Embodiment
As shown in Figure 3, constitute the series connection batteries by n cell batteries of connecting, the two ends of series connection batteries are connected with the charging output of serial connection charge device " S Charge ".Each cell batteries equalizing charger that all is connected in parallel.Constitute series connection thus, mixed equilibrium charging in parallel.
Serial connection charge device " S Charge " is used by three-phase mains (380V) power supply, by power supply " AC/DC " three-phase mains (380V) is converted to direct current, uses for each equalizing charger.Open series connection during charging simultaneously and fill device " S Charge " and whole equalizing charger in parallel.The equalizing charge electric current in parallel that has serial connection charge electric current and each cell batteries oneself during charging in each group series connection batteries.
The maximum charging voltage of serial connection charge device " S Charge " is defined (pressure limiting output) and is about 85% of series connection batteries maximum charging voltage, charging voltage along with batteries during charging rises, the charging current of serial connection charge device " S Charge " will descend, because each equalizing charger all charges to the cell batteries of correspondence simultaneously, the charging voltage of batteries continue to be risen, and the charging current of serial connection charge device " S Charge " reduces to 0 when the voltage of batteries surpasses the maximum charging voltage of serial connection charge device " S Charge ".
After the charging current of serial connection charge device " S Charge " reduces to 0, charging to each cell batteries of batteries continues to be undertaken by the equalizing charger in parallel with each cell batteries, because inconsistent (unbalanced) of storage battery quality, the time that the charging voltage of each cell batteries rises is all different, (equalizing charger is pressure limiting when the charging voltage of some storage batterys arrives the highest charging voltage, constant current output), charging current is reduced to minimum i.e. this cell batteries and is full of.When the charging voltage of series connection all cell batteries in the batteries arrives the highest charging voltage, charging current is reduced to when minimum, and promptly all cell batteries have been full of electricity (the series connection batteries is full of).
In serial connection charge device " S Charge ", dispose serial connection charge voltmeter " V " and ammeter " A ", can observe directly charging voltage and total charging current of series connection batteries during charging.In series connection batteries loop, dispose ammeter A1, can observe directly the charging current of series connection storage battery.On each equalizing charger, all disposed voltmeter " V " and ammeter " A ", but the charging voltage and the electric current of the corresponding cell batteries of Direct observation.
The utility model can charge to many groups of series connection batteries, as shown in Figure 3, constitute three series connection batteries " batteries 1 " by n cell batteries series connection respectively, " batteries 2 ", " batteries 3 ", three batteries are parallel with one another, and their parallel connected end is connected with the charging output of serial connection charge device " S Charge ".Each cell batteries equalizing charger that all is connected in parallel.Constitute series connection thus, mixed equilibrium charging in parallel.Equally, also in serial connection charge device " S Charge ", dispose serial connection charge voltmeter " V " and ammeter " A ", can observe directly charging voltage and total charging current of series connection batteries during charging.The series connection batteries " batteries 1 ", " batteries 2 ", " batteries 3 " every group all disposed ammeter " A1 ", " A2 ", " A3 ", can observe directly every group the series connection storage battery charging current.All disposed voltmeter " V " and ammeter " A " at each equalizing charger, but the charging voltage and the electric current of the corresponding cell batteries of Direct observation.In like manner, when also more groups of series connection batteries being charged, annexation such as above-mentioned embodiment are identical.
Use serial connection charge device " S Charge " to the early stage employing big electric current serial connection charge of series connection batteries in charging, adopt equalizing charger to carry out equalizing charge in the later stage of charging, thereby but solved series connection batteries large current charge and can reach the purpose of equalizing charge each cell batteries parallel connection.Dwindle the volume and weight of charging device, reduced cost.
