The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.
The utility model discloses a power-on control device and a battery management and control system of a multichannel on-board connector, which can accurately control all the connector channels of the on-board connector of an AFE chip to be powered on simultaneously, realize the consistent power-on time of all the connector channels, thereby reducing the occurrence of the condition that the later connector channels with inconsistent plug-in time due to the inconsistent plug-in time of the on-board connector are in a live plug-in state during the plug-in, further being beneficial to reducing the occurrence of the condition that the AFE chip is damaged due to the live plug-in, and being capable of protecting the AFE chip better. The following will describe in detail.
Example 1
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electrical control device of a multi-channel board connector according to an embodiment of the utility model. The power control device of the multi-channel on-board connector described in fig. 1 may be used for any electronic component (such as all the connector channels of the on-board connector of the AFE chip in the battery management and control system) that needs to control the unified power time, and the utility model is not limited. As shown in fig. 1, the power control device of the multi-channel on-board connector may include a power control circuit and a switch control device M, where:
The first end of the power-on control circuit is used for electrically connecting the current output end of the battery connector, the second end of the power-on control circuit is used for electrically connecting the AFE chip, the third end of the power-on control circuit is connected with the switch control device M, each of all the plug-in channels contained in the battery connector is used for electrically connecting the corresponding plug-in channel in the battery connector, and the current input end of the battery connector is used for electrically connecting the battery;
The on-board connector comprises a battery connector, a switch control device M, a power-on control circuit and a power-on control circuit, wherein the power-on control circuit is used for controlling the battery to simultaneously output current to all the connector channels of the battery connector through the battery connector under the control of the switch control device M after all the connector channels of the on-board connector are inserted into corresponding connector channels of the battery connector. The number of the plugging channels of the on-board connector is equal to that of the battery connector. For example, assuming that the battery connector includes a connector channel a, a connector channel B and a connector channel C, the onboard connector includes a connector channel a matching the connector channel a, a connector channel B matching the connector channel B and a connector channel C matching the connector channel C, and the switch control device M is a button, where the connector channel a of the onboard connector is inserted into the connector channel a of the battery connector, the connector channel B of the onboard connector is inserted into the connector channel B of the battery connector, and the connector channel C of the onboard connector is inserted into the connector channel C of the battery connector, an installer installing the battery pack can press the button to turn on the power control circuit, so that the current output from the battery flows through all the connector channels of the battery connector to the corresponding connector channels of the onboard connector at the same time, and then flows from the current output end of the onboard connector to the AFE chip.
Therefore, the power-on control device for the multi-channel on-board connector described in fig. 1 can accurately control all the connector channels of the on-board connector of the AFE chip to be powered on simultaneously, so as to realize consistent power-on time of all the connector channels, thereby reducing the situation that the later connector channels with inconsistent plug-in time of the on-board connector are in a live plug-in state during the plug-in, further being beneficial to reducing the situation that the AFE chip is damaged due to the live plug-in, and being capable of protecting the AFE chip better.
In an alternative embodiment, as shown in fig. 2, fig. 2 is a schematic structural diagram of an energizing control device of another multi-channel board connector disclosed in an embodiment of the present invention, as shown in fig. 2, wherein:
The power-on control circuit comprises a switch module, wherein a first end of the switch module is electrically connected with a current output end of the connector, a second end of the switch module is electrically connected with the AFE chip, and a third end of the switch module is connected with the switch control device M. The number of the switch modules may include one or more, and the present utility model is not limited thereto. For example, assuming that the number of current input pins of an AFE chip is 3, a corresponding switching module may be provided at each current input pin of the AFE chip. Therefore, by providing the power-on control device capable of selecting the switch modules with various numbers, the switch modules with proper numbers can be selected according to the actual conditions of the AFE chip, and the applicability of the power-on control device is further improved.
In this alternative embodiment, optionally, the switching module includes a first switching device Q1, where a first end of the first switching device Q1 is electrically connected to the current output end of the socket connector, a second end of the first switching device Q1 is used to electrically connect the AFE chip, and a third end of the first switching device Q1 is connected to the switch control device M. According to the current required by the accessed AFE chip, the first switching device Q1 can be replaced, namely if the current required by the AFE chip is higher, the first switching device Q1 can be directly replaced by a switching device with larger allowable current, the requirements of electronic components with different currents can be met, and the application range of the power-on control device is wider.
