6 FAQs about [Heating of lead-acid battery terminals]
How does heat affect a lead-acid battery?
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.
What is the entropy and Joule effect of a lead-acid battery?
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 ).
How do thermal events affect lead-acid batteries?
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as “thermal runaway.”
What are the different types of terminal construction for lead-acid batteries?
Terminal construction for lead-acid batteries can be generally categorized into two types; those which are a solid lead alloy and those utilizing a lead alloy terminal with a copper insert. Copper inserts are commonly used in batteries designed for high rate discharges. Such terminal design reduces connection resistance.
Is there a cooling component in a lead-acid battery system?
It was found by calculations and measurements that there is a cooling component in the lead-acid battery system which is caused by the endothermic discharge reactions and electrolysis of water during charging, related to entropy change contribution.
What are the main functions of lead-acid batteries?
