Abstract
A series connection and parallel connection conversion device for a storage battery pack comprises a contact circuit, a series connection power supply circuit and a parallel connection charging circuit. The contact circuit is equipped with contacts respectively connected with a positive electrode and a negative electrode of each battery in the storage battery pack, the series connection power supply circuit is equipped with connectors I which are one-to-one corresponding to the contacts of the contact circuit, the connectors I are connected through guide wires into a serials power supply mode on the base of positive and negative polarity of contacts in the contact circuit, the parallel connection charging circuit is equipped with connectors II which are one-to-one corresponding to the contacts of the contact circuit, and the connectors II are connected through guide wires into a parallel connection charging mode on the basis of positive and negative polarity of contacts in the contact circuit. When supplying power normally, the contact circuit is connected with the series connection power supply circuit, when needing to charge, the contact circuit is connected with the parallel connection charging circuit, and then, the storage battery pack is in parallel connection. A charger charges independently for each battery, which is low in charging voltage, reduces charging time, increasing work efficiency of the battery, and greatly prolongs the service life of the battery.
Description
Technical field
The utility model relates to a kind of equipment of batteries power supply, particularly a kind of batteries connection in series-parallel conversion equipment.
Background technology
Along with market development, electric motor car is popularized gradually, and environmental protection and people's life is brought many convenience, and the electric power storage group pond of the electric motor car in market all is that the series connection of polylith battery is used, the operating voltage height, and power is bigger.Its weak point is: its charging also is to adopt the series connection form, serial connection charge, and the voltage height, temperature rise is fast, and is big to cell damage, and battery power consumption descends simultaneously, reduction of service life.If there is a battery performance to descend in the battery pack, work discharge will be with this battery current discharge, during charging, is that the battery with ceiling voltage charges, the ceiling voltage battery is up to standard just to stop charging, and the battery of undertension still is not full of and just is forced to stop.And during battery discharge, be to discharge with the battery of afc voltage not, when under-voltage cell voltage is crossed when low, cause battery-powered deficiency, whole battery group just can not have been worked, though other battery also has electric energy, also has to quit work, thereby greatly reduce the power of other battery, acting, effect descend greatly.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of batteries connection in series-parallel conversion equipment of realizing series-fed, charged in parallel.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of batteries connection in series-parallel conversion equipment, be characterized in: comprise contact circuit, the power supply circuits that are connected in series, charging circuit is connected in parallel, contact circuit be provided with batteries in the contact that links to each other respectively of the both positive and negative polarity of every battery, the power supply circuits that are connected in series are provided with and the contact of contact circuit joint I one to one, and described joint I is connected to the series-fed pattern at the positive-negative polarity of contact in the contact circuit by lead; The charging circuit that is connected in parallel is provided with and the contact of contact circuit joint II one to one, and described joint II is connected to the charged in parallel pattern at the positive-negative polarity of contact in the contact circuit by lead.
The technical problems to be solved in the utility model can also come by the following technical programs to realize that further the contact in the described contact circuit is set to jack structure that corresponding joint I, joint II are set to cooperate with jack the contact pin of grafting.
The technical problems to be solved in the utility model can also come further to realize by the following technical programs, joint I in contact in the contact circuit and the corresponding power supply circuits that are connected in series interconnects by two shell fragments, the described charging circuit that is connected in parallel is provided with the insulation inserted sheet that can be inserted between above-mentioned two shell fragments, and the joint II of the charging circuit that is connected in parallel is arranged on the side of insulation inserted sheet.
The utility model compared with prior art, when normal power supply, contact circuit is connected with the power supply circuits that are connected in series, the battery of battery pack is connected, and provides high voltage source to motor.When needs charged, contact circuit was connected with the charging circuit that is connected in parallel, and at this moment battery pack is in parallel, charger charges separately to every battery, charging voltage is low, shortens the charging interval, if there is a battery phenomenon not up to standard to occur in the battery pack, charger continues to this piece battery charge, until being full of the charging that just stops up to standard, like this, not only improved the mechanical efficiency of battery, once charging increases the mileage number that drives, and can also prolong the useful life of battery greatly.This device is applicable to various equipment by polylith battery series-fed, especially needs the often electric motor car of charging.
