Abstract
The utility model discloses a voltage acquisition circuit of a low-energy-consumption lithium ion battery, which comprises the following components: a battery, anode acquiring circuits, a total cathode acquiring circuit, acquiring parallelly connected branch circuits and a single-chip microcomputer. The anode acquiring circuits are provided with gating switches and resistors. The total cathode acquiring circuit is an acquiring common-ground point. The acquiring parallelly connected branch circuits are provided with parallelly connected branch resistors. The anode acquiring circuit starts from the anode of each string of battery. The gating switches and the resistors are connected with an input port of the single-chip microcomputer. The acquiring parallelly connected branch circuits are connected with the anode acquiring circuits and the total cathode acquiring circuit. When voltage acquisition is required, the single-chip microcomputer causes the gating switch to be switched on; the acquiring circuit is conducted; and the voltage data are transmitted to the single-chip microcomputer. When voltage acquisition is not required, the gating switch is switched off. On/off of the gating switch on each anode acquiring circuit is controlled through the single-chip microcomputer, thereby preventing energy consumption of the resistors on the anode acquiring circuits and the acquiring parallelly connected branch circuits when the voltage is not acquired.
Description
[technical field]
The utility model relates to new energy field, relates in particular to a kind of voltage collection circuit of low energy consumption lithium ion battery group.
[background technology]
Energy crisis, shortage of resources, environmental pollution are the three large severe challenges that human survival faces, and finding secondary resource clean, renewable, resource-conserving is the vital task that realizes that human social will solve.Raising along with expanding economy and industrial requirement, people are more and more strong to the battery requirements of high-energy-density, lithium ion battery has that operating voltage is high, energy density is large, have extended cycle life, the advantages such as self-discharge rate is little, environmental protection, become the trend of secondary cell, now be widely used in the portable electricity consuming productses such as wireless telecommunications, digital camera, and tentatively in special dimension widespread uses such as aviation, national defence.
Lithium ion battery is as emerging electric automobile energy bag, and its feature of environmental protection, flying power, dynamic property, the characteristics that have extended cycle life, be the ideal power battery of electric automobile.
The voltage acquisition of tradition lithium ion battery group is provided with resistance on Acquisition Circuit, and when not needing to gather voltage, resistance can continue power consumption, thereby affects the consistance of battery electric quantity, reduces energy output and the charged vacant time of whole energy bag.
In view of above drawback, be necessary to provide a kind of voltage collection circuit of low energy consumption lithium ion battery group to overcome above-mentioned defect in fact.
[utility model content]
The purpose of this utility model is to provide a kind of voltage collection circuit of low energy consumption lithium ion battery group, and it has solved the resistance energy consumption issues of conventional voltage Acquisition Circuit when not needing to gather voltage.
To achieve these goals, the utility model adopts following technical scheme: a kind of voltage collection circuit of low energy consumption lithium ion battery group, it comprises electric battery, anodal Acquisition Circuit, total negative pole Acquisition Circuit, gather parallel branch, single-chip microcomputer, on described anodal Acquisition Circuit, gating switch and resistance are installed, described total negative pole Acquisition Circuit is for gathering place altogether, described collection parallel branch is equipped with parallel branch resistance on connecting, described anodal Acquisition Circuit is starting point just very from every crosstalk pond, connect gating switch, resistance is to the single-chip microcomputer input port, described collection parallel branch connects anodal Acquisition Circuit and total negative pole Acquisition Circuit, when needs gather voltage, the adhesive of Single-chip Controlling gating switch, the Acquisition Circuit conducting, voltage data is transferred to single-chip microcomputer, while not needing to gather voltage, disconnect gating switch.
The beneficial effects of the utility model are, by the adhesive of gating switch on each anodal Acquisition Circuit of Single-chip Controlling, thus the anodal power consumption that gathers resistance on line circuit and parallel branch while avoiding not gathering voltage.
[accompanying drawing explanation]
The voltage collection circuit schematic diagram that Fig. 1 is a kind of low energy consumption lithium ion battery of the utility model group.
[embodiment]
The voltage collection circuit of a kind of low energy consumption lithium ion battery of the utility model group, it comprises the battery cell1 that will detect voltage, cell2, cell3, be installed on anodal Acquisition Circuit ZL1, ZL2, gating switch K1 on ZL3, K2, K3, be installed on the resistance R 1 on anodal Acquisition Circuit, R2, R3, be installed on and gather parallel branch BL1, BL2, resistance BR1 on BL3, BR2, BR3, described anodal Acquisition Circuit is with every crosstalk pond starting point just very, connect gating switch K and resistance R to Chip Microcomputer A/D input port P, described collection parallel branch BL is connected to total negative pole Acquisition Circuit FL between the resistance R of anodal Acquisition Circuit ZL and single-chip microcomputer input port P, described parallel branch resistance BR is installed on and gathers on parallel branch BL.
The principle of work of the utility model lithium battery group voltage collection circuit is such: when needs gather the voltage V1 of cell1, Chip Microcomputer A/D is closed gating switch K1 first, gather voltage Vk1, then, more closed gating switch K2, voltage Vk2 gathered, V1=Vk2-Vk1 now, Chip Microcomputer A/D calculates the voltage V1 of cell1, and when not needing to gather the voltage V1 of cell1, Chip Microcomputer A/D disconnects gating switch K1, K2; When needs gather last crosstalk pond of electric battery cell3, because total negative pole Acquisition Circuit does not increase gating switch for gathering place altogether, only need closed gating switch K3, just can directly collect voltage Vk3, when not needing to gather the voltage V3 of cell3, disconnect gating switch K3.
The voltage collection circuit of a kind of low energy consumption lithium ion battery of the utility model group, be not restricted to described in instructions and embodiment, therefore can easily realize additional advantage and modification for the personnel of familiar field, therefore, in the situation that do not deviate from the spirit and scope of the universal that claim and equivalency range limit, the utility model is not limited to specific details, representational equipment and illustrates here and the examples shown of describing.
