Heat, and reduce adhesion risk.
For ease of understanding the present embodiment, a kind of battery heating circuit disclosed in the embodiment of the present invention is prevented first
Adhesion detection protection circuit describes in detail.
Fig. 1 shows that battery heating circuit provided in an embodiment of the present invention prevents adhesion and detects protection circuit diagram.
The detection protection circuit as shown in Figure 1, a kind of battery heating circuit provided in this embodiment prevents adhesion, including being arranged on
In battery heating circuit and it is sequentially connected the heating relay 10 connect, current-limiting circuit 20, current divider 30 and also contacts device
40；Wherein, heating relay 10 is arranged at the anode of battery, and also contacts device 40 is arranged at the cathode of battery；
Here, the mode of heating of heating circuit is hyperbaric heating, and electricity is taken from charging pile when battery charges, from battery during electric discharge
System takes electricity, and the efficiency of heating surface is 10 DEG C/h.
When battery heating circuit have high current by when, current-limiting circuit 20 carries out current limliting, such as high current is consumed, from
And prevent battery heating circuit due to frequently cut-off or short circuit and generate dash current or surge current, with ensure it is big without moment
Rush of current heats 10 main contacts of relay, and then avoids heating 10 adhesion of relay；
Current divider 30 measures DC current and uses, and voltage is generated at resistance both ends when passing through resistance according to DC current
Principle is made.Current divider 30 is actual be exactly a resistance value very little resistance, when have DC current by when, generation pressure drop, for straight
Galvanic electricity flow table is shown.
In the present embodiment, current divider 30 is used to detect the electric current in heating circuit.Increase by one on battery heating circuit
Current divider 30, by examine the size of current in battery heating circuit judge heat relay 10 whether adhesion.Here, current divider
30 are also connected with battery management system BMS.
The disconnection of BMS control heating relays 10 and closure, if BMS orders after disconnecting heating relay 10, and
Predetermined current is still detected in preset time, here presetting at the time can be set according to demand, and heated current is generally 5A, here
Predetermined current can be 2A, then is judged as heating 10 adhesion of relay.In addition, BMS orders, heating relay 10 is certain after being closed
In time, current divider 30 can not detect electric current, then be judged as heating unit open circuit.So as to detect heating relay 10
Adhesion and the situation of heating unit open circuit, to adopt remedial measures in time.Play the role of circuit protection.
As a kind of enforceable mode, current-limiting circuit 20 includes arc extinguishing inductance coil and is connected anti-parallel to arc extinguishing inductance
The diode at coil both ends.Here, 200mH can be selected in arc extinguishing inductance coil.
Under normal circumstances, heated current can pass through arc extinguishing inductance coil, and the characteristic of inductance is logical direct current, and resistance is handed over
Stream prevents current step from changing；When have instantaneous large-current by when, according to the characteristic of inductance, arc extinguishing inductance coil can generate
One counter electromotive force, counter electromotive force cause diode current flow, so as to consume high current, play the role of current limliting, so as to ensure
There is no high current by heating relay 10, and then avoid heating 10 adhesion of relay.
Further, the fuse being arranged in battery heating circuit, one end connection heating relay of fuse are further included
The cathode of device 10, other end connection current-limiting circuit 20.
Fuse is act as：When circuit malfunctions or exception, constantly raised with electric current, and raised electricity
Stream is it is possible that damage the device in circuit, it is also possible to burn circuit and even cause fire.If setting fuse in circuit, that
, fuse will current anomaly be increased to certain height and it is certain when, itself fusing cut-out electric current, so as to play
The effect of protection circuit safety operation.
Further, further include the heating unit being arranged in battery heating circuit, heating unit respectively with current-limiting circuit
20 are connected with current divider 30.Wherein, heating unit includes heating film.The PI heating films of PTC materials may be employed in heating film.
PTC materials are equivalent to the resistance of a positive temperature coefficient, are more than resistance value after Curie temperature when its temperature heats film temperature
Meeting step forms a kind of state of approximate open circuit into infinity.
Fig. 2 shows that battery heating circuit provided in an embodiment of the present invention prevents adhesion and detects protection circuit diagram.
As shown in Fig. 2, the anode of the anode connection battery of heating relay 10, the cathode connection fusing of heating relay 10
One end of device, the other end connection arc extinguishing inductance coil of fuse and one end of diode, arc extinguishing inductance coil and two poles
The other end of pipe is connected with heating film, and heating film connects the cathode of current divider 30, the anode connection also contacts device of current divider 30
40 cathode, the cathode of the anode connection battery of also contacts device 40.
Specifically, FL2-400A direct currents current divider 30 may be employed in current divider 30.Also contacts device 40 may be employed
HFE18V-40/750-24-HL5.It should be noted that heating relay 10 here can select rated current as 40A, and
And the insurance with 30A.In addition, rated current is less than the specified electricity equal to heating relay 10 on the Type Selection Principle of fuse
Stream.
The present embodiment additionally provide a kind of battery heating circuit prevent adhesion detection protection system, heated back including above-mentioned battery
Road, which prevents adhesion, detects protection circuit, further includes battery management system BMS.
The disconnection of BMS control heating relays 10 and closure, if BMS orders after disconnecting heating relay 10, and
Predetermined current is still detected in preset time, here presetting at the time can be set according to demand, and heated current is generally 5A, here
Predetermined current can be 2A, then is judged as heating 10 adhesion of relay.At this point, BMS reports catastrophe failure grade to full-vehicle control
Device VCU will disconnect charge relay in charging process, and main relay is disconnected in discharge process, to be had after adhesion corresponding
Treatment measures.For example, charging process can be disconnected immediately, charging process is terminated, can be charged after maintenance from new；Discharge process can
To send alarm, driver is reminded to drive to maintenance place and is overhauled, as being more than still to be in transport condition after setting time threshold value,
After of short duration drop power traveling, main relay is disconnected.After in addition, BMS orders, heating relay 10 is closed in certain time, point
Stream device 30 can not detect electric current, then be judged as heating unit open circuit.So as to detect heating 10 adhesion of relay and
The situation of heating unit open circuit, to adopt remedial measures in time.Play the role of circuit protection.