In this alternative embodiment, optionally, the power-on control circuit further includes a current filtering module and a second switching device Q2, where a first end of the second switching device Q2 is electrically connected to the current output end of the connector, a first end of the current filtering module is electrically connected to a second end of the first switching device Q1, and a second end of the current filtering module is electrically connected to a second end of the second switching device Q2. The current filtering module is used for filtering instant impact current contained in the current output by the battery at the instant when the first switching device Q1 and the second switching device Q2 are turned on. Alternatively, the number of current filtering modules and the number of second switching devices Q2 may be identical to the number of current input pins of the AFE chip, which is not limited by the present utility model. Therefore, by providing the power-on control device capable of selecting the current filtering modules with diversified numbers and the second switching devices Q2 with diversified numbers, the power-on control device is beneficial to selecting the current filtering modules and the second switching devices Q2 with proper numbers according to the actual conditions of the AFE chip, and the applicability of the power-on control device is further improved. In addition, through the current filtering module, the current required to flow to the AFE chip after filtering does not contain instantaneous impact current, so that the damage of the instantaneous impact current to the AFE chip is reduced, and the AFE chip can be better protected.
In this alternative embodiment, the optional current filtering module includes, but is not limited to, a first capacitor C1, and the like capable of performing an equivalent current filtering function, where a first end of the first capacitor C1 is electrically connected to a second end of the first switching device Q1, and a second end of the first capacitor C1 is electrically connected to a second end of the second switching device Q2. At the moment when the first switching device Q1 and the second switching device Q2 are turned on, the voltage of the first capacitor C1 is zero, and at this moment, the instantaneous impact current output by the battery can be absorbed into the first capacitor C1; when the first switching device Q1 and the second switching device Q2 are turned on and the battery stably outputs the dc current, the first capacitor C1 is equivalent to an open circuit in the power-on control circuit, that is, the dc current stably output by the battery does not pass through the first capacitor C1, so that the accuracy of filtering the instantaneous impact current can be improved, and the occurrence of filtering the rest of currents (other currents are currents except the instantaneous impact current in the current output by the battery) which do not need to be filtered can be reduced, thereby further improving the applicability of the power-on control device.
In this alternative embodiment, optionally, the power-on control circuit further includes a current limiting module, wherein a first end of the current limiting module is electrically connected to the second end of the first switching device Q1, and a second end of the current limiting module is electrically connected to the first end of the first capacitor C1. The current limiting module is used for controlling the current direction of the current output by the battery to the first capacitor C1 to flow from the second end of the first capacitor C1 to the first end of the first capacitor C1. The current limiting module may be disposed between the second end of the first switching device Q1 and the first end of the first capacitor C1, or may be disposed between the second end of the second switching device Q2 and the second end of the first capacitor C1 (i.e., the first end of the current limiting module may be electrically connected to the second end of the second switching device Q2, and the second end of the current limiting module may be electrically connected to the first end of the first capacitor C1), or may be disposed between the second end of the first switching device Q1 and the first end of the first capacitor C1, and between the second end of the second switching device Q2 and the second end of the first capacitor C1 (at this time, the impedance of the two current limiting modules needs to be inconsistent). In addition, the number of the current limiting modules may be the same as the number of the first capacitors C1 in the filtering module, which is not limited by the present utility model. Therefore, through the power-on control device capable of selecting the current limiting modules with diversified numbers, the current limiting modules with proper numbers can be selected according to the actual conditions of the filtering modules, and the applicability of the power-on control device is further improved.
In this alternative embodiment, optionally, the current limiting module includes, but is not limited to, a first resistor R1 and other modules capable of performing an equivalent current limiting function, where one end of the first resistor R1 is electrically connected to the second end of the first switching device Q1, and the other end of the first resistor R1 is electrically connected to the first end of the first capacitor C1. The first resistor R1 can make the input impedance of the first end of the first capacitor C1 and the input impedance of the second end of the first capacitor C1 unequal, so that the current output by the battery can only pass through one of the first switching device Q1 and the second switching device Q2, i.e. only one of the first end of the first capacitor C1 and the second end of the first capacitor C1 is connected with the positive electrode, so that the situation that the first capacitor C1 continuously short-circuits due to the connection of the two ends of the first capacitor C1 is reduced, and the situation that the current output by the battery only flows to the first capacitor C1 but does not flow to the AFE chip is reduced, thereby being beneficial to ensuring that the AFE chip can normally work when being connected with electricity.
