Abstract
The utility model discloses a novel temperature protection electric vehicle controller, including main control unit, the temperature circuit is gathered to inside being equipped with of main control unit, collection temperature circuit include battery temperature sense terminal, filter capacitance, pull -up resistance, the thermistor of singlechip, its characterized in that: filter capacitance's the one end of one end, pull -up resistance and linking to each other of thermistor one end, filter capacitance's one end and thermistor's the public contact of one end of one end, pull -up resistance connect the battery temperature sense terminal of singlechip. Its advantage is: can monitor the inside temperature of controller, when reaching temperature protection value, the controller can reduce the cut -off current, and the speed of controller also can reduce this moment to reducing calorific capacity, having avoided using because of exceeding the quata the controller that leads to the fact to damage, the temperature of working as the controller continues to rise, and the controller can keep the cut -off current a minimum, and in order to guarantee that the controller can continue to use, after the temperature reduction of controller, the controller can recover original state.
Description
Technical field
The utility model relates to a kind of controller for electric vehicle, especially a kind of New temperature protection controller for electric vehicle.
Background technology
Electric motor car is as a kind of walking-replacing tool of practicality, and development in recent years is rapid, and electric motor car cause will have significant progress space.Controller, as one of the critical piece of electric motor car, it is mainly used to control other electron device of the startup of electric vehicle motor, operation, advance and retreat, speed, stopping and electric motor car, and it similarly is heart and the brain of electric motor car, maintains the basic running in electric motor car.Along with the development of electric locomotive application, require more and more higher to controlling functions, more and more diversification.Controller for electric vehicle generally must possess three zones; one is that speed regulates; two is excess current controls; three is under-voltage protections, specifically comprises following functions: overspeed-resisting function, under-voltage protection function, cruise function, assist function, automatically identification phase bit function, rotation-clogging protection function, short-circuit protection function, stepping formula driving functions, flexible EABS brake function, reverse charge function, zero start function, low noise controlling functions, short-circuit protection function, overload protection function.
Controller is as the topmost critical component of electric bicycle, and its Performance and quality is directly connected to the Performance and quality of electric bicycle, is also related to the direct personal safety of consumer, is therefore even more important for the Performance and quality of controller producer.The design level of controller, mainly refers to general structure design, the layout of power switch circuit, the distribution etc. of various periphery electronic devices and components is all related to the quality of controller.
Controller is in the market all based on a kind of control mode substantially.Controller operationally, if load is very large, continuous firing is near cut-off current, although the shell of controller has certain thermolysis, but thermal value is now far longer than heat dissipation capacity, temperature still can continue to rise, when the temperature of controller is too high, the easy Yin Gaowen of components and parts of the inside and losing efficacy, so product failure rate in the market remains high.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art, provides a kind of New temperature to protect controller for electric vehicle.This controller is by increasing the function of temperature protection, even if controller continuous firing is near cut-off current, when temperature continues to rise, there is the circuit of collecting temperature controller inside, the resistance of thermistor can change along with the change of temperature, the voltage that single-chip microcomputer collects also can change thereupon, thus the temperature of controller inside can be monitored, when reaching temperature protection value, controller can reduce cut-off current, the speed of this Time Controller also can reduce, to reduce thermal value, avoid the controller caused because exceeding the quata use to damage, when the temperature of controller continues to rise, controller can remain on a minimum cut-off current, to ensure that controller can continue to use, after the temperature of controller reduces, controller can return to original state.
The technical solution of the utility model is: a kind of New temperature protection controller for electric vehicle, comprise master controller, master controller inside is provided with collecting temperature circuit, described collecting temperature circuit comprises the battery temperature test side of single-chip microcomputer, filter capacitor, pull-up resistor, thermistor, it is characterized in that: one end of described filter capacitor, one end of pull-up resistor are connected with thermistor one end, the common junction of one end of one end of described filter capacitor, one end of pull-up resistor and thermistor connects the battery temperature test side of single-chip microcomputer; The other end ground connection of described filter capacitor, another termination 5V of pull-up resistor, the other end ground connection of thermistor.
The beneficial effects of the utility model are: owing to adopting technique scheme; the temperature of controller inside can be monitored; when reaching temperature protection value; controller can reduce cut-off current; the speed of this Time Controller also can reduce; to reduce thermal value; avoid the controller caused because exceeding the quata use to damage; when the temperature of controller continues to rise; controller can remain on a minimum cut-off current; to ensure that controller can continue to use, after the temperature of controller reduces, controller can return to original state.This function can reduce the damaged condition that controller causes because of overheated to greatest extent.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is circuit diagram of the present utility model.
In figure, C20 is filter capacitor, and R51 is pull-up resistor, and RT1 is thermistor, and TEMP is the battery temperature test side of single-chip microcomputer.
Embodiment
With reference in Fig. 1, the utility model comprises master controller, master controller inside is provided with collecting temperature circuit, described collecting temperature circuit comprises the battery temperature test side of single-chip microcomputer, filter capacitor, pull-up resistor, thermistor, one end of described filter capacitor, one end of pull-up resistor are connected with thermistor one end, and the common junction of one end of one end of described filter capacitor, one end of pull-up resistor and thermistor connects the battery temperature test side of single-chip microcomputer; The other end ground connection of described filter capacitor, another termination 5V of pull-up resistor, the other end ground connection of thermistor.When the temperature variation in the external world, the resistance of pull-up resistor can change thereupon, and the voltage of this tie point of TEMP also can change, and single-chip microcomputer, according to different voltage, can judge now extraneous temperature.
Temperature protection controller for electric vehicle of the present utility model is not limited to above-mentioned embodiment, and obviously, above-mentioned embodiment is only for clearly demonstrating the utility model example.It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, change or the motion of other form can also be made on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to spirit institute's apparent change of extending out of the present utility model and change and are still among protection domain of the present utility model.
