Abstract
The invention discloses a method for formation of a colloid storage battery of an electric vehicle. The method aims at solving the problem that formation time of a colloid storage battery of an electric vehicle is long and thus a production period is long. The method comprises multiple charging and discharging steps and two vacuum-pumping steps. A first vacuum-pumping step comprises standing a storage battery loaded with a mixed acid solution for 0.5 hours and carrying out first vacuum-pumping for 5 to 8 seconds, wherein a vacuum degree is in a range of 0.06 to 0.08MPa. After two charging steps and a discharging step, a second vacuum-pumping step is carried out for 2 to 5 seconds, wherein a vacuum degree is in a range of 0.06 to 0.08Mpa. Because of addition of the two vacuum-pumping steps, the method guarantees that a colloid solution can be mixed fully in a storage battery. Through control of a water temperature in processes and a routing inspection system adopting voltage, the method guarantees consistency of a storage battery. Compared with formation time of the prior art, formation time of the method is shorten about 6 hours shorter. Therefore, the method saves energy consumption and improves production efficiency greatly.
