Industrial machinery operating outdoors, in unheated logistics facilities, or in cold-storage environments faces severe operational hurdles. Low ambient temperatures induce reduced battery output, increased internal resistance, and restricted charging capabilities-directly impacting equipment startup, available runtime, and fleet availability.
Denergon's 60V low-temperature lithium battery platform provides a robust, customizable DC power source designed for mobile and stationary industrial applications exposed to sub-zero conditions.

FAQ
Q: How much capacity does a 60V low-temperature lithium battery lose when discharging at -20°C?
A: Low-temperature capacity retention depends on the specific cell chemistry, discharge C-rate, and cold exposure duration. Typically, specialized low-temperature cells retain roughly 70% to 85% of their room-temperature rated capacity at -20°C. Request specific discharge curves and voltage-under-load graphs for your evaluation.
Q: Why can't standard lithium batteries be charged below 0°C without risk?
A: Charging ordinary lithium-ion cells at sub-zero temperatures causes lithium ions to deposit onto the graphite anode as metallic lithium plating instead of intercalating. This results in permanent capacity loss and can puncture the separator, risking internal short circuits. Proper cold-temperature charging requires integrated heating systems or specialized charge-inhibition firmware.
Q: What factors must be checked when replacing a lead-acid setup with a 60V lithium pack?
A: Matching nominal voltage alone is insufficient. You must verify the charger's voltage output profile, continuous and peak current limits, physical dimensions, connector layouts, and BMS communication protocols to ensure seamless integration with the equipment's electronic control unit (ECU).
Q: What communication protocols are supported by the 60V platform?
A: Standard BMS configurations support CAN2.0, RS485, and UART interfaces to transmit real-time telemetry (voltage, current, SOC, temperature, and fault alerts) to the host system. Custom industrial protocols like CANopen can also be implemented via ODM customization.
