Description

TECHNICAL FIELD

[0001] The utility model relates to double battery isolation device technical field especially, it relates to a double battery isolation device based on wireless remote control ware control. BACKGROUND

[0002] In the prior art, the power management system of various vehicles such as automobile, recreational vehicle, UTV, ATV and ship usually relies on the power supply mode of main battery and auxiliary battery. In order to effectively manage the charging and use of the two batteries, the existing scheme mainly adopts the following ways: the parallel or disconnection operation of the main battery and the auxiliary battery is switched by a manual mechanical switch. Although this way is simple, it is very inconvenient in actual use, and the user must operate the switch personally, especially when the vehicle or equipment is far away from the operator. Some systems use ordinary relays to control the connection of the main battery and the auxiliary battery. The ordinary relay continuously consumes power during switching, and usually needs to maintain the power supply of the drive coil, resulting in additional power consumption of hundreds of milliamperes per hour. In addition, the ordinary relay generates heat when working for a long time, and additional cooling measures are needed. The power management system uses Bluetooth APP for switching control. Although wireless switching is realized by mobile phone operation, the reliability and convenience are still insufficient. The Bluetooth connection has distance limitation, and the user may need a long time to establish the connection, and there is no dedicated remote control, so the power supply cannot be quickly switched in an emergency.

[0003] In the prior art, the switching mode of manual switch has been gradually eliminated due to complex and inconvenient operation. The power consumption and heat dissipation problem of ordinary relay still cannot be completely solved. Although the Bluetooth control provides the function of wireless switching, the response speed, operation distance and convenience are still not ideal. Therefore, there is an urgent need for a more convenient, energy-saving and efficient double battery management system, which can quickly and reliably control the parallel and disconnection of the power supply through the wireless remote control, reduce the power consumption and provide better user experience.

[0033] EMBODIMENT

[0034] Please refer to Figs. 1-2 The utility model provides a technical scheme: a kind of double battery isolating device based on wireless remote controller control, comprising:

[0035] Main battery and auxiliary battery: The main battery is used to power the main systems of the vehicle or equipment, and the auxiliary battery serves as a backup power source. When the main battery is charging or low on power, the auxiliary battery can be used as a supplemental power source. The parallel or disconnected state of the main battery and auxiliary battery is controlled by a magnetic latching relay, ensuring automatic switching during battery management and avoiding the inconvenience of manual operation.

[0036] Magnetic latching relay: The magnetic latching relay is one of the core components of the device, used to switch between the main battery and auxiliary battery. Unlike traditional relays, the magnetic latching relay only needs to be powered for a short time during switching to maintain its state, reducing power consumption, saving power, and reducing relay heating. The magnetic latching relay ensures stability and efficiency when switching between the main battery and auxiliary battery.

[0037] Main control chip: The main control chip monitors the voltage of the main battery in real time to determine whether to connect or disconnect the auxiliary battery. When the main battery voltage is higher than 13.5V, the main control chip controls the magnetic latching relay to connect the auxiliary battery, allowing the main battery and auxiliary battery to charge simultaneously. When the main battery voltage is higher than 17V, the main control chip controls the magnetic latching relay to disconnect the auxiliary battery to prevent overcharging. When the main battery voltage is lower than 12.8V, the main control chip also disconnects the auxiliary battery to prevent mutual power consumption between the main and auxiliary batteries, ensuring efficient operation of the battery system.

[0038] Wireless remote control: The wireless remote control is the remote control unit of the device, allowing users to operate it from a distance. The remote control uses 433MHz and 2.4GHz wireless communication modules, and users can control it through three keys on the remote control. The "ON" key is used to manually connect the main battery and auxiliary battery, the "OFF" key is used to manually disconnect the battery connection, and the "AUTO" key is used to switch to automatic mode, allowing the main control chip to automatically manage and switch based on the battery voltage state.

[0039] Digital display tube: The digital display tube displays the voltage of the main battery in real time, with a display accuracy of ±0.1V. Users can understand the working state of the battery through intuitive voltage readings, allowing them to determine whether to charge or switch power sources in a timely manner. The display tube provides users with convenient and easy-to-understand battery information, ensuring that users can always monitor the battery status and avoid equipment downtime due to low battery levels.

[0040] Buzzer: When the main battery voltage is lower than 11V, the buzzer will emit a continuous 60-second alarm sound, reminding users that the main battery is low on power. This can effectively prevent the main battery from being completely depleted, ensuring that users can charge or switch to the auxiliary battery in a timely manner, avoiding situations where the vehicle or equipment cannot start due to low battery levels.

[0041] Working principle: The dual-battery isolation device relies on the real-time detection of the main battery voltage by the master chip, and realizes the automatic or manual switching of the main battery and the auxiliary battery through the magnetic latching relay. In the automatic mode, when the master chip detects that the voltage of the main battery is higher than 13.5V, the master chip will control the magnetic latching relay to connect the auxiliary battery, so that the two batteries are charged at the same time. This state ensures that when the vehicle or equipment is running, the battery can effectively allocate charging resources and maintain sufficient power of the two batteries. When the voltage of the main battery further rises and exceeds 17V, the master chip will automatically control the magnetic latching relay to disconnect the auxiliary battery, thereby preventing the auxiliary battery from being overcharged and avoiding damage or shortening the service life of the auxiliary battery. Conversely, when the voltage of the main battery drops below 12.8V, the master chip will control the magnetic latching relay to disconnect the auxiliary battery, preventing the two batteries from consuming each other's power. It is suitable for long-term parking or equipment not in use, protecting the remaining power of the main battery and preventing accidental depletion. In the manual mode, the user can remotely control the connection state of the battery through the wireless remote control. When the "ON" key of the remote control is pressed, the master chip will instruct the magnetic latching relay to connect the main battery and the auxiliary battery, forcing the two batteries to be connected in parallel for power supply or charging. It is suitable for manual control of the operation of the battery under certain conditions. When the "OFF" key is pressed, the master chip controls the magnetic latching relay to disconnect the main battery and the auxiliary battery, ensuring that the two circuits are completely separated and avoiding power consumption. The user can also switch the system back to automatic mode by pressing the "AUTO" key. At this time, the master chip will automatically manage the connection or disconnection of the battery according to the real-time detected voltage state, providing more intelligent and convenient power management.

[0042] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technology content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments made in accordance with the technical essence of the present application shall fall within the protection scope of the present application.
