How to prevent battery explosions?

    When the battery is charged to the end, after the two poles are converted into an effective substance, then continue to charge, a large amount of hydrogen, oxygen gas, H2: O2 is from 2: 1. Press hydrogen, oxygen-based electrolyte measuring, each charge 1ah, resulting in 0.4181L hydrogen and 0.20907L oxygen.   The explosive limit of the mixed gas of H2 and O2 is H2 accounted for 4-96% of the mixed gas volume. The explosion limit of H2 and air mixed gas is H2 4-74% of the mixed gas, and if the amount of electrolytic water of the charge is overcharged, the H2 content in the battery is in the explosion range.   The necessary conditions that cause the explosion are fire. If you encounter an open flame, you will explode. There will be a lot of fire in the car in the car, and the connecting card is loose arc; the electrical system short circuit forms a spark; maintenance machine Smoking, etc. Especially electrostatic generating sparks, etc.   There are many plastic material parts in modern automotive mouns. The dielectric constant is large, the resistivity is small, easy to generate and accumulate a large number of static charges, forming a quiethe, and the charge dissipates half-life in plastic machine, if it is not effective Eliminating, often leading to an important factor in electrostatic fire, a battery explosion, a light damage to the battery, heavy injury, and damage.   Prevention method is: (1) Control the amount of charge, but charging to reduce gas precipitation. The fire is strictly forbidden to ventilate.   (2) In charging, the wiring point should be secure, and the spark is not caused by loose.   (3) use low pressure constant pressure charging in use, and the amount is less.   ⑷ Prevent battery shell cracks, electrolyte osmosis.   ⑸ When the parking is disassembled, the battery should be detached after the air is retarded, and the negative pole line is removed. After the removal, the positive pole line is removed, and the battery is contrary to the battery, otherwise it is possible to produce the explosion of the battery.   ⑹ To keep the battery cover dry, clean.   ⑺ often check the battery Little Selide exhaust holes and keep the exhaust holes smooth.   ⑻ Control the liquid level of the battery to ensure that the liquid level is within the specified range, the electrolyte is not overflow.   ⑼ The battery terminal connecting wire should have a lower contact resistance and a larger contact pressure, and is applied to the connection to the external environment, prevent the generated spark to enter the battery, and ignite the combustible gas.
