Description
Technical field
Control of Electric Vehicles field is the utility model is related to, more particularly to it is a kind of electronic equipped with power supply optimization management system
Automobile.
Background technology
Electric automobile refers to using vehicle power supply as power, drives wheels travel with motor, meets road traffic, security legislation
The vehicle of requirements, there are problems with for existing electric automobile:When electrical equipment overload or insufficient battery electric quantity, electricity
Voltage increase in the group of pond, internal resistance increase, so that cause battery pack output voltage to decline by a big margin, it is larger to battery damage.
The content of the invention
The technical problems to be solved in the utility model is：There are problems with for existing electric automobile:When electrical equipment is overloaded
Or during battery electric quantity deficiency, voltage increase in battery pack, internal resistance increase, so as to cause battery pack output voltage fall
It is larger, it is larger to battery damage.
Technical solution provided by the utility model is：Electric automobile equipped with power supply optimization management system, including battery pack,
Power supply unit, motor control driving unit, entire car controller and vehicle-mounted electrical equipment, battery pack are connected with power supply unit, distribution
Unit is connected with motor control driving unit, entire car controller, further includes battery voltage detection unit, current sensor and can
Control switch element；Battery voltage detection unit is used to detect battery pack output voltage, current sensor be installed on battery pack with
It is used to detect battery pack output current between power supply unit, battery voltage detection unit is all connected with vehicle control with current sensor
Device processed, entire car controller are connected with switch element control terminal, and one end of switch element actuating station is connected with power supply unit, the other end
It is connected with vehicle-mounted electrical equipment.
Further, switch element is relay or electronic power switch device.
Compared with prior art, the beneficial effects of the utility model are：When the load, voltage detection unit detection battery pack
Voltage, when voltage fall is too big, information of voltage is fed back to entire car controller by voltage detection unit, and entire car controller breaks
Drive to carry power supply for electrical equipment, to protect battery pack, on the other hand by the detection of electric current, calculate the electricity of battery pack,
When not enough power supply, the supply line of vehicle-mounted electrical equipment is automatically cut off.
Brief description of the drawings
The structure diagram of Fig. 1 the utility model.
Embodiment
Specific embodiment of the present utility model is illustrated with reference to attached drawing.
Embodiment 1 is equipped with the electric automobile of power supply optimization management system, including battery pack, power supply unit, motor control drive
Moving cell, entire car controller and vehicle-mounted electrical equipment, battery pack are connected with power supply unit, and power supply unit and motor control driving are single
Member, entire car controller are connected, and further include battery voltage detection unit, current sensor and controllable switch unit；Battery pack electricity
Pressure detection unit is used to detect battery pack output voltage, and current sensor, which is installed between battery pack and power supply unit, to be used to detect
Battery pack output current, battery voltage detection unit are all connected with entire car controller with current sensor, and entire car controller is with opening
The connection of unit control terminal is closed, one end of switch element actuating station is connected with power supply unit, and the other end is connected with vehicle-mounted electrical equipment.
Preferably, switch element is relay or electronic power switch device.
Operation principle：Battery voltage detection unit detects battery voltage, and voltage signal is transferred to entire car controller,
Entire car controller judges whether voltage is too low, if too low, automatically cuts off the supply line of vehicle-mounted electrical equipment.Do not have in voltage
When too low, current signal is simultaneously transmitted to entire car controller by current sensor detection supply current, and entire car controller is believed according to voltage
Number and current signal calculate battery electric quantity residual value, when surplus it is low cross setting value when, automatically cut off the confession of vehicle-mounted electrical equipment
Electric line.
