Abstract
The utility model discloses a non-circulation battery-powered system including a first battery pack and a second battery pack which are connected in parallel with each other. An output terminal of the first battery pack and an output terminal of the second battery pack are provided respectively with relays. The first battery pack and the second battery pack are both composed of a plurality of battery modules connected in series. The non-circulation battery-powered system is of simple structure and low production cost. The power supply system of the structure avoids the emergence of circulation, so that the service lives of the battery modules are prolonged. When the two parallel battery packs differs in total voltage, the system can give an alarm signal so as to be maintained as soon as possible.
Description
Technical field
The utility model relates to a kind of battery power supply system without circulation.
Background technology
At present, battery case is all undertaken forming after connection in series-parallel by the battery module of standard.And in order to keep the balance of voltage of battery module, generally first carry out parallel connection, and then series connection, battery module in parallel, if voltage has had difference, just causes " circulation " to flow between two battery modules.And such " circulation " can cause two battery modules in parallel to undermine, until two battery modules all break down.
Utility model content
The utility model object is that the defect existing for prior art provides a kind of battery power supply system without circulation.
The utility model for achieving the above object, adopt following technical scheme: a kind of battery power supply system without circulation, comprise the first battery pack parallel with one another and the second battery pack, the output of the output of described the first battery pack and the second battery pack is respectively arranged with relay; Described the first battery pack and the second battery pack are all comprised of the battery module of a plurality of series connection.
The beneficial effects of the utility model: the utility model is simple in structure, make cost low.The electric power system of this structure has been avoided the appearance of circulation, thereby makes the life of battery module.When the total voltage of two battery pack in parallel has difference, system can provide alarm signal, thereby safeguards as early as possible.
Accompanying drawing explanation
Fig. 1 structure principle chart of the present utility model.
Embodiment
Shown in Fig. 1, be a kind of battery power supply system without circulation, comprise the first battery pack 1 parallel with one another and the second battery pack 2, the output of the output of described the first battery pack 1 and the second battery pack 2 is respectively arranged with relay; And described the first battery pack 1 and the second battery pack 2 are all comprised of the battery module of a plurality of series connection.
System when operation, the relay R of first closing elay-1, when system detects total voltage in the first battery pack 1 and the total voltage in the second battery pack 2 and has larger difference, system can automatic alarm, and reminding user is safeguarded.Now, the first battery pack 1 still can allow system normally move.When if the voltage difference of the first battery pack 1 and the second battery pack 2 is little, the relay R of just closing elay-2, system can normally be moved.When system is out of service, can disconnect relay R elay-1 and relay R elay-2 simultaneously, now the circulation between each battery module is 0.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
Claims (1)
1. without a battery power supply system for circulation, it is characterized in that, comprise the first battery pack parallel with one another and the second battery pack, the output of the output of described the first battery pack and the second battery pack is respectively arranged with relay; Described the first battery pack and the second battery pack are all comprised of the battery module of a plurality of series connection.
