Nowadays, when it comes to China lithium ion forklift battery, I believe we have heard of it more or less, but we may not know much about some specific knowledge of China lithium ion forklift battery, so I will introduce it to you below. Common explosion-proof knowledge about China lithium ion forklift battery.

China lithium ion forklift battery

   1. Conditions for flammable gas explosion

  1. Internal conditions: The flammable gas concentration is within a certain range, and an explosion occurs between the lowest concentration and the highest concentration.
  2. External conditions: ignition of arc flash or open flame, ambient temperature above the self-ignition point, and radiation of a certain energy, may detonate. Specific to the vehicle, it is reflected as: electric sparks; mechanical collision sparks; the temperature of the heat-prone parts such as motors, electronic controls, brakes, oil pumps and valves, etc., may cause explosions.

   2. The explosive gas environment can be divided into three areas according to the degree of danger
  Zone 0: Places where explosive gas environments occur continuously or exist for a long time. (Motorized industrial vehicles are not allowed to enter)
  Zone 1: Places where explosive gas atmospheres may occur during normal operation.
  Zone 2: During normal operation, an explosive gas environment is unlikely to occur, and if it occurs, it occurs occasionally and only exists for a short time.
   At present, the highest level of explosion-proof forklifts at home and abroad can only operate safely in Zone 1 and Zone 2.

  Three, the explosion-proof method adopted by the explosion-proof lithium ion forklift battery.

  1. Intrinsically safe: The energy of the circuit is limited, and the sparks, arcs and temperatures generated are not enough to ignite explosive gases in normal or short-circuit fault states.

  2, explosion-proof lithium ion forklift battery structure explosion-proof type: use isolation measures on the structure to isolate the electrical appliances from the surrounding environment. Commonly used are: flameproof type, increased safety type, positive pressure type, oil-filled type, sand-filled type, casting type and other forms.

At present, the explosion-proof lithium ion forklift battery of forklift trucks is mainly flameproof. It will not be damaged, and can ensure that when the internal flame gas spreads through the gap, the energy is reduced, which is not enough to detonate the gas outside the shell.
