The embodiment of the invention is derived from the fact that the service life of a lead-acid battery is influenced by different pumping currents, so that a super capacitor group is additionally arranged and connected with the lead-acid battery in parallel, electric power is provided for starting an engine (such as a starting motor 31) in a shared mode, the pumping current of the lead-acid battery is reduced to prolong the service life of the lead-acid battery, for example, the initial electrical output ratio of a brand new lead-acid battery is set to be about 50%, the initial electrical output ratio of the super capacitor group is set to be about 50%, so that half of the pumping current of the lead-acid battery can be reduced, the service life can be improved by more than 2 times compared with the use times of the same lead-acid battery, and the lead-acid battery belongs to a first benefit; the lead-acid battery is deteriorated along with the increase of the use times, half of the pumping current of the lead-acid battery is reduced, the deterioration of the lead-acid battery is slowed by one half, the service life of the lead-acid battery can be prolonged by more than 2 times, and the lead-acid battery belongs to the second benefit; the lead-acid battery can be degraded along with the increase of the use times, so that the first total internal resistance value of the lead-acid battery is gradually increased, and the second total internal resistance value of the super capacitor set is almost unchanged, so that the electric output ratio of the lead-acid battery is reduced until zero, the degradation degree of the electrolyte of the lead-acid battery can be greatly reduced, the degradation of the lead-acid battery is reduced by one half, the service life of the lead-acid battery can be prolonged by more than 2 times, and the lead-acid battery belongs to a third benefit; furthermore, the electric quantity required by a super capacitor bank which can independently start the starting motor 31 is only required to be fully charged when the service life capacity of the starting battery 33 is left 1% (determined by the battery capacity), the starting motor 31 can be started as long as the super capacitor bank can be fully charged, and when the lead-acid battery is aged to 50% electric quantity compared with the original design of a general lead-acid battery, the lead-acid battery cannot draw a target current (such as cold starting current CCA), so that the starting battery can be used to a true minimum remaining electric energy lower limit state which is enough to charge the super capacitor bank to a starting voltage, therefore, the function of using all available electric energy of the lead-acid battery can be realized, the purpose of prolonging the service life of the lead-acid battery can be achieved, and thus the use frequency of the lead-acid battery can be expected to be increased by 2 times, and the fourth benefit can be achieved; therefore, the average service life of the lead-acid battery is two years originally, the four synergistic benefits are combined, the service life of the lead-acid battery can be prolonged by more than 16 times (the service life is more than 32 years), however, the service life of a common vehicle is about 20 years, and therefore the lead-acid battery does not need to be replaced before the vehicle is scrapped.
And for example, the initial electrical output ratio R of the starting battery 33 is set at the time of installationr10Is 80%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 20%, the starting battery 33 is improved by more than 3 times in life by combining the above four kinds of synergistic effects (100%/80%) × (100%/80%) × 2, or the initial electrical output ratio R of the starting battery 33 is setr10Is 70%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 30%, the starting battery 33 is improved by more than 5 times in life by combining the above four kinds of synergistic effects (100%/70%) × (100%/70%) × 2, or the initial electrical output ratio R of the starting battery 33 is setr10Is 60%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 40%, the starting battery 33 is improved by 9 times or more in life by combining the above four kinds of synergistic effects (100%/60%) × (100%/60%) × (100%/60%) × 2, or the initial electrical output ratio R of the starting battery 33 is setr10Is 40%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 60%, the above four kinds of synergistic effects (100%/40%) × (100%/40%) × (100%/40%) × 2 are combined, the starting battery has a lifetime improved by more than 31 times, or the initial electrical output ratio Rr10 of the starting battery 33 is set to 30%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 70%, all areThe above-mentioned four multiplicative effects (100%/30%) x 2, the starting battery 33 has a life improved by more than 74 times, or the initial electrical output ratio Rr10 of the starting battery 33 is set to 20%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 80%, and combining the above four synergistic benefits (100%/20%) × (100%/20%) × (100%/20%) × 2, the starting battery 33 has an improved life by more than 250 times; thus, the initial electrical output ratio of the starting battery 33 is between 20% and 80%, or the initial electrical output ratio of the starting battery 33 is between 30% and 70%, or the initial electrical output ratio of the starting battery 33 is between 40% and 60%, or the initial electrical output ratio of the fast energy storage module 13 is between 20% and 80%, or the initial electrical output ratio of the fast energy storage module 13 is between 30% and 70%, or the initial electrical output ratio of the fast energy storage module 13 is between 40% and 60%, and the sum of the initial electrical output ratio of the starting battery 33 and the initial electrical output ratio of the fast energy storage module 13 is equal to 1, so that the degradation degree of the starting battery 33 can be greatly reduced, and the purpose of prolonging the service life of the starting battery 33 is achieved.
