Core Insights - LiTime has developed LiHeat™, a patented dual-mode self-heating technology that enables lithium batteries to charge in freezing temperatures, addressing a significant challenge for users in cold environments [2][13]. Technology Overview - Traditional self-heating lithium batteries rely on plug-in heating, where an external charger powers the heating element until a safe charging temperature is reached [3]. - LiHeat™ introduces self-powered heating, allowing the battery to use its own stored energy to warm the cells before connecting to an external charger, enabling immediate charging once connected [4]. - The system features automatic mode switching, transitioning from self-heating to plug-in heating if necessary, enhancing thermal management for cold-weather applications [5]. User Benefits - Users can activate the self-heating function remotely via the LiTime Bluetooth app when temperatures are above -20°C and the battery's state of charge is above 20%, allowing for pre-heating before charging [7]. - This feature is particularly beneficial for winter solar applications, ensuring that solar energy is captured efficiently on cold mornings [8]. Product Integration - LiTime is integrating LiHeat™ technology into various lithium battery models, targeting cold-weather uses such as RV camping, off-grid solar systems, and outdoor expeditions [10]. - The company plans to offer additional LiHeat™ batteries with more voltage and capacity options, all equipped with Bluetooth-enabled BMS systems for user monitoring and management [11]. Market Demand - As energy storage systems expand into outdoor and extreme-climate applications, the demand for batteries capable of cold-weather operation is increasing [13].
