Inside a typical 48v lithium ion battery pack for golf cart

The characteristics of lithium ion batteries can be clearly understood when time is taken to look inside the cell. The packs come in different sizes and shapes even though they look the same inside. If anyone were to take a battery pack apart (not recommended), some things would be discovered.

The cells can be cylindrical that is identical to the AA cells. They may also be prismatic in shape. This means that they are rectangular or square-shaped. 

They need a computer as well, and this comprises:

• temperature sensors to keep tabs on the temperature of the batteries

• regulator circuit and voltage convertor to ensure that current and voltage remain within safe levels 

• a notebook connector that is shielded and it lets information and power get in and out of the pack

• a voltage tap to monitor the energy capacity of all the cells within the battery pack

• battery charge state monitor that comes with a computer to handle the charging process and making sure recharge is quick as possible

When battery packs get very got during charge, the computer is supposed to shut power flow and cool things down. In such an instance, when a gadget, say a laptop, is left in a hot car, and when one tries to use it, the computer may refuse to power up until it cools off. When cells are discharged completely, the battery pack shuts down, and this can ruin the cells. The computer also tracks and sends out information about the battery meter. This allows the user to know the charge left within the battery and when the right time to recharge is. This computer is quite sophisticated and one reason why lithium-ion batteries tend to lose power even when they are not in use. The computer draws power from them. 

The cells

Just like other types of batteries, there is a metal outer case. This metal is important because the battery is pressurized. The cases have a vent hole that is pressure-sensitive. When the battery gets hot, and there are risks of explosions following overpressure, the vent releases the extra pressure. However, this may render the battery useless and should be avoided. The vent is used only for safety purposes. 

There is also the PTC or positive temperature coefficient switch. This keeps the battery safe from overheating. Choosing the ideal Chinese lithium battery manufacturer means all the different aspects of the battery are clearly defined and observed. This guarantees the safety and efficiency of the battery in question. 

The metal case is important in a 72v 100ah lifepo4 battery pack and other types of batteries. This is because it holds a spiral that comprises three sheets that are pressed together. It has:

• positive electrode

• negative electrode

• separator

Inside, the sheets are usually submerged in organic solvents to work as electrolytes. Ether is one of the most common solvents used. The separator is usually a micro-perforated plastic sheet that is quite thin. This is responsible for separating the negative and positive electrodes and allows ions to go through.
