[0023] Reference Figure 1 As shown, the utility model relates to an electric bicycle battery pack function detection system, including a detection device and a host computer. The detection device and the host computer are connected.

The detection device includes a signal control module, a load control module, a charging control module and an MCU module; the MCU module is connected to the signal control module, the load control module and the charging control module respectively. During the actual detection process, the host computer is used to send detection instructions (including discharge detection instructions and charging detection instructions) to the MCU module in the detection device. The MCU module can return the detection results to the host computer, and the staff can observe the detection results through the display screen provided by the host computer.

[0024] Furthermore, the battery pack of this embodiment includes a charging port and a discharging port, and the detection device also includes a detection port for the battery pack charging port and a detection port for the battery pack discharging port. The charging port is correspondingly connected to the detection port of the battery pack charging port (specifically connected through the pin pins of the connector), and the discharging port is correspondingly connected to the detection port of the battery pack discharging port (specifically connected through the pin pins of the connector).

[0025] Furthermore, the signal control module of this embodiment is connected to the detection port of the battery pack discharge port. The signal control module's function is to provide a high / low level to the pin corresponding to the detection port of the battery pack discharge port, simulating the presence of the battery pack on the e-bike (i.e., the battery pack is in place) and simulating the e-bike key signal. In short, the signal control module functions as a start-up control for the e-bike, as subsequent discharge detection is only possible with the control of the signal control module. The signal control module of this embodiment is a photocoupler.

[0026] Furthermore, the detection device of this embodiment also includes several different loads ( Figure 1 The figure shows three loads, load 1, load 2, and load 3, each having different discharge powers or resistance values, for simulating different discharge conditions.

The load control module in this embodiment is a first relay. Figure 1 For example, the load control module of this embodiment may include three first relays for controlling three loads (i.e., load 1, load 2, and load 3). Specifically, the MCU module controls which load is turned on or off through the load control module, applying different loads to the battery pack, thereby implementing discharge detection for the corresponding loads.

[0027] Furthermore, the loads in this embodiment include, but are not limited to, a preset power load simulating an electric bicycle, a headlight load, and a motor load. Because discharge detection results vary with different loads, this embodiment includes multiple loads to meet actual detection requirements and achieve results as close to actual results as possible.

[0028] Furthermore, the detection device of this embodiment also includes a charger connected to the charging control module, and the MCU module controls the charger through the charging control module to realize charging detection of the battery pack; the charging control module is a second relay used to control the opening or closing of the charger.

[0029] Furthermore, the detection device is provided with a communication module, and the detection device is connected to the host computer for communication through the communication module. The communication module includes a wired communication unit and a wireless communication unit. The wired communication unit is the host computer communication interface, and the wireless communication unit is a Bluetooth unit.

[0030] Furthermore, the host computer communication interface unit of this embodiment is an Ethernet interface or a USB interface.

[0031] Further, the MCU module of the present embodiment is provided with a main control chip, and the main control chip is an STM32 series single-chip microcomputer or an MSP430 series single-chip microcomputer. In other embodiments, the main control chip can be a single-chip microcomputer of other models or other series.
