Embodiment 1

[0048] see figure 1 , a lithium thionyl chloride battery pack management system includes a lithium thionyl chloride battery pack, a current measurement unit 1 and an analysis unit 21 .

[0049] The battery pack in this embodiment is ER34615 batteries with 2 strings and 3 parallels with a total capacity of 57000mAH and a voltage of 7.2V.

[0050] The current measurement unit 1 includes a small resistance resistor R connected in series to the power supply outlet of the battery pack s , amplifying circuit 11 and ADC sampler 12, described ADC sampler 12 is connected with analysis unit 21;

[0051] The analysis unit 21 reads the sampled voltage value of the ADC sampler 12 according to the set cycle-to-cycle change.

[0052] According to the periodic operation of the instrument / instrument, the current is divided into two parts - standby and operation. The standby current is very small and relatively stable, while the operating current is large and varies greatly. The difference be...

Embodiment 2

[0075] see image 3 , a lithium thionyl chloride battery pack management system, which is different from the battery pack management system described in Embodiment 1: the lithium thionyl chloride battery pack management system in this embodiment also includes:

[0076] A temperature measurement unit 3, the temperature measurement unit 3 is connected to the analysis unit 22; the temperature measurement unit 3 is used to measure the ambient temperature of the lithium thionyl chloride battery pack.

[0077] The analysis unit 22 also calculates the self-discharge rate of the lithium thionyl chloride battery pack according to the temperature information measured by the temperature measurement unit 3; and obtains the remaining battery capacity according to the battery rated capacity, the self-discharge rate, and the battery capacity loss.

[0078] This embodiment also provides a management method for a lithium thionyl chloride battery pack, which is different from the management met...

Embodiment 3

[0107] A lithium thionyl chloride battery pack management system, which is different from the battery pack management system described in Embodiment 2 in that: the analysis unit in this embodiment obtains the current operating power consumption of the battery pack according to the remaining capacity of the battery, and according to The current operating power consumption results in a battery life time.

[0108] Further, the average power consumption is obtained according to the power consumption corresponding to the first m periods of the current period, and the average power consumption is used as the current operating power consumption of the battery pack, where m is a natural number. The m periods may be centered on the current period, m periods before or after the current period, or m periods including the current period.

[0109] This embodiment also provides a management method for a lithium thionyl chloride battery pack, which is different from the management method for...

Abstract

The invention relates to a lithium thionyl chloride battery pack management system which comprises a lithium thionyl chloride battery pack. The system further comprises a current measuring unit and an analyzing unit, wherein the current measuring unit measures current signals, and transmits the measuring result to the analyzing unit, and the analyzing unit collects the measuring result in a variable period mode, obtains the current value, and then obtains the battery capacity loss according to the current value. The invention further provides a lithium thionyl chloride battery pack management method. The lithium thionyl chloride battery pack management system and method have the advantages that battery electric quantity prediction is accurate and the battery working time is long.

Description

technical field [0001] The invention relates to a battery pack management system and method, in particular to a lithium thionyl chloride battery pack management system and method. Background technique [0002] Lithium thionyl chloride (Li / SOCL2) battery is the battery with the highest specific energy among all kinds of lithium batteries, and the actual specific energy can reach 660kwh / kg. In addition, lithium thionyl chloride batteries also have outstanding advantages such as stable discharge voltage and wide applicable temperature range. Due to these outstanding advantages of lithium thionyl chloride (Li / SOCL2) batteries, this type of battery is especially suitable for long-term on-line long-distance measuring instruments, telemetry instruments and other equipment. [0003] Remote measuring instruments generally need to rely on battery power for one year or more, but the battery power is limited. In order to meet the continuous and uninterrupted work of remote measuring in...
