CATL's Qilin battery for the passenger car market, the Chinese battery group is now showcasing a new battery solution for heavy electric trucks. In both cases, it is not the chemistry that is behind the innovation, but the structure of the battery. The Qilin battery is a cell-in-pack concept, while the truck battery is a module-bracket concept. In the latest solution, the direct installation of modules in the truck chassis not only increases system utilization and reduces weight, but also lowers the vehicle's center of gravity by 21 percent.
CATL also provides the following data: Battery packs with MTB technology can reach an energy density of 170 Wh/kg or 305 Wh/L, have a lifespan of 10 years or 10,000 cycles, and support capacities from 140 to 600 kWh. The company specifies an operating temperature range of -35 to 65 degrees Celsius.
Unlike the cell-in-pack battery that will be used for the first time in the Zeekr 009 as standard from 2023, the CATL combines truck MTB technology with a battery replacement system. In any case, the company emphasizes that the solution is suitable for the electrification of trucks and construction equipment, which can be equipped with replaceable batteries.
