Battery maintenance

If the battery is really out of power, don't be impatient, and don't continue to ignite again. This will make the battery that has insufficient power consume the last remaining power, once, twice, three times...there is no movement. We can settle down and use the following methods to solve it. ① Wiring If your car is equipped with a wiring, or you can borrow a wiring, you can borrow the battery of another car to ignite your car, but this method is no way, and the average car owner will not Bring your own wiring, and the operation process may also have psychological obstacles and certain dangers for friends who do not understand electrical appliances or timid ladies.　　 Although it is rarely used, it’s okay to know about it, at least you can help yourself calmly when you really need it. If you choose to use the method of wire bonding, you must pay attention to: the positive pole is connected to the positive pole; the negative pole is connected to the negative pole. Don't get the wrong direction! Otherwise, the battery may be burned out. If the electrodes are connected reversely and the battery emits white smoke or a burnt smell, then the battery can only be replaced. Another possibility is that the very low temperature in the northern winter may freeze the battery. If this is the case, you can't use the wire to save yourself. Let's demonstrate the operation process of wiring. To emphasize again: 1. Before connecting the wire to the power supply vehicle, the engine must be turned off; 2. After connecting the wire to the power supply vehicle, be careful not to let the positive and negative poles of the wire contact, which is very short-circuited. Danger. 3. When removing the wiring, remove the negative pole first, and then remove the positive pole. Under normal circumstances, only a car whose battery is losing electricity can be ignited smoothly after going through the above steps. If the car with no electricity still cannot start, then don't panic. This is because the battery of the car with no electricity has too little residual electricity, and the electricity of the powered vehicle is not enough to start. This is also a normal phenomenon. At this time, we can charge the dead car for a while (powered car can accelerate the charging speed by hitting the accelerator). If your battery is normal, it should start smoothly in 10-15 minutes.　　 If there are no tools around us, the easiest way is to use a cart to help the ignition. However, the cart requires several conditions. First, it is necessary to ensure that there is some remaining battery in the battery. If the battery is completely consumed, the cart will not help. Second, the cart method is only for manual transmission models and automatic transmission. The vehicle cannot be started by a cart, nor can it be towed with a tow rope. It can only be towed by a wire or a flatbed rescue vehicle to a 4S shop for repair.　　 The principle of 'pushing' the car is to use human power to push the car, and this kinetic energy reaction cylinder piston is forced to compress the gas in the cylinder and burn it. Before pushing the cart, we'd better find a driver who is skilled in the operation of clutches and gears to be responsible for the ignition, and find a few people behind the cart. Before pushing the car, the driver needs to turn the key to the energized position (ON), and then put the gear, when the car is pushed up a little speed, immediately raise the clutch, if the engine starts and can idling normally, it is OK . After the ignition is successful, do not turn off the flame and keep the idle speed for a period of time to charge the battery; or you can simply drive on the road for a lap, so that the charging effect will be better.　　 There is a detail to pay attention to, that is, the driver in front of the vehicle must enter the second or higher gear after the vehicle moves forward, otherwise it is likely to 'frustrate the car' because the transmission ratio of the first gear is generally very large. Of course, the car can be started smoothly when the cart is in 1st gear, but in this way, the car will suddenly slow down and then start instantly, which can easily cause the person behind the cart to hit the rear of the car and cause injury. It would be much more convenient if there were tow ropes and other rescue vehicles.
