Fast and slow battery charging and discharging

by:Vglory      2020-08-29
Capacity of lead acid lithium battery lead - not a fixed quantity, but according to different is how quickly. The empirical relationship between the discharge rate and the capacity, is called a peck specific law. When the battery charge or discharge, the initial reaction of chemicals affect only, this is the interface between the electrode and the electrolyte. With the passage of time, the charge storage on the interface of chemical, often referred to as 'interface', to spread, the chemicals in the whole volume of the active material. If the battery is only a few minutes of fast charging, panels charge near the interface between the plate and the electrolyte. Battery voltage up to the nearest charging voltage and charging current is decreased obviously. After several hours, the charge will sweep volume of electrodes and the electrolyte interface, interface charge is very low, it may not be enough to start the car. On the other hand, if the battery is a slow charge, it takes a long time, and then will become more fully charged battery. In the interface of a slow charge charge has time to reassign number of electrodes and the electrolyte, the supplement of the charger. The battery voltage is lower than the charge voltage in the process flow to charge batteries. Similarly, if the battery is rapid discharge ( Such as the car, a current more than 100 amps) For a few minutes, can produce lower voltage and power. However, it may be just lost its interface charge. If a battery discharge is stopped for a few minutes can resume normal operation, in the proper voltage and power of discharge. On the other hand, if the battery is a slow, deep discharge ( If leave the car lights, a current is less than 7 amperes) Any observation, reduce the performance of the battery may be permanent.
