Embodiment
As shown in Figure 1, a kind of automatic equalization battery tray of the utility model, including pallet, it is provided with the pallet
Multiple spaces for vertical placing battery, the space bottom for vertical placing battery are provided with cathode contact 4 and bear
Pole contact 16；Further include balance controller 5, the cathode connection cable terminals that the cathode contact 4 passes through cathode connection cable 1
Son 2 is electrically connected with balance controller positive terminal row 6.The cathode contact 16 by after 3 parallel connection of anode parallel connection copper bar with it is balanced
The always negative interface 7 of controller is connected；Battery plus-negative plate detection module is provided with the balance controller.
Further, as shown in Fig. 2, the battery plus-negative plate detection module includes light emitting diode 9, each battery
Cathode contact is connected by cathode connection cable 1 with the balanced switching switch of detection, the detection of the balanced switching switch 8 of detection
Pattern contact 801 is connected with 9 anode of light emitting diode, and 9 cathode of light emitting diode is connected with total negative interface 7；It is described
The balanced mode contact of the balanced switching switch 8 of detection is connected with cathode parallel connection copper bar 13；Each battery corresponds to one luminous two
Pole pipe 9.Battery reversal connection alarm 10 is connected between the light emitting diode 9 and always negative interface 7, battery is anti-in present embodiment
Device 10 taking alarm uses buzzer.
Further, the always negative interface 7 is connected with inputting negative interface 11, exporting negative interface 12 respectively；It is described just
Copper bar 13 extremely in parallel is connected with inputting positive interface 14, exporting positive interface 15 respectively.So if necessary between different pallets
Battery will also realize equilibrium, can connect the input interface of the output interface of balance controller and another pallet balance controller
Pick up and.The anode of all pallets is all connected to together by cathode parallel connection copper bar 13 after connection, all batteries
Anode links together also by total negative interface 7, realizes the equilibrium of all batteries.
As shown in Fig. 2, when battery is inverted into pallet, the positive and negative anodes contact of pallet is connected with anode with anode.
Afterwards, anode is connected in parallel by anode parallel connection copper bar 3, and is connected by always bearing interface 7 with balance controller 5.This implementation
In mode, there is a winding displacement of 24 pins in the upper and lower part of pallet respectively, and every single line of winding displacement can respectively and correspondence position
Cathode contact 4 is connected, and is connected by cathode connection cable wire connection terminal 2 with balance controller 5.Use preceding first balance controller
5 detection equilibrium switching switch 8 is adjusted to detection pattern so that the detection mould of the switching switch 8 balanced with detection of cathode connection cable 1
Formula contact 801 is connected, and being adjusted to balanced mode after all batteries install starts equilibrium.Switching principle is as follows, in detection pattern
