In order that those skilled in the art has more clearly awareness and understanding to power supply of the invention and charging principle,
The course of work under different power supplies and charge mode is described in detail below with reference to accompanying drawing 1 and accompanying drawing 2.
First, 12V direct current supplys:
12V direct current supplys are provided by 12V automobile storage batteries, there is provided voltage be VDC1, when power switch K1 throws H, VDC1
Jing power switch K1 are connected to load, the DC voltage VO=VDC1 in load.
2nd, 14.4V high-capacity lithium batteries are powered:
14.4V high-capacity lithium batteries are powered and are carried by the 14.4V high-capacity lithium batteries in 14.4V lithium batteries and management circuit
For, there is provided voltage be VDC2, the DC voltage VO=VDC2 when power switch K1 throws L, in load.Specifically, 14.4V lithiums
In battery and management circuit in addition to containing 14.4V high-capacity lithium batteries, also charging overvoltage protection circuit, charging overcurrent protection is electric
Road, charging balanced circuit, electric discharge under-voltage protecting circuit, overcurrent protection circuit for discharging electricity and discharge equalizing circuit, these circuits are referred to as
It is inseparable with 14.4V high-capacity lithium batteries for battery management circuit.
Wherein, with 12V direct current supplys it is preferential, VS1 between 12V direct current supplys and 14.4V high-capacity lithium batteries are powered
For the 12V direct current supply under-voltage protection voltages for arranging.As VDC1 > VS1, first comparator A1 output high level, the high level
Control power switch K1 throws H, VO=VDC1, and whole machine output is provided by 12V direct current supplys;When VDC1 is reduced to VDC1 < VS1,
First comparator A1 exports low level, and the low level makes power switch K1 throw L, VO=VDC2, and whole machine is exported by 14.4V Large Copacities
Lithium battery is provided.
3rd, AC charging:
The alternating current of VAC is input into constant current/pressure limiting AC charger by 220V Alternating Current Power Supplies end, constant current/pressure limiting exchange is filled
Electrical equipment charges to the high-capacity lithium battery in 14.4V lithium batteries and management circuit by constant current/voltage limiting mode, and constant current value is IC1, limit
Pressure value is VC1.Constant current/whether pressure limiting AC charger works to be controlled by VE1, charger operation when VE1 is high level, and VE1 is
Charger does not work during low level.
4th, DC charging:
The direct current of VDC1 is input into variable constant current/pressure limiting DC charger, variable constant current/limit by 12V DC power supply terminals
Pressure DC charger charges to high-capacity lithium battery, and charging current is IC2, and IC2 is controlled by VCC, IC2 and VCC passes in direct ratio
System, voltage limiting value is VC2.Variable constant current/whether pressure limiting DC charger works to be controlled by VE2, charger work when VE2 is high level
Make, charger quits work when VE2 is low level.
Wherein, with AC charging be between AC charging and DC charging it is preferential, VAC Jing voltage detecting circuits obtain with
The directly proportional DC voltage VM1 of VAC sizes, VS2 are the Alternating Current Power Supply under-voltage protection voltage for arranging.As VM1 > VS2, table
Bright Alternating Current Power Supply is normal, and the VE1 of the second comparator A2 outputs is high level, and VE1 control AC charger work, phase inverter N1 is defeated
The VE2 for going out is low level, and VE2 makes DC charger quit work.As VM1 < VS2, show that Alternating Current Power Supply is abnormal, second
The VE1 of comparator A2 outputs is low level, and VE1 makes AC charger quit work, and the VE2 of phase inverter N1 outputs is high level,
VE2 makes DC charger work.
The adaptive principle of DC charging power:
When direct current supply is to lithium cell charging, when direct current supply voltage drops to close to under-voltage protection value, lithium should be reduced
The charging current of battery, when direct current supply voltage is less than under-voltage protection value, should stop to lithium cell charging.Direct current supply is simultaneously
During to load supplying and to lithium cell charging, due to the power output of direct current supply it is limited, in load supplying power and lithium battery
Between charge power, preferential proof load output power is answered.The present invention passes through DC charging current self adaptation direct current supply voltage
To complete requirements above.VS3 is the self adaptation work threshold voltage for arranging:During VDC1 > VS3, adaptive circuit does not work;
During VDC1 < VS3, adaptive circuit is started working.VS4 be arrange Self Adaptive Control sensitivity voltage, VS4=0.5~
1.2V。
Can be obtained according to the composition frame chart of signal processing circuit in Fig. 2:First adder AD1 is output as:VS3-VDC1;Second
Adder AD2 is output as:VS4-(VS3-VDC1);Proportional amplifier P is output as:VCC2=P × (VS4- (VS3-VDC1)).Tool
In body design, it shall be guaranteed that in VDC1=VS3, P × VS4=VCC1;In design, should also ensure VS4=VS3-VS1.
As VDC1 > VS3, show that direct current supply output voltage is higher, and direct current supply power output can simultaneously meet right
Load supplying power and the requirement to lithium cell charging power, DC charger is filled by the maximum charging current for arranging to lithium battery
Electricity.Now, the 3rd comparator A3 outputs high level, the high level makes controlling switch K2 throw H, VCC=VCC1, VCC1 be direct current most
The setting voltage of big charging current, adaptive circuit does not work.
As VDC1 < VS3, show that direct current supply output voltage is relatively low, or direct current supply power output can not meet simultaneously
The needs of bearing power and charge power.The difference of VS3-VDC1 is bigger, represents that amplitudes of the VDC1 less than VS3 is bigger or represents negative
Carrying power causes the amplitude of VDC1 Voltage Drops bigger, should now reduce the charging current to lithium battery to reduce to lithium battery
Charge power.When the difference of VS3-VDC1 increases to VS3-VDC1=VS4, it can be seen from design condition VS4=VS3-VS1
VDC1=VS1, shows that now VDC1 has dropped to under-voltage protection value, and to the charging current of lithium battery 0 should be decreased to.
As VDC1 < VS3, the 3rd comparator A3 output low levels, the low level makes controlling switch K2 throw L, VCC=
VCC2, adaptive circuit is started working.From VCC2=P × (VS4- (VS3-VDC1)) and P × VS4=VCC1:Work as VDC1
When dropping to VDC1=VS3, VCC2=P × VS4=VCC1, i.e. VCC=VCC1, when showing that adaptive circuit is just started working,
DC charging current is the value that VCC1 is arranged.VDC1 continues to decline, and the difference of VS3-VDC1 becomes big, and VCC2 diminishes, and VCC diminishes,
DC charging current diminishes.When VDC1 drops to makes the difference of VS3-VDC1 increase to VS3-VDC1=VS4, VCC2=0,
VCC=0, DC charging current IC2=0.
The high-power integrated lithium battery that the present invention is provided, directly exports and 14.4V high-capacity lithiums electricity with direct current supply
The function of pond output, and direct current supply directly exports preferentially;With AC charging and DC charging function, and AC charging is excellent
First.In DC charging, with DC charging power adaptive function:Drop near under-voltage value in direct current supply output voltage
Or load supplying power is increased to when direct current supply output voltage is dropped near under-voltage value, DC charging current is supplied with direct current
The decline of electricity output voltage and quickly reduce;When direct current supply output voltage declines or drops into under-voltage value, DC charging electricity
Stream is reduced to 0.
