Litime Introduces Liheattm, The Industry-First Dual-Mode Self-Heating Technology For Lithium Battery Charging In Cold Weather

From Passive Heating to Intelligent Thermal Management

Traditional self-heating lithium battery designs typically rely on a single heating method known as plug-in heating, where an external charger powers the heating element until the battery reaches a safe charging temperature.

LiHeatTM adds a second capability: self-powered heating. In cold environments, the battery can use its own stored energy to warm the cells before connecting to an external charger. As a result, charging can begin immediately once the charger is connected, instead of waiting for the battery to heat up.

The system also supports automatic mode switching. If self-heating alone cannot bring the battery to the required temperature, LiHeatTM automatically transitions to plug-in heating, using external power to continue warming the cells until safe charging conditions are reached.

Together, these two modes transform conventional heating from a passive process into a more intelligent and flexible thermal management system - particularly for cold-weather lithium battery applications.

Pre-Heating Before Charging Saves Time - and Solar Energy

Through the LiTime Bluetooth app, users can remotely activate the self-heating function when ambient temperatures are above -20°C and the battery's state of charge is above 20%. This allows the battery to warm up in advance, enabling charging to start immediately once a power source is connected.

The feature can be particularly valuable in winter solar applications. On cold mornings when solar panels begin generating power, batteries equipped with LiHeatTM can reach a chargeable state faster, helping ensure that solar energy is captured instead of lost due to temperature restrictions.

Expanding Across LiTime's Product Line

LiTime has begun integrating LiHeatTM technology into several lithium battery models in its self-heating battery lineup, including:

• 12V 100Ah Group24 Self-Heating Battery
• 12V 165Ah Self-Heating Battery
• 12V 320Ah Mini Self-Heating Battery
• 24V 230Ah Self-Heating Battery

These products are ideal for cold-weather uses such as winter RV camping, off-grid solar systems, ice fishing gear, and outdoor expeditions in extreme conditions, delivering reliable power in low temperatures.

The company says additional LiHeatTM batteries with more voltage and capacity options are planned. All models include Bluetooth-enabled BMS systems that allow users to monitor temperature, adjust heating modes, and manage battery settings through the LiTime app.

As energy storage systems increasingly move into outdoor, high-latitude, and extreme-climate applications, the demand for batteries for cold-weather operation continues to grow.

LiTime says LiHeatTM represents a step forward in battery thermal management, designed to deliver dependable charging and stable performance even in sub-zero environments.
