Nio promises its new typical array 75kWh hybrid mobile battery will decrease the array loss in low temperatures by twenty five%.
Applying its patented systems, the new battery delivers equally a for a longer period array in cold temperature and much more correct point out of charge (SoC) estimation while matching the battery overall performance of a ternary lithium battery.
This new typical array battery (75kWh) is a hybrid of ternary lithium and lithium iron phosphate (LFP) cells employing new era mobile to pack (CTP) know-how.
To accomplish the array peformance get, engineers intended a comprehensive thermal management software package and components system for the battery. The hybrid structure of ternary lithium cells and LFP cells make total use of the low temperature overall performance benefit of such cells to make improvements to the total battery overall performance.
A dual chemistry handle algorithm exactly controls the overall performance of ternary lithium and LFP cells in cold temperature to make improvements to vitality performance. In addition, a radiant thermal payment heater uniformly heats the cells to maintain the doing the job temperature of the battery when taking into account the vitality consumption.
Further gains in passive thermal insulation were being reached employing low thermal conductivity supplies and an innovative structural layout. The outcome was a reduction in array loss by twenty five% when compared to its LFP counterpart in low temperature environments.
The self formulated hybrid mobile battery SoC estimation system integrates improvements in equally software package algorithm and components to decrease estimation faults to fewer than three%, thus reaching the level of ternary lithium battery SoC estimation. The dual chemistry SoC algorithm normally takes benefit of ternary lithium and LFP battery units to promise precision. A large-electric power DCDC inside the battery makes certain rapid, true time and well balanced SoC calibration.
CTP know-how simplifies manufacturing and assembly by ten%, increases volume utilisation by 55, and increases vitality density by 14% to 142Wh/kg.
The typical and extended-array ternary lithium battery (100kWh) are now out there for new automobile orders with deliveries set for November.
Motor vehicle price ranges with the new 75kWh battery are the similar as for the preceding 70kWh battery.
