Chassis energy storage battery is the battery with the largest market share and the widest range of use in chemical batteries, especially in the application fields such as starting and large energy storage. It is difficult to be replaced by other new batteries for a long time.
Why chassis energy storage battery system is popular?
How about the internal resistance of chassis energy storage battery system?
What are the effects of temperature on chassis energy storage battery system?
The price of chassis energy storage battery is low with comparative advantages of mature technology, excellent temperature performance, stability and reliability, high safety, good resource reuse and obvious market competitive advantage.
Compared with other battery metal materials, lead resources are relatively abundant. Lead reserves and recycled lead ensure the sustainable development of chassis energy storage battery industry for a relatively long time. chassis energy storage batteries are widely used and do not cause a shortage of lead resources for a long time.
The smaller the internal resistance of chassis energy storage battery system is, the stronger the discharge capacity of large current is, and the more sufficient the electric energy is released.
Any chassis energy storage battery system has a certain internal resistance more or less. In order to improve the load capacity, we hope that the internal resistance of the power supply is smaller.
The resistance R is the internal resistance of the chassis energy storage battery system. RL is the load, which is in series with the internal resistance R of the battery. The current flowing through R is equal to the load current. The greater the load current, the greater the current flowing through the internal resistance R, and the higher the voltage at both ends of R, so as to reduce the voltage applied at both ends of the load RL. If the voltage drop on the internal resistance is too large, RL will even be unable to obtain the rated working voltage and cannot work normally. Therefore, the smaller the internal resistance of the chassis energy storage battery system. When driving a heavy load, there will be no significant pressure drop on the internal resistance.
The internal resistance of the chassis energy storage battery system will increase with the service time, especially for the battery that is about to be scrapped.
The positive plate is PbO2 and the negative plate of chassis energy storage battery system is Pb. The conductivity and physical properties of these two substances change very little with temperature. Therefore, the temperature effect of the discharge performance of chassis energy storage battery system is caused by sulfuric acid. Because only its activation performance is related to temperature.
When the temperature of sulfuric acid electrolyte is high, the capacity output is more. When the temperature is low, the capacity output is less. The solubility of lead sulfate in sulfuric acid electrolyte will also decrease when the temperature decreases, which will inevitably saturate the lead ions around the electrode plate and force the formed lead sulfate crystal to be dense. It hinders the full contact between active substances and sulfuric acid electrolyte. Thus, the output capacity of chassis energy storage battery system is reduced.
When the battery is discharged, if the sulfuric acid electrolyte temperature is high, it will reduce the supersaturation of PbSO4 on the surface of the electrode plate in the sulfuric acid electrolyte. It is conducive to the formation of loose lead sulfate crystals, producing a thick and solid PbO2 layer during charging so as to prolong the service life of the active substances of the electrode plate. If the temperature of electrolyte is too high during charging, the diffusion of electrolyte will be accelerated and the corrosion of electrode grid will be intensified, which will shorten the service life of chassis energy storage battery system.
