Abstract

The utility model discloses an electric vehicle control system with an anti-electric shock function in water. The electric vehicle control system comprises a water-falling probe, a current voltage detecting unit, an accelerator signal detecting unit, a CPU (Central Processing Unit), a battery pack relay drive circuit, a battery pack relay, a battery pack, a driving motor controller enabled relay drive circuit, a driving motor controller and a driving motor, wherein the battery pack relay is composed of a plurality of relays; the battery pack is composed of a plurality of batteries; and the batteries are connected in series through the relays; and the CPU can control the driving motor when the electric vehicle is accelerated so as to reduce vibration of the electric vehicle. The electric vehicle control system with the anti-electric shock function in water, disclosed by the utility model, has the advantages of reducing a loop voltage, guaranteeing personal safety of a driver, processing an acceleration signal and efficiently relieving vehicle vibration phenomenon when the electric vehicle is accelerated as the relays among the batteries can be cut off in time to separate each battery when the electric vehicle falls into water.

Description

A kind of electric vehicle control system that has the electroshock-proof function that falls into water
Technical field
The utility model belongs to electric motor intelligent control field, is specifically related to a kind of electric vehicle control system that has the electroshock-proof function that falls into water.
Background technology
Battery of electric vehicle group power supply voltage is that 36V-110V does not wait, and its voltage is all greater than safety voltage, and the voltage that 36V AC/DC is above when the electric current about 1 milliampere passes through human body, can produce uncomfortable feeling such as fiber crops thorn; The electric current of 10-30 milliampere is known from experience symptoms such as producing paralysis, severe pain, spasm, blood pressure rising, expiratory dyspnea through the people, but does not have life danger usually; Electric current reaches more than 50 milliamperes, will cause ventricular fibrillation and is in peril of one's life; Electric current more than 100 milliamperes is enough to cause the people in the fatal position.
In a single day present battery-driven car falls into the water, because water is conductor, so will form a circuit loop, will damage human body, possibly threaten the life security of navigating mate even.
The utility model content
The utility model purpose: the purpose of the utility model is in order to solve the deficiency of prior art, a kind of electric vehicle control system that has the electroshock-proof function that falls into water to be provided.
Technical scheme: the described a kind of electric vehicle control system that has the electroshock-proof function that falls into water of the utility model comprises the probe that falls into water, the current/voltage detecting unit; The accelerator signal detecting unit, CPU, battery pack relay drive circuit; The battery pack relay; Battery pack, the electric machine controller that goes enables relay drive circuit, and the electric machine controller and the motor that goes go; The input end of said CPU is connected with the accelerator signal detecting unit with the probe that falls into water, current/voltage detecting unit respectively; The mouth of said CPU enables relay drive circuit with the battery pack relay drive circuit with the electric machine controller that goes respectively and is connected, and said battery pack relay drive circuit also is connected with at least one battery pack relay, and said battery pack relay also is connected with battery pack; The said electric machine controller that goes enables relay drive circuit and also is connected with the electric machine controller that goes, and the said electric machine controller that goes also is connected with the motor that goes.
Said battery-driven car comprises Electrical Bicycle and electronlmobil.
Said battery pack comprises at least two batteries, and said battery is connected in series through the battery pack relay.
Cell pressure between adjacent two said battery pack relays is not more than 12V.
Beneficial effect: the utility model can in time cut off the relay between battery when battery-driven car falls into water; Each battery is separated; Reduced loop voltage, guaranteed driver's personal safety, simultaneously ARC Acceleration Signal has been handled; The vehicle jitter phenomenon has guaranteed the traveling comfort that battery-driven car is taken when effectively having alleviated the battery-driven car acceleration.
Description of drawings
Accompanying drawing is the circuit structure block diagram of an embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Like a kind of control system of electric automobile that has the electroshock-proof function that falls into water shown in the drawings, comprise the probe that falls into water, the current/voltage detecting unit; The accelerator signal detecting unit, CPU, battery pack relay drive circuit; Five battery pack relays 1; Six battery pack that 12V storage battery 2 is formed, the electric machine controller that goes enables relay drive circuit, and the electric machine controller and the motor that goes go.
Wherein the input end of CPU is connected with the accelerator signal detecting unit with the probe that falls into water, current/voltage detecting unit respectively; The mouth of CPU enables relay drive circuit with the battery pack relay drive circuit with the electric machine controller that goes respectively and is connected; The battery pack relay drive circuit also is connected with five battery pack relays 1; The electric machine controller that goes enables relay drive circuit and also is connected with the electric machine controller that goes, and the electric machine controller that goes also is connected with the motor that goes.
Six 12V storage batterys in the battery pack are connected in series through five battery pack relays; And the voltage between adjacent two battery pack relays is 12V; Even electronlmobil is fallen in the water like this; CPU cuts off and is connected the relay in the battery, and the voltage that forms the loop is merely 12V, can not damage navigating mate; Thereby CPU controls the electric machine controller that goes through detecting accelerator signal simultaneously; Reduce to greatest extent owing to electronlmobil quickens the shake bring; Guaranteed the traveling comfort that electronlmobil is taken, the current/voltage detecting unit can be monitored the current/voltage value of electronlmobil in real time.
