Battery grids function

The function of a battery grid is to act as a current collector, which is used to hold the active material and conduct electricity between the active material and the cell terminals. 

Lead alloys are used for casting grids, straps, terminal posts and connectors for lead—acid batteries. The plate grids have two major functions ... 

In Figure 13.6 the fraction of the locally used PV energy of the considered low-voltage grid is shown as a function of the installed battery capacity. In this application, this fraction can be increased from approximately 35% without battery storage up to 64%, whereas a value of 60% is already achieved with an installed capacity of... 

Compared to the Light Intelligent Module the only difference of this structure is that some functions of the BCU will be taken over by the MCU. This includes for example determination of SoC and SoH. This is the preferred solution for very large battery systems like energy storage systems for grid connection. 

Electrolyte inside the battery cells has two functions, which is to conduct electricity and heat. If the electrolyte is below the plate level, the area that is not covered by the electrolyte is not electrochemically active. The inactive area causes a concentration of heat in other parts of the cell and promotes grid corrosion. Periodically adding water to maintain the electrolyte level can provide an indication of charging efficiency. If the water consumption... 

Cathode (Positive Plate). The cathode consists of a depolarizer and a current collector. These depolarizers are powders and are nonconductive. In order for the depolarizer to function, a form of carbon is added to impart conductivity a binder is added for cohesion, and a metal grid is used as a current collector, a base for the cathode, to facilitate intercel connections and battery terminations. Possible cathode formulations are shown in Table 17.3...
