Abstract
An undervoltage continuous-running control device of an electric bicycle includes a control chip P, an undervoltage protection point A arranged on the control chip P, and a battery C. The utility model is improved in that a continuous-running control point B is also arranged on the control chip P; the continuous-running control point B is connected with the undervoltage protection point A in parallel and then is connected with the battery C in series; the continuous-running control point B is connected with an indicator light LED2 and the battery C in series; the undervoltage protection point A is connected with an indicator light LED1 and the battery C in series. In the utility model, the principles of voltage recovery and small current discharging of the battery are utilized; under the undervoltage state of the battery, the speed of the bicycle is slowly reduced and the undervoltage continuous-running mileage is prolonged by 10 to 15 kilometers which are 2 to 3 times as the undervoltage continuous-running mileage of the existing electric bicycle; therefore, the phenomena of frequently charging and stopping as well as getting off the bicycle to push are avoided, and a user can slowly ride the bicycle to home. When the electric bicycle continuously runs steadily and slowly, and the indicator lights twinkle ceaselessly to remind the user of timely charging.
Description
Technical field
The utility model relates to a kind of control setup of Electrical Bicycle, relates to a kind of under-voltage control setup that continues of Electrical Bicycle specifically.
Background technology
Electrical Bicycle commonly used in the process of moving; cell pressure will reduce gradually; when cell pressure reaches the 42V that Electrical Bicycle sets ± 1V under-voltage value; controller enters the under-voltage protection state automatically; Electrical Bicycle ride in the time of then can occurring and to preshoot, the time and pause the time towards the time phenomenon of stopping; finally can not travel, in this case, driver have to get off implementation, very tired and trouble.The under-voltage mileages of continuation that how to keep battery-driven car is a technical matters anxious to be solved always.At present, a kind of Electrical Bicycle with two under-voltage functions is arranged, it is provided with two under-voltage points, when battery-driven car drives at first under-voltage, master cock is placed on the standby under-voltage point, make Electrical Bicycle under under-voltage situation, can continue again to travel 3～5 kilometers, and remind the user in time to charge.In real life, the user gets back on the first under-voltage point often forgetting after the charging master cock dialled, this master cock places on the standby under-voltage point always, if it is under-voltage to occur battery once more, when Electrical Bicycle travels forward towards the time stop, up to riding, can only get off implementation, very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of under-voltage control setup that continues of Electrical Bicycle.
For solving the problems of the technologies described above; the under-voltage control setup that continues of a kind of Electrical Bicycle of the present utility model; comprise control chip P, be arranged on under-voltage protection point A, battery C on the control chip P; its improvement is: also be provided with the controlling point B that continues on the described control chip P, be in series with battery C after this continue controlling point B and described under-voltage protection point A are in parallel again.
As a kind of improvement of the present utility model, the described controlling point B that continues connects with indicator lamp LED2, battery.
As another kind of improvement the of the present utility model, described under-voltage protection point A connects with indicator lamp LED1, battery.
As further improvement of the utility model, described indicator lamp LED1, LED2 are separately positioned on the instrument carrier panel.
The utility model utilizes the voltage rise of battery and the principle of low discharging current, on control chip, also have additional the controlling point B that continues, its under-voltage value is 43.5V, when cell pressure drops to 43.5V, control chip P enters the under-voltage program that continues automatically, battery begins low discharging current, and at this moment, cell pressure will go back up to 44～45V, low discharging current process along with battery, Electrical Bicycle speed slowly reduces, and the under-voltage speed of continuing is 8～10 kilometers/hour, and the speed of a motor vehicle is more and more slower, in the time of can not occurring towards the time phenomenon of stopping, when steadily continuing at a slow speed, indicator lamp constantly glimmers, and reminds the user in time to charge.When battery current slowly discharged into 2A by 10A, cell pressure dropped to 41V, and Electrical Bicycle stops to travel.The under-voltage control setup that continues of the present utility model is simple in structure, and dependable performance is neither damaged battery and can be prolonged under-voltage mileages of continuation again, and under under-voltage condition, the user needn't carry out, and can travel at a slow speed and go home.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the under-voltage control setup that continues of a kind of Electrical Bicycle of the present utility model.
The specific embodiment
Referring to Fig. 1; a kind of under-voltage control setup that continues of Electrical Bicycle; comprise control chip P, be arranged on under-voltage protection point A, battery C on the control chip P; its improvement is: also be provided with the controlling point B that continues on the described control chip P, be in series with battery C after this continue controlling point B and described under-voltage protection point A are in parallel again.
As can be seen from Figure 1, the described controlling point B that continues connects with indicator lamp LED2, battery C; Described under-voltage protection point A connects with indicator lamp LED1, battery C.
The under-voltage value of described under-voltage protection point A is set at 41V, and the under-voltage value of the controlling point B that continues is set at 43.5V.When battery C voltage dropped to 43.5V, control chip P entered the under-voltage program that continues automatically, and battery C begins low discharging current; slowly drop to 2A by 10A; prolonged battery C voltage and reduced to the time of 41V under-voltage protection point A, the speed of a motor vehicle slowly reduces to 8～10 kilometers/hour, and mileages of continuation increases.Through repeatedly test, under-voltage mileages of continuation can reach 10～15 kilometers, is 2～3 times of existing Electrical Bicycle mileages of continuation.
Described indicator lamp LED1, LED2 are separately positioned on the instrument carrier panel, select for use light-emitting diode to make.When cell pressure reduces setting value to the setting value of the controlling point B that continues or under-voltage protection point A, constantly flicker respectively, the prompting user in time charges.
