Have you ever been frustrated by having to frequently remove the seat and manually turn the battery on and off?
Now, as new demands have emerged in the lithium-ion golf cart battery market, we've addressed our customers' pain points by introducing a convenient remote battery on/off feature-which we call the "Remote Power Switch."
Now, you no longer need to remove the seat; you can turn the battery on and off using the mobile app or the power button on the battery status display. Let's take a look at how it works.
What Is Remote Power Control?
Remote Power Control is a control feature integrated into smart lithium-ion battery systems. It allows users to turn the battery ON and OFF via external control devices-such as a mobile app, battery status display, or wireless control button-without having to physically touch the battery itself.
In the past, we had to lift the seat cushion on a golf cart before we could manually turn the battery ON or OFF. For users who operate golf carts daily, this procedure is not complicated, but it can become tedious over time.
This is especially true in certain scenarios-such as private communities, golf courses, resorts, and property patrol vehicles-where the vehicle needs to be started and stopped frequently. Repeatedly removing the seat not only makes operation more difficult but also detracts from the user experience.
How Does Remote Power Control Work?
Let's simplify this complex issue. The basic principle can be understood as follows: a communication protocol transmits the user's on/off commands to the smart battery management system inside the battery, and the BMS then controls the internal electronic switches to enable remote activation and deactivation of the battery.
When a user sends an ON/OFF command via a mobile app, the battery status display, or a wireless control button, the control signal is transmitted to the BMS inside the battery via communication protocols such as Bluetooth, CAN, or UART.
Upon receiving the command, the BMS does not execute it immediately. Instead, it first checks the current battery status-for example, whether there is overvoltage, undervoltage, overcurrent, a short circuit, or abnormal temperature. If the battery status is normal, the BMS controls the internal MOSFET (electronic switch) to turn on or off, thereby enabling or disabling the battery's output.
Key Features of a Remote Power Control System
Rather than calling it a "remote power switch," it would be more accurate to refer to it as a "remote intelligent control system." For lithium-ion battery-powered golf carts, a comprehensive Remote Power Control System should have the following core functions:
1. Remote Battery ON/OFF Control
This is the feature we'll be focusing on today. You can turn the battery on or off using the app on your phone, or via the display.
2. Smart Battery Display
The Remote Power Control system is used in conjunction with an LCD battery status display, allowing users to view the battery's operating status directly from the driver's seat. The display provides real-time feedback on the battery's SOC, voltage, current, temperature, and fault information, enabling users to gain a more intuitive understanding of the battery's current status.
3. Bluetooth App Monitoring
Users can connect to the mobile app via Bluetooth to view more detailed battery performance data and control the battery remotely. Due to the limited size of the display, only basic information is shown. The app, however, can access more in-depth data, such as battery health, cycle count, cell voltage, and BMS protection logs.
4. Fault Diagnosis and Protection Alerts
The Remote Power Control system is deeply integrated with the BMS. It not only controls the battery switch but also monitors the battery's protection status in real time.
If a battery anomaly occurs (such as overvoltage, undervoltage, overcurrent, high temperature, low temperature, or communication failure), the system will promptly display the fault information on the screen or via the mobile app, allowing users to quickly identify the cause of the problem and thereby reduce the time required for manual inspection.
5. CAN Communication Support
For high-end golf carts and OEM projects, CAN communication is a key feature of the Remote Power Control system.
Using the CAN protocol, the battery can exchange data with the vehicle controller and instrument cluster, enabling deeper system integration. The vehicle can read the battery's SOC, operating status, and fault information, thereby improving compatibility and intelligence between the battery and the vehicle as a whole.
6. Low-Power Sleep and Wake-Up Features
When the vehicle is parked for an extended period, the system automatically enters a low-power state, effectively reducing standby power consumption and minimizing battery drain during long-term storage. When users need to use the vehicle, they can quickly wake up the battery and restore it to normal operating status via the mobile app, buttons on the in-vehicle display, or wireless control.
Remote Power Control vs Traditional Battery Switch
Let's take a look at a side-by-side comparison of traditional manual switches and remote switches:
| Comparison | Traditional Battery Switch | Remote Power Control |
|---|---|---|
| Operation Method | Manual operation by pressing or turning a physical switch on the battery | Remote control through a mobile app, battery display, or wireless button |
| Operation Location | Requires opening the seat or battery compartment to access the battery | Allows users to control the battery directly from the driver's position |
| User Experience | Provides basic ON/OFF switching only | Provides a smarter and more convenient battery control experience |
| Battery Status Monitoring | Usually cannot display real-time battery information | Can display SOC, voltage, current, temperature, and other battery data |
| Fault Information | No active fault notification | Can display BMS protection status and fault codes through APP or display |
| Communication Capability | No communication with external devices | Supports Bluetooth, CAN, UART, and other communication protocols |
| System Integration | Works as an independent mechanical switch | Integrated with BMS, display systems, and vehicle control systems |
| Smart Functions | Limited to manually turning the battery on or off | Supports remote control, sleep mode, wake-up function, and intelligent diagnostics |