For another example, when the car has an idling stop system, since the number of times of starting is N times that of a general car, some car manufacturers add a start/stop (start/stop) system to their new generation car models in order to reduce pollution and fuel consumption, and turn off the engine when the car stops, when the foot of the driver moves from the brake pedal to the accelerator pedal, the engine is automatically restarted, which helps to reduce oil consumption in the urban driving and stop-and-go type busy period and reduce air pollution, when the starting battery 33 (such as a lead-acid battery) and the rapid energy storage module 13 (such as a super capacitor bank) are additionally provided with an idling stop system (starting/stopping system) for supplying power to the automobile, compared with the starting times of a common starting motor, the starting times are N times, N is a positive integer of arithmetic mean or carry, wherein the initial electrical output ratio R of the starting battery 33 is set.r10Is 40%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 60%, combinedThe above-described four synergistic effects ((100%/40%) × (100%/40%) × (100%/40%) × 2) are divided by N, the starting battery 33 is improved by 31 times divided by more than N life, or the initial electrical output ratio R of the starting battery 33 is setr1030%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 70%, the starting battery 33 is improved by 74 times divided by N or more in terms of the above four kinds of synergistic effects ((100%/30%) × (100%/30%) × 2) divided by N, or the initial electric output ratio R of the starting battery 33 is setr1020%, the initial electrical output ratio R of the fast energy storage module 13 is setr20Is 80%, and combining the above four synergistic benefits ((100%/20%) × (100%/20%) × (100%/20%) × 2) divided by N, the starting cell 33 is improved by a factor of 250 divided by more than N lifetime; thus, the initial electrical output ratio of the starting battery 33 is between 20% and 40%, or the initial electrical output ratio of the starting battery 33 is between 30% and 40%, or the initial electrical output ratio of the fast energy storage module 13 is between 60% and 80%, or the initial electrical output ratio of the fast energy storage module 13 is between 60% and 70%, wherein the sum of the initial electrical output ratio of the starting battery 33 and the initial electrical output ratio of the fast energy storage module 13 is equal to 1, so that the degradation degree of the starting battery 33 (e.g., a lead-acid battery) can be greatly reduced, and the purpose of prolonging the service life of the starting battery 33 can be achieved.
When the voltage value of the starting battery 33 is too low, which is also called under-voltage, indicating that the starting motor 31 cannot start normally, the fast energy storage module 13 is charged in advance by the power of the starting battery 33 in the charging mode, and the fast energy storage module 13 (such as a super capacitor bank) has a faster charging and discharging capability than the starting battery 33, so that the fast energy storage module 13 can be charged and accumulated to a required voltage value quickly; furthermore, the fast energy storage module 13 has the amount of power required to start the starter motor 31 alone, and even when the life capacity of the starter battery 33 is left 1% or less (depending on the capacity of the starter battery 33), the fast energy storage module 13 can be fully charged and the starter motor 31 can be started, so that the initial electrical output ratio of the starter battery 33 can be adjusted and controlled by using the parallel output ratio configuration system of the starter battery and the fast energy storage module disclosed by the invention, and the actual service life of the starter battery 33 is greatly prolonged.
