This blog covers lead acid battery charging at low temperatures. A later blog will deal with lithium batteries. Charging lead acid batteries in cold (and indeed hot) weather needs special consideration, primarily due to the fact a higher charge voltage is required at low temperatures and a lower voltage at high temperatures.
Temperature Control: Ideally, lead-acid batteries should be charged at temperatures below 80°F (27°C). Charging at high temperatures can lead to thermal runaway, where the battery overheats and becomes damaged. If your battery becomes hot to the touch during charging, stop the process immediately and allow it to cool. 4. Avoiding Overcharging
Thus, under certain circumstances, it is possible to lower the temperature of the lead-acid battery during its discharging.
Material selection and preparation Considering the operation temperature range of lead-acid batteries (−10 to 40 °C), 40 # semi refined paraffin wax is selected as the phase change matrix, with phase change temperature of 39.6 °C and latent heat of 238.4 J/g.
Choosing the Right Charger for Lead-Acid Batteries The most important first step in charging a lead-acid battery is selecting the correct charger. Lead-acid batteries come in different types, including flooded (wet), absorbed glass mat (AGM), and gel batteries. Each type has specific charging requirements regarding voltage and current levels.
Thus, the maximum voltage reached determines the slope of the temperature rise in the lead-acid battery cell, and by a suitably chosen limiting voltage, it is possible to limit the danger of the “thermal runaway” effect.
