Battery Thermal Management System (Request for Technical Transparency)

To the Leapmotor Engineering and Support Team, As owners and enthusiasts of Leapmotor vehicles, we are formally requesting the publication of a detailed technical brief regarding the battery thermal management system. Current documentation lacks the specifics necessary for users to optimize vehicle performance and battery longevity in cold climates. To eliminate ambiguity, we request clarification on the following points: "Battery Pre-heating" Logic and Functionality Activation Thresholds: What are the specific ambient and internal battery temperature thresholds (°C) required for the pre-heating function to engage? App Commands: When the "Battery Heating" icon is activated in the mobile app, what is the system's target? Does it aim for an optimal driving temperature (e.g., 10–15°C) or an optimal DC fast-charging temperature (e.g., 25–30°C)? Duration: What is the estimated time required to reach a safe operating temperature when starting from an ambient temperature of 0°C? Cold Weather Charging Safety Cold-Start Charging: Does the BMS (Battery Management System) automatically and safely throttle charging speeds to prevent lithium plating/degradation when the battery is cold, or is the user required to manually pre-heat the battery to ensure long-term health? Power Sourcing: Does the pre-heating function draw power exclusively from the grid (when plugged in), or can it utilize the internal battery's energy while parked? Target Parameters and Automation What is the specific target temperature (°C) the system maintains during pre-heating versus during active driving? Does the vehicle support automatic thermal pre-conditioning when a DC fast-charger is set as a destination in the onboard navigation system? Rationale Currently, the user community relies on guesswork and anecdotal evidence. This lack of clarity leads to inefficient energy use and unnecessary concerns regarding battery health. Providing clear, transparent technical data will not only enhance the user experience but also solidify Leapmotor’s reputation as a technologically advanced and customer-centric manufacturer.
