Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of batteries and electric power, and particularly relates to a storage battery activating liquid for a substation, an activating method and an activated barbecue vehicle, and the barbecue vehicle is particularly suitable for holiday barbecue vehicles. BACKGROUND

[0002] Generally, the returned storage battery is repaired again by adding distilled water, so that the recovery index of repairing damaged plates cannot be achieved, resulting in that the use requirement cannot be met and the storage battery is discarded. At present, power generation, power transformation and power supply units in China are all equipped with storage battery equipment of corresponding voltage grades, and the returned storage battery is not considered to be repaired, recovered and reused, but is directly discarded, resulting in a large amount of waste. At the same time, the discarded storage battery does not reach the standard operation period, and the service life of the operated storage battery is difficult to improve due to the lack of effective activating liquid repair. When the battery is charged, lead sulfate cannot be self-dissolved and effectively subjected to oxidation-reduction reaction. When the C10 discharge rate is reached, the terminal voltage drops rapidly, and generally drops to about 1.8 volts in 1-2 hours. When charged, the terminal voltage rises rapidly, and the voltage is as high as about 2.9 volts. After "sulfation", the internal resistance of the battery increases, and the temperature rises rapidly when charged.
