Description
Technical field
The invention belongs to the charging technique fields of low-speed electronic carriage, relate generally to a kind of low-speed electronic carriage 12V
Battery charging circuit.
Background technique
For electric four-wheel vehicle using battery as drive energy, environmental pollution is small, convenient fashion, market maintenance sustainable growth,
But the problem of electric four-wheel vehicle 12V battery easy power shortage, is not resolved always.After electric four-wheel vehicle increases central controlled lock function,
When the vehicle is parked, central controlled lock needs to receive the unlocking signal of remote-control key at any time, the central controlled lock under standby mode at any time
Power consumption always is needed, 12V battery is easy power shortage；Not only remote-control unlocking function can be lost but also key after 12V discharged or defective battery
Igniting starting can also fail, and cause great inconvenience to user；Based on the above reasons, with regard to needing to design in vehicle electric circuitry
Special charging circuit charges for 12V battery, and with this, to guarantee 12V battery, electricity is sufficient always.

DC converter works always, provides 12V power supply for vehicle, controls other loads not by relay after ignition switch closing
Work；But DC converter remains to as central controlled lock power supply.
Advantage: simple and convenient, at low cost for system the advantages of this scheme.
Disadvantage: because DC converter also needs other electrical equipments for vehicle to be powered, output voltage is no more than electric appliance
Part voltage rating is excessive, thus not can guarantee for the small battery of central controlled lock it is fully charged.Furthermore DC converter, which works always, to reduce
Its service life increases the failure rate of vehicle.
, increase by one piece of 12V battery
Increase by one piece of 12V battery as the power supply of central controlled lock function, vehicle total emergency stop switch also has power supply to maintain central controlled lock when closing
Work, after opening ignition switch, DC converter can charge for small battery.
Advantage: when vehicle emergency stop switch is closed, central controlled lock function is still valid, and the placement of vehicle short time will not lead to 12V
Discharged or defective battery.
Disadvantage: the central controlled lock under standby mode at any time needs power consumption always, so the 12V when vehicle is stored for a long time
Battery still can power shortage；Here it is most of vehicle parkings in the market, and once week, the original of a period of time is opened in needs starting in left and right
Cause.
Small-sized electric money carriage mainly takes both the above mode in the market at present, because above two scheme all has phase
The shortcomings that answering even the problems such as there are hidden dangers, so needing to design special 12V battery charging circuit to solve
