[0002] In the field of energy storage, for example, user energy storage, commercial energy storage or large industrial energy storage system, all cannot leave battery control system. Because any form of energy storage system, all cannot leave the temporary storage, buffering capacity of battery, therefore the stability of battery control system has very important influence on the normal continuous operation of the whole energy storage system.
[0003] The existing battery control system can be self-started under some special application requirements, for example, self-checking start after troubleshooting, which is usually to save manual restart time and then quickly respond. Usually, the battery control system has a visual indication device, for example, when it starts, the start indicator light will light up to prompt the outside staff that the system is in working condition. In the production process of the hardware device of the battery control system, a pre-shipment static stability test link is usually included, that is, a large number of products are placed for a period of time to observe whether they will automatically start. If the product quality is not up to standard, there may be abnormal situations such as internal electronic components leaking electricity, which may automatically activate the self-starting program, and the staff need to observe and record whether there is an abnormal self-starting situation within the static stability test time, and then ensure the quality of the product out of the factory.

[0023] Figure 2 It is a circuit diagram of the photoelectric detection circuit of the device. DETAILED DESCRIPTION
[0024] The technical scheme of the utility model embodiment will be explained and described below in combination with the drawings of the utility model embodiment. The following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
[0025] The terms "first", "second", etc. in the specification and claims and the above drawings are used to distinguish different objects, not to describe a specific order. In addition, the term "includes" and any variation thereof is intended to cover non-exclusive inclusion. For example, the process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or optionally also includes other steps or units inherent to the process, method, product or device.
[0026] As Figure 1As shown, the PCB is installed in the shell, and the shell is provided with a magnetic fixing part, which can help the staff to quickly install the device directly on the metal shell of the battery control product or on the metal frame of the battery control product. At this time, the detection hole on the shell is aligned with the start indicator light of the detected product, and the phototransistor N opposite the start indicator light transmits light. Since the phototransistor N has photoelectric conversion capability, when the battery control product is self-started during the static test, the phototransistor N can receive the light of the start indicator light, thereby generating current and voltage. The voltage is the global opening voltage of the device.
[0027] As shown in Figure 2 As shown, the AC power supply is connected to the two AC input terminals of the single rectifier bridge through the L terminal and the N terminal. The single rectifier bridge is connected by four diodes in the form of a bridge, and each two diodes are connected in series to conduct half a cycle. The positive half cycle and the negative half cycle of the power supply are both output as two positive half cycles. A voltage stabilizing tube is connected in parallel between the two DC output terminals of the single rectifier bridge. When the output voltage of the single rectifier bridge is less than or equal to the rated stable voltage of the voltage stabilizing tube, the voltage across the voltage stabilizing tube is the output voltage of the single rectifier bridge. When the output voltage of the single rectifier bridge is greater than the rated stable voltage of the voltage stabilizing tube, the voltage across the voltage stabilizing tube is the rated stable voltage of the voltage stabilizing tube. A capacitor C1 is connected in parallel across the voltage stabilizing tube. The capacitor C1 is used for energy storage and filtering to reduce the degree of voltage output pulsation. Specifically, when the voltage across the voltage stabilizing tube rises in a sinusoidal manner, the capacitor C1 charges, and when the voltage across the voltage stabilizing tube falls in a sinusoidal manner, the capacitor C1 discharges. The capacitor C1 is used as an energy storage filter in the circuit, and the charging and discharging of the capacitor C1 improves the degree of pulsation of the output voltage.
[0028] The photoelectric detection circuit includes a phototransistor N for sensing external light signals, a light prompting circuit and a sound prompting circuit controlled by the phototransistor N to change the on / off state, wherein the light prompting circuit includes an amplification transistor T1, an electromagnetic relay coil KM connected in series with the emitter of the amplification transistor T1, a time relay coil KT, and a warning light diode M; the sound prompting circuit includes a buzzer S, a delay off switch KT' connected in series with the buzzer S, and a normally open switch KM'; wherein the electromagnetic relay coil KM controls the on / off of the normally open switch KM', and the time relay coil KT controls the on / off of the delay off switch KT'.
[0029] When the photo transistor N receives the light of the starting indicator light, it is turned on under the action of the power supply voltage, at this time, since the emitter of the photo transistor N is connected with the base of the amplifying transistor T1, the amplifying transistor T1 is also turned on under the above action, at this time, the electromagnetic relay coil KM and the time relay coil KT are powered, and the warning light diode M in series with the two emits light, the light intensity of which is far more than that of the starting indicator light of the product, and by selecting the warning light diode M with a specific color, the warning effect can be further enhanced.
[0030] Since the electromagnetic relay coil KM controls the on / off of the normally open switch KM', and the time relay coil KT controls the on / off of the time delay open switch KT', when the above two coils are powered, the normally open switch KM' and the time delay open switch KT' are closed, at this time, the buzzer S is powered and emits a warning sound, which reminds in the sound dimension.
[0031] Since the time delay open switch KT' is used, after a period of time after the light signal of the starting indicator light disappears, the buzzer S can still emit sound for a period of time, avoiding the staff from missing the identification.
[0032] In addition, the hole wall of the detection hole is provided with an elastic light shielding rubber ring, which is used to shield external interference light and improve the sensing accuracy of the starting indicator light of the detected product.
[0033] The above is only the preferred embodiment of the present application and the explanation of the applied technical principles, and those skilled in the art should understand that the protection scope involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and also covers other technical solutions formed by the combination of the above technical features or their equivalent features without departing from the above disclosed concept. For example, the above features are replaced with the technical features disclosed in the present application (but not limited to) with similar functions to form technical solutions.
[0034] In addition, although some specific implementation details are included in the above discussion, these should not be interpreted as limiting the scope of the present application. Some features described in the context of separate embodiments can also be combined for implementation in a single embodiment. Conversely, various features described in the context of a single embodiment can also be implemented separately or in any suitable sub-combination in multiple embodiments.
