Battery — design description (Focus Turnier 1)

Six cells, connected in series, form the heart of a 12-volt car battery. Each cell is a combination of positive and negative plates, generating a voltage of about 2 volts through some kind of chemical action. The plates are made of grids of solid lead, which are filled with an active mass. The positive plate contains lead dioxide, the negative plate pure lead. Between them is a separator. It separates the plates from each other, but the electrolyte can pass through the microscopic pores. The electrolyte is a conductive liquid that is about 37% concentrated sulfuric acid and 63% distilled water.

The battery stores electrical energy

Chemical processes of energy absorption and accumulation take place inside the battery. When current is released, chemical energy is converted into electrical energy. The most important task of the battery is to supply the starter with the necessary power when starting the engine: depending on the engine and the type of starter, up to 2000 W of power is generated for a short time - for this, the battery must always be in the best shape. When starting a cold engine, most of the enormous power is lost due to internal losses due to friction. When starting a warm engine, the starter already requires about one fifth of the power. There is more "space" between all the oscillating and rotating units of the engine, and "hot" oils also become more fluid than cold lubricants, which slowly mix in the lubrication system.
