Application of Battery
Considering the different types of lithium batteries, it can be complicated to know which one to use for an electric motor. There is a misconception that battery selection and sizing can be generalized. It is critical to understand the use case application and its requirements.
This white paper will compare two batteries with different characteristics and examine their properties and impacts in the decision-making process.
Electric Vehicle System Design Brief
At the time of release of this paper there is a good chance that, if you have purchased a vehicle recently, you have purchased some class of an electric vehicle (EV) which is either battery powered or a hybrid (containing both gasoline and batteries).
According to BCG analysts - with regards to car sales - global sales of all classes of EVs was about one-in-ten. Also as BCG points out, due in part to a mixture of government incentives, ever-tightening emissions regulations and the global volumized cost of electrification technology decreasing, “battery-powered electric vehicles (BEVs) and plug-in hybrids (PHEVs) will seize almost a quarter of the market by 2030.” (Boston Consulting Group, 2020).
Electric Vehicles are the Future and Here are the Basics
An electric vehicle (EV) is any vehicle that is powered by a battery, uses at least one electric traction motor for propulsion, and is charged by an external energy source.
These vehicles are part of our everyday life and are not just limited to standard automobiles. Some examples include trains, forklifts, scooters, bikes, vans, buses, golf carts, garbage trucks, trailer trucks, boats, planes, drones, lawn mowers, cranes, tractors.
Lithium-Ion Batteries 101
Rechargeable batteries are now extending far beyond providing the power for small, portable devices and are extending their adoption to larger mobile and stationary use. While the motor may be the source that actually propels an electric vehicle, the battery pack is its virtual heart and soul. A battery is an electromechanical device that stores and delivers energy. Energy is chemically stored in the battery and when the terminals of the battery are connected through a resistive load, electrical energy passes through the circuit.
Batteries are often separated into two categories, primary batteries and secondary or storage batteries. Primary batteries are designed to only be used once, by drawing a current until the voltage becomes too low and then discarding the cell. Secondary batteries are constructed in a way to allow the cell to be recharged after partial or complete discharge.
