My electric car just full of electric ride also ten miles, three days after I ride, just out there did not show the undervoltage, and carefully recalled that the three days did not close the door lock ... and then fully charged the total feeling did not ride more Before the road, no electricity. Help master, I this situation is not the battery is broken? More
Bad is not bad, but the storage capacity dropped, if the electricity is not enough to change the new one
You have a lot of reasons for this situation, the circuit will be self-discharge short circuit, the battery needs to be tested to know whether the damage
The thick black line is the negative line of the battery. Thick red line is the battery of the positive line, fine red line is the lock line! According to you, you may be wrong line, that is to say you put the fine red line and thick red line directly connected to the battery output on the positive line and not through the lock line. The correct way is to find the lock line, the two positive and negative lines directly connected to the lock. Carefully check, the body to the controller line whether there are other positive lines are controlled by the lock. Five lines of the spin, there are two control the speed of the button line, then do not control it. The other three is the rotation of the positive and negative and signal lines, according to the color can be connected. The general body into the controller line, spin and the speed line is separate, you can in the original controller line to determine the spin line color.
