Problems solved by technology

The discharge characteristics of general disposable lithium-manganese batteries are different from ordinary lithium batteries. During the discharge process, the battery voltage drops first, then rises and maintains, and then falls back after low voltage. That is to say, the battery voltage and battery power are not one-to-one correspondence, and The power is concentrated at one voltage point, so the first method of battery power calculation above is not applicable; while the coulomb counting method of the second method increases the power consumption of peripheral chips to more than 20uA, which is far beyond the demand of less than 5uA for the long-standby whole machine , so it cannot be applied

Abstract

The invention discloses a method for calculating the electric quantity of a lithium-manganese disposable battery in a super-long standby tracker and the tracker. The method comprises the steps of s1,GSM assigning an initial value to electric quantity of a first battery or a second battery if a single-chip microcomputer shows a power-on reset mark, and the acquired voltage of a battery is larger than a first preset voltage value; s2, calculating the power consumption percentage of the battery after the initial value of the electric quantity is assigned to the first battery; s3, assigning the remaining electric quantity of the battery; s4, calibrating the remaining electric quantity of the battery if the recollected voltage of the battery is smaller than the first preset voltage value, andotherwise, assigning the remaining electric quantity of the battery again; s5, determining whether the replacement battery criterion is met or not, and if so, returning to the s1, and if not, the stepcorresponding to assigning the remaining electric quantity of the battery; calibrating the remaining electric quantity of the battery after the initial value of the electric quantity of the second battery is assigned, and then determining whether a new battery is replaced or not. The tracker does not need to add a new device, so that the electric quantity calculation can be realized, and the calculation precision is high. The intelligent learning can be carried out according to historical data statistics stored in the GSM.

Description

technical field [0001] The invention relates to the technical field of vehicle trackers, in particular to a method for calculating the power of a lithium-manganese disposable battery in an ultra-long standby tracker and the tracker. Background technique [0002] The existing battery power calculation generally adopts the following two methods: [0003] 1. According to the corresponding relationship between battery voltage and power, the ADC (Analog-to-Digital Converter, analog-to-digital conversion pin) in the microcontroller collects the battery voltage data, and obtains the approximate data of the battery power according to the corresponding relationship table between the battery voltage and the battery power. This method is not very accurate in calculating the battery power. For example, the lithium battery power of a traditional feature phone is displayed in 4 grids, and the accuracy is 25%. [0004] 2. Coulomb counting method: This method is to estimate the remaining b...
