CATL launches MTB technology to support State Power Investment Corporation's Qiyuanxin power swap project

CATL announced that its pioneering MTB technology will first be applied to the battery swap project of State Power Investment Corporation Qiyuan Core Power and successfully implemented on its battery swap heavy-duty truck models. MTB technology, full name Module to Bracket, aims to integrate modules directly into vehicle brackets or chassis to improve space utilization and energy density. The technology is optimized for the two major challenges of heavy-duty trucks and construction machinery electrification-limited battery space and complex application environment. According to CATL, compared with the traditional battery pack + frame/chassis combination, the technology increases the system volume utilization by 40% and reduces the weight by 10%. In addition, by introducing U-shaped water cooling technology, the service life of the battery system has reached 10,000 times, which is twice that of similar products. The technology also supports power configurations from 140KWh to 600KWh, with a system energy density of 305Wh/L and 170Wh/kg to meet different usage needs. The technology realizes the feasibility of low-frame design, reduces the center of gravity of the whole vehicle by 21%, and can be used in a temperature range of -35°C to 65°C.
