Why exactly do capacitors charge and discharge exponentially?
When a capacitor discharges through a simple resistor, the current is proportional to the voltage (Ohm''s law). That current means a decreasing charge in the capacitor, so a decreasing voltage. Which makes that the current is smaller. One could write this up as a differential equation, but that is calculus.
BMS (battery management system) peak current limit
I am trying to choose a BMS for a 18s6p lipo battery pack i am building. i am expecting a 180 A discharge current, but most of the options i found had a maximum discharge Current of about 100 A. my $begingroup$ I believe usually a battery management system will have some transistors which are used to control that battery discharge.
batteries
Discharge current from a battery is DETERMINED by load, not just "dependent". To control the discharge current you need to make a constant-current load, which is usually done with a powerful MOSFET, current-sensing resistor, and a feedback amplifier.. To "monitor" a discharge current, you need to insert a current monitor into discharge loop, usually a small
Battery Discharge Current Limit
On grid with battery and mppt inputs to the inverter it might be tricky to control discharge current while allowing full mppt throughput. If a "battery discharge current limit" was to exist, I would be able to easily utilise the battery in a much more efficient way, and the inverter would also run much more balanced.
How Does a Solar Charge Controller Work? | AltE Store
In most controllers, charge current passes through a semiconductor (a transistor) which acts like a valve to control the current. It is called a “semiconductor” because it passes current only in one direction. An example is a tiny maintenance module that prevents battery discharge in a parked vehicle but will not support significant
Current flow in batteries?
However, current more than likely won''t (depending upon the age/use of the battery). The reason why is because the voltage potential difference numerically from a good capacitor which has big area and small seperation which makes all the difference and thats why current is miniscule (but finite) in original problem.

How does a battery BMS work?
The basic components of a BMS for a battery pack typically include: Voltage and Current Sensors: These sensors measure the voltage and current of the battery cells and pack to ensure that they are operating within safe limits. Battery Control Unit (BCU): The BCU is the brain of the BMS and processes data from the voltage and current sensors.
Battery Charging and Discharging Parameters
However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery. In this case, the discharge rate is given by the battery capacity (in Ah) divided by the number of hours it takes to charge/discharge the battery.

why does higher current mean lower discharge capacity
Yes, twice the current discharge means half the time to battery depletion in the ideal case. The capacity (at least to a first order) is the same in both cases. EDIT: If the question is why would the battery capacity decrease over the expected ideal, then Brian''s comment is the answer. The internal battery impedance means more power
6 Frequently Asked Questions about “Why does the battery control the discharge current ”
What happens when a battery is discharged?
The chemical reaction during discharge makes electrons flow through the external load connected at the terminals which causes the current flow in the reverse direction of the flow of the electron. Some batteries are capable to get these electrons back to the same electron by applying reverse current, This process is called charging.
What is the difference between charging and discharging a battery?
Charging and Discharging Definition: Charging is the process of restoring a battery's energy by reversing the discharge reactions, while discharging is the release of stored energy through chemical reactions. Oxidation Reaction: Oxidation happens at the anode, where the material loses electrons.
How long can a battery be discharged?
Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged for pulses of up to 30 seconds. This limit is usually defined by the battery manufacturer in order to prevent excessive discharge rates that would damage the battery or reduce its capacity.
How a battery discharge process is performed in safe conditions?
For the discharge process to be performed in safe conditions, besides gathering information about the battery's capacity, SoC and SoH at the beginning of the process it is necessary to monitor the temperature and voltage of individual modules, preferably even groups of cells, as well as to control the discharge current.
Should a battery be fully discharged before charging?
For example, nickel cadmium batteries should be nearly completely discharged before charging, while lead acid batteries should never be fully discharged. Furthermore, the voltage and current during the charge cycle will be different for each type of battery.
What happens when a battery is charged by a DC source?
The external DC source injects electrons into the anode during charging. Here, reduction takes place at the anode instead of the cathode. This reaction allows the anode material to regain electrons, returning to its original state before the battery discharged.
