Control device and control method for charging and discharging motor

[0071] Example 1

[0072] Design a control device to control the charging and discharging machine, and use the control device to control the charging and discharging machine to realize automatic repair for the 6DZM12 battery of the electric bicycle.

[0073] This embodiment is based on the commonly used 320V charging and discharging machine with 3A charging and 5A discharging in the market (programming charging and discharging of battery packs with 18 12V batteries connected in series) is used as the basis, and the control device is connected with the existing charging and discharging machine. The device controls the charging and discharging process of the charging and discharging machine.

[0074] The existing charging and discharging machine includes a control module 1, a discharging module 2, a charging module 3, and a housing 4. The charging module 3 and the discharging module 2 are internally connected to the control module 1, and the output terminals of the charging module 3 and t

[0082] The technical improvement of the first embodiment is to change the color lamp as the digital display device 7 to a liquid crystal display, and its signal input terminal is connected to the signal display control terminal of the microprocessor 1a through the peripheral circuit 1b in the control device. It reflects the real-time voltage and the real-time value of the charging current of the charged battery 6, and the normal and abnormal stop of the charging and discharging integrated machine.

[0083] The digital liquid crystal display 7 displays the real-time voltage and the real-time value of the charge / discharge current of the charged battery 6 by displaying every 5 seconds and switching the display every 2 seconds when the charging and discharging machine is normally charged; when the repair charging procedure is completed normally, The digital liquid crystal display 7 displays all 8; when the battery 6 is charged with 2.5Ah and the voltage at both ends o

[0086] On the basis of the second embodiment, a temperature sensor 5 is added.

[0087] The temperature sensor 5 is arranged outside the housing of the control device, and its signal terminal is connected to the temperature monitoring input terminal of the microprocessor 1a through the peripheral circuit 1b; the temperature sensor 5 inputs the external ambient temperature to the microprocessor 1a According to the temperature data, the control device controls the charging and discharging machine to realize the compensation of the charging capacity of the storage battery 6.

[0088] The control device controls the charging module 3 of the charging and discharging machine to automatically perform temperature compensation for the remaining charge of the battery 6. With 25°C as the reference, it is designed to change by one level every time the temperature change exceeds 5°C to classify the remaining charge of the battery 6 Level compensation. When the external working e
