What are the main characteristics of battery?
Answers
The use of batteries in photovoltaic systems differs from the use of batteries in other common battery applications. For photovoltaic systems, the key technical considerations are that the battery experience a long lifetime under nearly full discharge conditions. Common rechargeable battery applications do not experience both deep cycling and being left at low states of charge for extended periods of time. For example, in batteries for starting cars or other engines, the battery experiences a large, short current drain, but is at full charge for most of its life. Similarly, batteries in uninterruptible power supplies are kept at full charge for most of their life. For batteries in consumer electronics, the weight or size is often the most important consideration. This section provides an overview of the critical battery characteristics or specifications, including battery voltage, capacity, charging/discharging regimes, efficiency, etc
Answer:
Characteristics of the Battery
The use of batteries in photovoltaic systems is distinct from the use of batteries in other types of batteries. The important technological concerns for photovoltaic systems are that the battery has a long lifetime at virtually full discharge circumstances. Deep cycling and being kept at low levels of charge for long periods of time are not common in rechargeable battery applications. In batteries used to start vehicles or other engines, for example, the battery sees a substantial, brief current drain yet remains fully charged for most of its life. Similarly, uninterruptible power supply batteries are kept charged for the majority of their lives. The weight or size of batteries in consumer gadgets is sometimes the most critical concern. This section contains information.
When choosing a battery, the following factors must be taken into account:
Type.
- Voltage.
- Discharge curve.
- Capacity.
- Energy density.
- Specific energy density.
- Power density.
- Temperature dependence.
