For batteries, the energy density is measured in watt-hours per liter. Energy density is the amount of energy per unit of volume. Specific energy describes the energy carried in a unit of mass. For batteries, watt-hours per kilogram are commonly used. The SI unit for specific energy is the joule per kilogram. The specific energy of a battery is measured in the units of energy per units of mass. Other common types of rechargeable batteries are nickel-cadmium (NiCd), nickel-metal hydride (NiMH), lithium-ion (Li-ion), and lithium polymer (LiPo) batteries. The most common and oldest type of rechargeable battery is the lead-acid battery. Secondary batteries are rechargeable batteries that can be reliably recharged many (up to 1000) times. The run time of the bank t bank is determined asĬharging Li-ion batteries in an intelligent charger Secondary The discharge current of the bank, I bank is calculated as The charge in coulombs in the bank, Q bank is determined the sum of charges of all batteries in the bank: Where E bank, Wh is the rated energy in Wh stored in the bank. The energy in joules is calculated as follows:

N p is the number of batteries connected in series in a parallel set. N s is the number of batteries in a series set, and

The rated energy in watt-hours stored in the bank E bank is determined asĮ bat is the rated energy stored in one battery, The capacity in ampere-hours of the battery bank, C bank is determined as N s is the number of batteries in one or several series sets. V bank is the rated voltage of the battery bank, and V bat is the rated voltage of the battery in volts, The rated voltage in volts of the battery bank is determined as Q bat is the charge in a battery in coulombs (C) andĬ bat is the rated capacity of the battery in amperes-hours. t from the known capacity in Ah, which is the current a battery can provide for 3600 seconds:.Therefore, the charge in the battery is defined from Q = I We know that one ampere flowing in a wire for one second will use 1 coulomb of charge. The energy in joules, which are watts-seconds, is calculated as follows: V bat is the rated voltage of the battery in volts, andĬ bat is the rated capacity of the battery in Ah. The rated energy in watt-hours stored in a battery is calculated using the following formula:Į bat is the rated energy stored in the battery in watt-hours, It should also be noted that the allowed depth of discharge (DOD) of the battery further limits its operating time. Because of various external factors, the real run time will be about 30% less than calculated using this formula. The run time t and C-rate are inversely proportional: I bat is the current in amperes drawn from the battery,Ĭ bat is the rated capacity of the battery in amperes-hours (means amperes times hours), which is usually marked on the battery, andĬ rate is the battery C-rate, which is defined as the discharge current divided by the theoretical current draw at which the battery would deliver its rated capacity in one hour. The following formula shows the relationship between the current drawn from the battery, its capacity, and C-rate: At the end of this article, we will discuss the parallel and series connections of batteries into banks in more detail. An example of a battery bank is two 12 V 8 Ah rechargeable batteries connected in parallel used in a UPS, which do not have a common case. Examples: automotive 12 V 45 Ah battery consisting of six 2 V 45 Ah rechargeable cells.Ī battery bank or battery pack consists of several batteries (or battery modules) connected in parallel or in series, or both, series and parallel, which provide standby or emergency power and do not have a common case. Examples: AAA, AA, C, D cells (batteries).Ī battery is a device consisting of one (single-cell battery) or several (multi-cell battery) electrochemical cells installed in a single case and connected together in series and in parallel designed to power various electrical devices.

A cell usually has a nominal voltage of 1 to 3 volts depending on its chemistry.

It is a type of battery used for providing electrical power to portable devices such as flashlights. TerminologyĪ dry cell or a single cell or a single cell battery is the smallest form of an electric device capable of generating electrical energy from chemical reactions comprising of two electrodes, chemical mixture, and a case.

This is necessary because of inconsistent terminology in the field of electric batteries.
