Q.1 Which of the following charging methods will you avoid as these are susceptible to damage from overcharging?
Answers
Answer:
Charging Schemes
The charger has three key functions
Getting the charge into the battery (Charging)
Optimising the charging rate (Stabilising)
Knowing when to stop (Terminating)
The charging scheme is a combination of the charging and termination methods.
Charge Termination
Once a battery is fully charged, the charging current has to be dissipated somehow. The result is the generation of heat and gasses both of which are bad for batteries. The essence of good charging is to be able to detect when the reconstitution of the active chemicals is complete and to stop the charging process before any damage is done while at all times maintaining the cell temperature within its safe limits. Detecting this cut off point and terminating the charge is critical in preserving battery life. In the simplest of chargers this is when a predetermined upper voltage limit, often called the termination voltage has been reached. This is particularly important with fast chargers where the danger of overcharging is gre
