Description
Technical Field
The application relates to the field of signal acquisition of battery modules, in particular to a temperature acquisition board for a battery module.
Background
The battery module includes numerous series-parallel battery monomer of putting together, in order to monitor battery module's temperature to guarantee the electrical safety, need install temperature probe in the module. In order to process the raw data acquired by the temperature probe to obtain the temperature value at the temperature probe, a temperature acquisition chip connected with the temperature probe circuit is required to be configured. The specific parameter (such as resistance value) of the temperature probe can be changed due to the temperature change, and the change of the parameter can influence the temperature acquisition chip
In order to make the temperature value processed by the temperature acquisition chip equal to the actual temperature value at the temperature probe, a voltage dividing resistor needs to be arranged in a connecting circuit between the temperature probe and the temperature acquisition chip. Under the condition that the model of the temperature acquisition chip is not changed, if the specification of the temperature probe is changed, the divider resistor with another resistance value is replaced, and the temperature value obtained by the temperature acquisition chip can be ensured to be an accurate value.
In production, the specifications of the battery modules are various, and different temperature probes are generally configured for the battery modules with different specifications. If when the temperature of the battery module is detected each time, the original voltage-dividing resistor is correspondingly dismantled and a new voltage-dividing resistor is connected, the operation is very inconvenient and the efficiency is low.
Moreover, in order to improve the convenience of temperature acquisition, PACK manufacturers of some battery modules generally set the temperature acquisition chip on the acquisition board, and set a plug-in connector connected to the temperature acquisition chip on the acquisition board, a voltage divider resistor is directly set on the acquisition board and connected to the connection circuit of the temperature acquisition chip and the plug-in connector, and a temperature probe of the battery module is connected to a lead-out plug through a cable or a PCB transition plate. During temperature measurement, the butt joint plug and the leading-out plug are mutually inserted, so that the circuit connection of the temperature probe and the temperature acquisition chip is realized. Although the temperature acquisition device with the structure is convenient to operate, the voltage dividing resistor is directly integrated on the acquisition plate and is difficult to replace or even impossible, so that the temperature acquisition device can only be matched with a temperature probe with a specific specification for use.

Furthermore, the technical features, aspects or characteristics described herein may be combined in any suitable manner in one or more embodiments. It will be readily appreciated by those of skill in the art that the order of the steps or operations of the methods associated with the embodiments provided herein may be varied. Thus, any sequence in the figures and examples is for illustrative purposes only and does not imply a requirement in a certain order unless explicitly stated to require a certain order.

Fig. 1 shows a preferred embodiment of the temperature collecting plate for a battery module according to the present invention, and as with the conventional structure, the circuit board also includes a plate body 1, a temperature collecting chip 2, a docking plug 3, and a temperature collecting circuit 4 connecting the aforementioned docking plug and the temperature collecting chip are disposed on the plate body 1, and the docking plug 3 is used for docking a plug led out from a battery pack to connect a temperature probe disposed in the battery pack with the aforementioned temperature collecting chip 2.
The key improvement of this application lies in that a selection switch 7 and two divider resistors with different resistance values are further disposed on the plate body 1, and for facilitating the clear description of the technical solution of this embodiment, the two divider resistors are respectively referred to as a first divider resistor 5 and a second divider resistor 6. In practical applications, an operator can selectively connect the first voltage-dividing resistor 5 or the second voltage-dividing resistor 6 to the temperature acquisition circuit 4 by controlling the selection switch 7.
Specifically, the resistance of the first divider resistor 5 is 10K Ω, and the resistance of the second divider resistor 6 is 100K Ω.
When the acquisition board is used for acquiring the temperature of the battery in the battery module, the divider resistor with the corresponding resistance value can be selected according to the specification of the temperature probe in the battery module to be connected into the temperature acquisition circuit 4 between the butt-joint plug 3 and the temperature acquisition chip 2, so that the temperature value obtained by processing through the temperature acquisition chip 2 is the actual temperature value of the battery module. Such as: if a temperature probe in a certain battery pack should be matched with a voltage dividing resistor of 10K Ω, the selection switch 7 needs to be controlled to connect the first voltage dividing resistor 5 to the temperature acquisition circuit 4, and if a second voltage dividing resistor 6 with a resistance of 100K Ω is mistakenly connected to the temperature acquisition circuit 4, the temperature value obtained by processing the temperature acquisition chip 2 is inaccurate because the voltage dividing resistor is not matched with the temperature probe and the temperature acquisition chip 2.
The selection switch 7 may adopt various structural forms, and the embodiment is specifically such a structure: the selector switch 7 includes a switch case 706, four terminals, which are referred to as a first terminal 701, a second terminal 702, a third terminal 703, and a fourth terminal 704, respectively, for convenience of description, and a pin 705.
The first terminal 701, the second terminal 702, the third terminal 703 and the fourth terminal 704 are all disposed on the side of the switch housing 706, and the four terminals are spaced apart. The paddle 705 is movably mounted in the switch housing 706, and the paddle 705 has a paddle end that extends outside the switch housing.
In fig. 1, the right end of the first voltage dividing resistor 5 is connected to the first terminal 701, the right end of the second voltage dividing resistor 6 is connected to the second terminal 702, and the left end and the third terminal 703 of the first voltage dividing resistor 5 are connected in parallel to the left end and the fourth terminal 704 of the second voltage dividing resistor 6, and then connected in series in the temperature collecting circuit 4
Referring to fig. 1, when the pin 705 is moved upward in fig. 1 to a first operating position (shown by a dotted line) by an operator, the pin 704 is in simultaneous electrical contact with the first terminal 701 and the third terminal 703 and is separated from the second terminal 702 and the fourth terminal 704. At this time, the first terminal 701 and the third terminal 703 are conducted to each other through the pin 704, and the first voltage dividing resistor 5 is connected to the temperature acquisition circuit 4.
When the pin 705 is moved down in fig. 1 to the second operating position by an operator, the pin 704 is in simultaneous electrical contact with the second terminal 702 and the fourth terminal 704 and is separated from the first terminal 701 and the third terminal 703. At this time, the second terminal 702 and the fourth terminal 704 are conducted to each other through the pin 705, and the second voltage dividing resistor 6 is connected to the temperature collecting line 4.
Obviously, in order to match the collecting plate with temperature probes of more specifications, a third voltage dividing resistor with the resistance value of neither 10K Ω nor 100K Ω can be further arranged on the plate body 1. The operator can select the first voltage dividing resistor 5, the second voltage dividing resistor 6 and the third voltage dividing resistor to be connected to the temperature collecting circuit 4 by setting other forms of selection switches 7.
The temperature acquisition chip 2 is a commercially available product, and the model thereof is CY8C4247LQI-BL 483.
The above embodiments are only for illustrating the technical concepts and features of the present application, and the purpose of the embodiments is to enable people to understand the content of the present application and implement the present application, and not to limit the protection scope of the present application.