Referring to fig. 1, 2 and 3, the first total internal resistance R of the starting battery 33 at the beginning is not changedTHInitially, the second total internal resistance R of the fast energy storage module 13CFirst resistance value R of first resistor component in initial period1And a second resistance value R of the second resistor assembly at the initial time2Selecting a larger capacity of the starting battery 33, or selecting a larger capacity of the fast energy storage module 13, for example, the starting battery 33 has a capacity of 55Ahr (CCA:370A, cold starting current), selecting a larger capacity of the starting battery 33 having 75Ahr (CCA:460A, cold starting current), if the starting motor 31 is similarly loaded with 360A, the fast energy storage module 13 (e.g., super capacitor bank) is added, the current load of the starting battery 33 is reduced by half to 180A (the electrical output ratio of the starting battery is 50%), for the starting battery 33 with a capacity of 75Ahr, the equivalent output ratio of 50% × (370A/460A) is 40%, so that the life of the starting battery 33 can be increased by 31 times from 3 times, although the replacement of the starting battery 33 affects the first total internal resistance of the starting battery 33, but the overall design achieves the design goal in the above-mentioned operation approach manner, this can greatly reduce the deterioration of the starting battery 33 (e.g., lead-acid battery), thereby prolonging the service life of the starting battery 33.
Referring to fig. 1 and fig. 3, the starting battery 33 with a smaller capacity is selected, or a first resistance value of a first resistor element initially electrically connected to the starting battery 33 is simultaneously increased or a second resistance value of a second resistor element initially electrically connected to the fast energy storage module 13 is simultaneously decreased, for example, the capacity of the starting battery 33 is originally 75ah (CCA:460A, cold start current), the starting battery 33 with a smaller capacity is selected to have 55ah (CCA:370A, cold start current), when the capacity is changed from 75ah to 55ah, if the starting motor 31 pumps 460A, the fast energy storage module 13 (e.g., super capacitor set) is additionally installed, the current of the starting battery 33 is halved to 230A (the electric output ratio of the starting battery 33 is 50%), for the starting battery 33 with a capacity of 55ah, if the first total internal resistance value of the starting battery 33 with a capacity of 55ah is the same as the first total internal resistance value of the starting battery 33 with a capacity of 75ah, the equivalent output of 50% × (460A/370A) — 62% electrical output ratio, at this time, by increasing the first resistance value of the first resistor element initially electrically connected to the starting battery 33 or decreasing the second resistance value of the second resistor element of the fast energy storage module 13 initially, the actual electrical output ratio of the starting battery 33 with a smaller capacity of 55Ahr from 230A to 180A is decreased to 50%, so that the life of the starting battery 33 can be maintained for more than 16 times to 32 years; if the first total internal resistance of the starting battery 33 with the 55Ahr capacity is different from the first total internal resistance of the starting battery 33 with the 75Ahr capacity, the first resistance of the first resistor component electrically connected to the starting battery 33 at the initial time and the second resistance of the second resistor component electrically connected to the fast energy storage module 13 at the initial time can be adjusted and corrected; also, if the first total internal resistance of the 55 Ahr-capacity starting battery 33 is higher than the first total internal resistance of the 75 Ahr-capacity starting battery 33, the starting battery 33 with a smaller capacity can be selected, the electrical output ratio of the starting battery 33 is adjusted to 50%, for example, the electrical output ratio of the starting battery 33 is 50% in the 3,000CC standard of the automobile, and when the starting battery 33 with a smaller capacity is replaced, because the first total internal resistance of the starting battery 33 with a smaller capacity is generally higher, the electrical output ratio of the starting battery 33 with a smaller capacity can be naturally adjusted and selected to be reduced to approximately 50%, so that the service life of the starting battery 33 can still be maintained for more than 16 times to 32 years.
