Abstract
A kind of circuit that low tension battery can be charged during charging electric vehicle, including charger, charger connects battery management system main control module, connects battery by one-way conduction module II by one-way conduction module I, meanwhile, battery management system main control module connection battery.When can realize charging electric vehicle by this circuit, the low-tension supply exported using charger is charged to battery, it is ensured that battery is in full power state.
Description
Technical field
The utility model is related to a kind of charging circuit, more particularly to low tension battery can be filled during a kind of charging electric vehicle
The circuit of electricity.
Background technology
Low tension battery is the necessary power supply that electric automobile starts, and discharged or defective battery can cause the electric automobile can not to start.
In electric automobile electric discharge work, voltage changer can charge to low tension battery, it is ensured that battery is in full power state,
The utility model provides a kind of method charged to low tension battery during charging electric vehicle, can make battery often in full electricity
State, prevents battery from power shortage occur.
Utility model content
The technical problems to be solved in the utility model is to provide when a kind of circuit is simple, realization is charged to aid in electricity by low pressure
The circuit that source is charged to battery, to solve the problems, such as prior art.
The utility model uses following technical scheme：
The circuit that can be charged to low tension battery during a kind of charging electric vehicle, including charger 1, charger 1 is by single
Battery is connected to conducting module I connection battery management system main control module, by one-way conduction module II, meanwhile, cell tube
Reason main system control module connection battery.
The one-way conduction module I and one-way conduction module II are diode (led) module.
When the battery charges, the low pressure auxiliary power module set in charger 1 is by one-way conduction module I to electricity
The power supply of pond management system output 12V is used as charging wake-up signal；Connecting battery 2 by one-way conduction module II simultaneously is carried out
Charge.
The beneficial effects of the utility model：When can realize charging electric vehicle by this circuit, exported using charger
Low-tension supply charges to battery, it is ensured that battery is in full power state.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The circuit that low tension battery can be charged during a kind of charging electric vehicle that the utility model is provided, including charger
1, charger 1 connects battery management system main control module, connects electric power storage by one-way conduction module II by one-way conduction module I
Pond, meanwhile, battery management system main control module connection battery.
Above-mentioned one-way conduction module I is diode (led) module I 4, one-way conduction module II is diode (led) module II 3.
Low-tension supply needs to wake up battery management system work when being the charging electric vehicle of 12V, now, in charger
, used as charging wake-up signal, battery 2 is used as battery management system for the 12V low pressure accessory power supply of low-tension supply supplementary module output
The working power of active module.The accessory power supply of the output of charger 1 leads up to diode (led) module I 4 and is connected to battery management system
System main control module leads up to diode (led) module II 3 and is connected to low tension battery 1 and battery 1 is entered as charging wake-up signal
Row charges, and the acting as of two diode (led) modules avoids battery tension signal by battery using the principle of diode unilateal conduction
Management system is mistakenly considered charging wake-up signal.When can realize charging electric vehicle by this circuit, using the low of charger output
Voltage source charges to battery, it is ensured that battery is in full power state.
Low tension battery is the necessary power supply that electric automobile starts, and in electric automobile electric discharge work, voltage changer can
Low tension battery is charged, it is ensured that battery be in full power state, the utility model provide charging electric vehicle when pair
The circuit that low tension battery charges, can make battery be in full power state in Vehicular charging process, and such vehicle is in discharge and recharge
Full power state can be all kept in journey, is prevented battery from power shortage occur and is caused the vehicle cannot to start, it is also favourable to the life of storage battery.And
And circuit cost is cheap, line construction is simple.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
Protection domain of the present utility model.
