             abstract = "The supply of electrical power is one of the most important 
                         functions required by the diverse payloads of satellites. A fault 
                         in the corresponding subsystem might lead to mission or even 
                         vehicle loss. Among the causes of such faults, we highlight the 
                         phenomenon of thermal avalanche in batteries. It can be explained 
                         as an energetic unbalance where the rate of heat generated in the 
                         interior of the system exceeds its capacity to dissipate it. This 
                         occurred to the OAO1 of NASA just after its launch on April 8, 
                         1966; and with the CBERS2 of CAST and INPE already in orbit in 
                         2007 and 2009. This work presents a discussion on the causes and 
                         eects of thermal avalanches in articial satellite battery charging 
                         and discharging systems. To do so it: 1) revises the literature on 
                         the known causes and eects; 2) develops a block diagram model for 
                         a battery charging and discharging system in articial satellites, 
                         based on macroscopic principles which can be generalized to a wide 
                         variety of topologies and technologies of power supply and 
                         batteries; 3) discusses new causes and eects. Such discussion 
                         allows: 1) explains the thermal avalanche occurred to OAO1 and 
                         CBERS2; 2) estimate whether this will occur or not to other 
                         similar satellites as the CBERS3e4.",
