Description
Technical field
The present invention relates to monomer or intermodule series connection and the conversion equipment of conversion mutually in parallel in a kind of battery pack.
Background technology
To the pay attention to day by day of environmental protection and the progressively enhancing of people's environmental consciousness, bicycle is most of to be replaced by electric bicycle along with country, and new-energy automobile also has the trend that progressively replaces fuel-engined vehicle.No matter electric bicycle or electric automobile all be unable to do without a core component---power-supply system, and this power-supply system, only with a battery but is combined by a lot of battery series-parallel connections all not like mobile phone.Present everybody common concern lithium ion battery in power-supply system.But still there is certain problem in lithium ion battery when series connection is used.Take a classification ferric phosphate lithium cell of lithium ion battery as example, the cycle life of single ferric phosphate lithium cell can reach more than 2000 substantially, but when 12 conspired to create the group use, its performance was but had a greatly reduced quality, life-span only has 800-1000 time substantially, and what have is even lower.This is higher to the requirement of battery consistency when using in groups due to battery.Use in groups with single only the use some difference is like this arranged: 1. capacity volume variance between the interior monomer of battery pack: when using in groups, if certain battery capacity is less than normal, when charging, the constant current charge later stage, this cell voltage was the highest, when other battery does not reach the constant voltage value, it might overcharge, and single this problem that do not exist of only using; 2. self discharge difference: when the battery list only uses, if its self discharge is large, discharge after shelving a period of time, just this time discharge capacity is lower, and when again charging, the capacity before its capacity can add to again and shelve does not affect later discharge performance.But when using in groups, if some self-discharge of battery are excessive, when discharging after a period of time, it is discharged at first shelving, and this moment, other battery capacity did not discharge yet, can not be full of by the large battery of restriction self discharge of other battery charging capacity when charging, so As time goes on, the battery that self discharge is large can fill capacity compare fewer and fewerily with other battery, cause at last whole battery capacity defective; 3. difference polarizes between each monomer in battery pack: even when each battery in battery pack is initial, Performance Ratio is more approaching, but will inevitably be variant through each battery polarization state in battery pack after long-term the use, when the series connection constant current charge, no matter battery polarization is big or small, charging current by each battery all equates, will decay by the large battery life of Accelerated polarization like this.In order to address the above problem; except select when the battery combo as far as possible consistency preferably battery match to dwindle between batteries monomer initial difference as far as possible; the common practice that solves self discharge difference and capacity volume variance is to adopt the mode of equilibrium+charge protection; though there is the drawback that cost is high, reliability is still to be tested in effective head it off on this kind mode principle and can't solves the difficult problem of polarization difference between monomer when implementing.
Someone adopts another mode to solve above problem: adopt charged in parallel.When charged in parallel; the charging voltage of battery pack is with the composition monomer whose or module voltage is consistent; the charging of battery pack at this moment is the equal of just monomer or module charging; and charged in parallel has individual advantage; can carry out automatic shunt according to the polarization situation of its each branch road consistent to reach voltage; as large in certain monomer polarization, its electric current of getting is corresponding will be less, and it is protected.
Therefore, in a kind of battery pack of needs, monomer or intermodule are connected with the conversion equipment of mutually changing in parallel to address the above problem.
