A battery blind connection protection device is connected between the vehicle assembly 1 and the battery 2. The battery blind connection protection device includes a control switch 3, a control switch 4, a control switch 5, a diode 6, and a diode 7. Diodes 6 and 7 are electrically connected to the battery. Control switches 3 and 5 are connected in series with diode 6, and control switches 5 are connected in series with diode 7. Control switches 3, 4, and 5 are electrically connected to the vehicle assembly 1.
[0027] As a further explanation of the present invention, the positive terminal of diode 6 is electrically connected to the positive terminal of the battery, and its negative terminal is used to electrically connect to control switch 3 and control switch 5. The positive terminal of diode 7 is electrically connected to the negative terminal of the battery, and its negative terminal is used to electrically connect to control switch 4.
[0028] As a further explanation of the present invention, the positive terminal of diode 6 is electrically connected to the negative terminal of the battery, and its negative terminal is used to be electrically connected to control switch 3 and control switch 5. The positive terminal of diode 7 is electrically connected to the positive terminal of the battery, and its negative terminal is used to be electrically connected to control switch 4.
[0029] As a further explanation of the present invention, a light-emitting diode 8 is provided between the positive and negative terminals of the vehicle equipment 1, and the light-emitting diode lights up when the vehicle equipment 1 is powered on normally.
[0030] As a further explanation of the present invention, the control switch 3, control switch 4, and control switch 5 have the same structure, and the control switch 3 is either a relay or a contactor coil. Example
[0031] When connecting the battery, the left side is negative and the right side is positive, as follows: Figure 3 As shown, control switch 3, control switch 4, and control switch 5 are relays; in this embodiment, diode 1 and diode 2 are both in normal condition.
[0032] Because diode 6 is not energized, the relay coils in control switches 1-3 and 3-5 are in an open state, and the negative terminal of battery 2 is connected to the negative terminal of vehicle equipment 1.
[0033] When the relay coil in control switch 24 is energized by diode 27, the relay coil in control switch 24 is engaged, and the positive terminal of battery 2 is connected to the positive terminal of vehicle equipment 1.
[0034] In this embodiment, LED 8 lights up, and vehicle equipment 1 is powered on normally. Example
[0035] When connecting the battery, the left side is positive and the right side is negative, such as Figure 4 As shown, control switch 3, control switch 4, and control switch 5 are relays; in this embodiment, diode 1 and diode 2 are both normal: because diode 6 is energized, the relay coils in control switch 3 and control switch 5 are engaged and in working state, and the positive terminal of battery 2 is connected to the positive terminal of vehicle equipment 1.
[0036] Because diode 27 is not energized, the relay coil in control switch 24 is in an open state. The negative terminal of battery 2 is connected to the negative terminal of vehicle equipment 1 via control switch 35, which is the relay.
[0037] In this embodiment, LED 8 lights up, and vehicle equipment 1 is powered on normally. Example
[0038] When the battery is connected with the left side positive and the right side negative, diode 27 is normal. Diode 16 is damaged and short-circuited. Figure 5 The relay coils in control switches 1-3 and 3-5 are not energized due to the damage of diode 1-6. The relays in control switches 1-3 and 3-5 are in the open state, and the positive terminal of battery 2 is connected to the negative terminal of vehicle equipment 1.
[0039] Because diode 7 is not energized, the relay coil in control switch 24 is in the open state, but the negative terminal cannot be connected to the positive terminal of vehicle equipment 1 via relay 3.
[0040] In this embodiment, LED 8 is not lit, vehicle equipment 1 cannot be powered on normally, and vehicle equipment 1 is safe. Example
[0041] When the battery is connected with the left side positive and the right side negative, diode 6 is normal. Diode 7 is damaged and broken down. Figure 6: Control switch one 3 and control switch three 5 relay coil is not energized by diode one 6, control switch one 3 and control switch three 5 relay coil is in open state, battery 2 positive pole is connected to vehicle equipment 1 negative pole cable.

[0045] Control switch two 4 relay coil is not energized by diode two 7, control switch two 4 relay coil is in open state, battery 2 negative pole is not connected to vehicle equipment 1 negative pole through control switch three 5 relay coil.
[0046] In this embodiment, light emitting diode 8 is not on, vehicle equipment 1 cannot be normally powered up, vehicle equipment 1 is safe. Embodiment
[0047] When connecting battery left negative right positive, diode two 7 is normal, diode one 6 is damaged and breakdown, such as Figure 8 : Control switch one 3 and control switch three 5 relay coil is not energized by diode one 6, control switch one 3 and control switch three 5 relay coil is in open state, battery 2 negative pole is connected to vehicle equipment 1 negative pole cable.

[0051] The control switch 4 relay coil is not energized due to the damage of diode 2, the control switch 4 relay coil is in the off state, and the positive electrode of the storage battery 2 cannot pass through the relay coil of the control switch 3 to the positive electrode cable of the vehicle equipment 1.
[0052] In this example, the light-emitting diode 8 is not lit, the vehicle equipment 1 cannot be normally powered on, and the vehicle equipment 1 is safe. Embodiment
[0053] When the left negative and right positive of the storage battery are connected, both the diode 1 6 and the diode 2 7 are damaged and broken down, for example, Figure 10 : The control switch 3 relay coil and the control switch 5 relay coil are not energized due to the diode 1 6, the control switch 3 relay coil and the control switch 5 relay coil are in the off state, and the negative electrode of the storage battery 2 is connected to the negative electrode cable of the vehicle equipment 1.
[0054] The control switch 4 relay coil is not energized due to the damage of diode 2, the control switch 4 relay 2 is in the off state, but the positive electrode of the storage battery 2 cannot pass through the relay 3 to the positive electrode cable.
