Abstract :
This paper presents results from experiments of high resolution mapping of the internal temperatures of valve-regulated lead-acid (VRLA) batteries on float duty. The internal thermal conditions of monoblock AGM VRLA batteries during different operating conditions have been characterised. The dynamic behaviour of the batteries during thermal runaway is reported. Changes of internal and external conditions leading to thermal runaway are discussed in terms of perturbation of the steady state conditions of the series-connected cells
