Contemporary Amperex Technology Co. Limited (CATL) will supply lithium iron phosphate (LFP) batteries equipped with novel Cell-to-Pack (CTP) technology to Solaris to power its bus models in a bid to facilitate bus electrification.
CATL’s LFP battery system features exceptionally long battery life and high thermal stability. By removing the conventional module packaging, the CTP technology increases the battery energy density and payload of the e-bus, making it a good option for sustainable city transportation.
CATL’s CTP technology has increased the volumetric utilization efficiency of the battery pack, which has increased from 55% for the first-generation CTP battery to 67% for the third generation, or Qilin battery. The energy density of NMC Qilin battery can reach 250 Wh/kg, while that of LFP Qilin battery can reach 160 Wh/kg.
Headquartered in Bolechowo, Poland, Solaris is one of the leading European bus and trolleybus manufacturers. It ranked first in the zero-emission bus market in 2021 in Europe. Starting co-operation with CATL, Solaris will extend its offer by new battery solutions available in its vehicles.
This co-operation will extend CATL’s global commercial vehicle electrification network and accelerate the electrification transition of commercial vehicles worldwide.
