Temperature effects are discussed in detail. The consequences of high heat impact into the lead-acid battery may vary for different battery technologies: While grid corrosion is often a dominant factor for flooded lead-acid batteries, water loss may be an additional influence factor for valve-regulated lead-acid batteries.
Batteries generate heat during the charging process due to internal resistance and inefficiencies. While a certain amount of heat is normal, excessive temperatures can lead to potential safety hazards and damage the battery’s overall lifespan.
Two heat effects are to be considered when charging or discharging a lead-acid battery: the entropy effect (reversible heat effect, − T Δ S) and the Joule effect , . In most cases, the entropy effect is dominated by the Joule effect from high charging and discharging currents in automotive applications (cf. Table 1 ).
Charging in hot environments can cause your battery to heat up more quickly, so it’s best to charge batteries in a cool and well-ventilated area. 3. Battery Age: As batteries age, their internal resistance may increase, causing them to generate more heat during charging.
The aim of this study is to look at a less appreciated fact that during lead-acid battery discharge, an entropy-based phenomenon leads to a cooling effect, which may not be intuitively apparent as it is often negated by Joule heating due to large current flow.
Heat is generated on recharge, float charge and discharge. The heat generated on charge is finite, i.e. once the battery is fully charged no more heat is generated but at this point the battery enters the float charge phase and as long as the battery is on charge, heat is being generated.