In another alternative embodiment, as shown in fig. 3, fig. 3 is a schematic diagram illustrating the result of a power-on control device of another multi-channel on-board connector according to an embodiment of the present invention, wherein:
The power-on control device further comprises a battery connector and an on-board connector, the battery connector is provided with a first connecting piece T1, the on-board connector is provided with a second connecting piece T2, and the first connecting piece T1 is used for connecting the second connecting piece T2 after all the connector channels of the on-board connector are inserted into the corresponding connector channels of the battery connector. The connection manner between the first connection member T1 and the second connection member T2 is a non-electrical connection manner (i.e., the remaining connection manners except for the electrical connection manner among all connection manners). In this way, by providing the power-on control device capable of performing non-electrical connection between the first connector T1 and the second connector T2, it is advantageous to prevent the board connector from falling off the battery connector after all the connector channels of the board connector are inserted into the corresponding connector channels of the battery connector, so that the connection between the board connector and the battery connector is more firm; and because the first connecting piece T1 is not electrically connected with the second connecting piece T2, the battery current can be prevented from being input into the AFE chip communicated with the second connecting piece T2 through the first connecting piece T1 in advance before being controlled by the switch control device M, so that the AFE chip can be prevented from being connected with instant impact current.
In this alternative embodiment, the first connector T1 may alternatively include, but is not limited to, any connector capable of functioning as an equivalent non-electrical connection, such as a slot, and the second connector T2 may include, but is not limited to, any connector capable of functioning as an equivalent non-electrical connection, such as a clip, and the first connector T1 is mechanically connected to the clip included in the second connector T2 via the slot included in the first connector T1. Thus, by providing the energization control apparatus capable of selecting the plurality of first connectors T1 and the plurality of second connectors T2, the application range of the energization control apparatus is wider.
The working principle of the power-on control device of the multichannel board connector in the embodiment of the utility model is as follows:
In the embodiment of the utility model, after all the plugging channels in the on-board connector of the AFE chip are plugged into the corresponding plugging channels of the battery connector of the battery, the first switching device Q1 and the second switching device Q2 are controlled to be simultaneously conducted through the switch control device M, the first capacitor C1 at the conducting moment is equivalent to a short circuit, at this moment, the first capacitor C1 stores the electric quantity corresponding to the instantaneous impact current generated by the battery at the conducting moment (namely, the first capacitor C1 filters out the instantaneous impact current), after the first switching device Q1 and the second switching device Q2 are conducted, namely, after the battery stably outputs direct current, the second end of the first switching device Q1 is electrically connected with one end of the first resistor R1 (namely, the value of the first resistor R1 of the branch where the first switching device Q1 is located is greater than the value of the first resistor R1 of the branch where the second switching device Q2 is located), and after the current output by the battery flows to the on-board connector, only flows to the second switching device Q2 but not to the first switching device Q1, and is equivalent to the situation that the first capacitor C1 is equivalent to the first capacitor C1 and the second capacitor C1 is connected with the positive end of the battery, at this moment, and the positive end of the first capacitor C is not connected with the battery, and the negative electrode of the first capacitor C is continuously connected with the battery, and the positive end of the battery occurs, the positive end of the positive capacitor and negative electrode of the battery is the negative electrode of the battery. Therefore, all the plugging channels of the on-board connector of the AFE chip can be accurately controlled to be electrified simultaneously by the electrified control device, and the consistent electrified time of all the plugging channels is realized, so that the situation that the plugging channels with the later plugging time are in a live plugging state when the plugging channels are plugged due to the inconsistent plugging time of the on-board connector can be reduced, the situation that the AFE chip is damaged due to the live plugging is reduced, the AFE chip can be better protected, and the electrified control device is short, clear in structure and low in cost.
