One, thermal runaway fault warning allocation list
1, the cell batteries temperature raises and causes thermal runaway alarm configuration table
The cell batteries temperature raises and causes that thermal runaway, the direct result of thermal runaway are shell bulge, the gas leakage of accumulator, and battery capacity descends, and loses efficacy at last.A kind of critical conditions that the thermal runaway standard definition takes place between the constant voltage charge period.At this moment, a kind of effect of mutual enhancing of accumulation takes place in the electric current of accumulator and temperature, and strengthens the damage that causes accumulator gradually.Rise with temperature, charging current increases, and is that electrolyte decomposition increases and the raising of the following sealed reaction efficient exercising result that complements each other that oxygen absorption reaction speed increases on negative plate at the amount of oxygen that produces on the positive plate.Follow the increase of reaction heat and charging current, when Joule heat generation speed during greater than the heat dissipation speed of accumulator, battery temp rises and surpasses environment temperature.Battery temp raises and causes that further charging current increases, and this causes that again battery temp raises.Like this, vicious cycle takes place.Finally cause thermal runaway.
The overheated harm of environment temperature mainly is 3 aspects: 1, inner pressure of battery is increased by force.2, make inside battery spare aging.3, electrolytic solution increases to the speed of battery outside diffusion.It is at high temperature aging that inside battery has many organism ratios to be easier to.Temperature is high more, spreads fast more.Electric current liquid has lacked internal resistance and will increase.
