Problems solved by technology

[0005] 1. Different types of batteries: The current battery management methods are mostly for a certain type of battery. If two different types of batteries are used in combination, first, the performance of all types of batteries will not be fully utilized. , the second is that it may cause the performance of one type of battery to decline, shorten the service life of the battery, and even cause safety hazards
[0006] 2. New and old batteries: due to the decline in the performance of the old batteries, the charging and discharging characteristics will also change. If the same battery parameters are still used for management, the deterioration of the new batteries will be accelerated

Embodiment 1

[0144] This embodiment provides a storage battery device 1, such as figure 1 As shown, the storage battery device 1 includes a plurality of storage batteries 11 connected in parallel. Although only two are shown in the figure, there may be more than two.

[0145]A battery switch unit 13 connected in series with the battery 11 is provided on the parallel branch where each battery 11 is located. The battery switch unit 13 includes a current detection unit 131 and a charge and discharge control unit 133 connected in series. The charging / discharging current detected by the current detection unit 131 can be used for overcharging, overdischarging protection and preventing mutual charging between batteries.

[0146] The charge and discharge control unit 133 includes: a charge control unit 1331, used to turn on or off the charging circuit of the storage battery 11; a discharge control unit 1333, connected in parallel with the charge control unit 1331, to turn on or off Open the disch...

Embodiment 2

[0151] The present embodiment provides a charging and discharging monitoring method and a charging and discharging monitoring device of a storage battery device. The accumulator device therein comprises a plurality of accumulators connected in parallel. It should be noted that this embodiment mainly describes the charging and discharging strategy and implementation method between multiple storage batteries. The charging and discharging of a single storage battery is a mature technology and will not be described in detail.

[0152] like image 3 As shown, the charging and discharging management method of this embodiment includes:

[0153] Step 110, according to the set charging strategy, independently control the charge state and discharge state of each battery in the plurality of batteries, so as to realize the charging of the battery device;

[0154] Step 120, according to the set discharge strategy, independently control the charge state and discharge state of each battery...

Embodiment 3

[0259] This embodiment provides a battery charging and discharging monitoring system, such as figure 1 As shown, it includes the storage battery device 1 described in the first embodiment and the charging and discharging monitoring device 2 described in the second embodiment.

[0260] In the above embodiments, when different types or mixed use of new and old batteries are used, independent charge control and independent discharge control are performed on each battery by switching. The charging and discharging states of each battery can be freely combined according to the needs of the scene. Flexible charge and discharge management. At the same time, each storage battery can also include an independent current detection circuit, and the storage battery is protected according to the current detection result.

[0261] Combining the battery charging strategy and discharging strategy, the charging and discharging strategy at least includes:

[0262] Charge and discharge at the sa...

Abstract

The invention relates to a storage battery device, and a charging-discharging monitoring method, device and system thereof. The storage battery device comprises a plurality of storage batteries connected in parallel. Parallel branches where the storage batteries are located are provided with storage battery switching units in serial connection with the storage batteries respectively. The storage battery switching unit comprises a charging control unit configured to switch on or switch off a charging circuit of the storage battery, and a discharging control unit connected to the charging control unit in parallel and configured to switch on or switch off a discharging circuit of the storage battery. During monitoring, a charging state and a discharging state of each storage battery are controlled independently according to a set charging policy, and thus, the storage battery device is charged; and the charging state and the discharging state of each storage battery are controlled independently according to a set discharging policy, and thus, the storage battery device is discharged. According to the invention, a hybrid charging-discharging management of a plurality of types of storage batteries is realized, and advantages of different storage batteries are taken fully.

Description

technical field [0001] The present invention relates to a storage battery, and more specifically, to a storage battery device, a charging and discharging monitoring method, device and corresponding system thereof. Background technique [0002] With the development of energy storage technology, there are more and more types of batteries, such as lithium batteries, lead-acid batteries, high-temperature batteries, fast-charge batteries, etc. These different types of batteries have different characteristics and can be selected according to the usage scenarios. [0003] When upgrading or expanding the existing communication base station, many batteries of the original power supply system can continue to be used. Considering the investment cost, users will use two or more types of batteries at the same time, or use new and old batteries at the same time. [0004] The ensuing question is: [0005] 1. Different types of batteries: The current battery management methods are mostly f...
