Client Challenge – Power Stability for Continuous HVAC Connectivity
A U.S.-based smart home HVAC manufacturer faced critical challenges with its smart thermostat battery system. The devices required continuous WiFi connectivity for real-time temperature control and energy optimization. However, frequent power instability caused system resets and data interruptions. In addition, compact wall-mounted designs limited battery size and capacity. Moreover, standby power consumption from wireless modules increased energy drain. Therefore, the client needed a reliable, compact, and long-life smart thermostat battery solution.
Our Solution – Low-Power Lithium Battery with Smart Energy Management
To solve these issues, Himax Electronics developed a custom smart thermostat battery solution. First, we designed a high-efficiency lithium battery with ultra-low self-discharge to support long standby operation. Next, we integrated a smart BMS to stabilize voltage output during WiFi transmission peaks. In addition, we optimized energy distribution for HVAC control cycles. As a result, the battery ensured stable performance, continuous connectivity, and efficient power usage in smart home environments.
Results & Benefits – Stable Connectivity and Improved Energy Efficiency
With the new smart thermostat battery solution, the client achieved significant improvements. Device stability increased, eliminating unexpected system resets. Furthermore, continuous WiFi connectivity enabled accurate real-time temperature control and energy optimization. The compact battery design allowed seamless integration into slim wall-mounted thermostats. As a result, the client improved user experience, reduced energy waste, and strengthened competitiveness in the smart home HVAC market.
