Fig. 7.3. An arrangement of the storage battery and the generator in the motor a compartment: 1– storage battery; 2–generator
The arrangement of the storage battery and the generator in the motor a compartment is shown on
Tension of onboard system of electric equipment of all cars considered in this management makes 12 Century. "Mass" of a body is connected to the "minus" plug of the storage battery. The battery is in a motor compartment or under a back seat (models with the conditioner, and also some diesel updatings).
For start-up of the engine the starter is used. The starter switch — the component of the switch of ignition — at inclusion submits tension on the relay established on a starter. The generator is put in action from a cranked shaft of the engine through maple a belt. Established on a back cover of the generator the regulator serves for adjustment of a charging current.
The storage battery consists of six elements (banok). The battery develops a current necessary for start-up of the engine of the car, work of system of ignition and lighting, and also other consumers of the electric power.
Care of the storage battery
That the battery served more long, and its capacity was maximum, from time to time it is necessary to perform the following works.
Always it is necessary to keep the battery and details surrounding it clean. The surface of the battery should be dry, differently between separate banks there can be superficial currents of leak because of what the battery will be discharged in itself.
Level of electrolit should be constantly at a ring located from the bottom party of the bulk chamber. For a dolivka it is necessary to use the distilled water.
In cold weather do not leave the battery in not charged condition as it (is more exact, the electrolit in it) will freeze. Slabozaryazhennye batteries freeze already at temperature about-10 °C.
Removal and installation of the storage battery
The battery is in a motor compartment under a black plastic cover of a water-proof casing. Before removal of the battery remove a cover.
At shutdown of the storage battery from memory of the central block of a control system of the engine and a transmission, anti-blocking system of brakes, some other electrodevices, for example a radio receiver and hours, information on taking place malfunctions is erased. After connection anew program the corresponding devices. Some serially established radio receivers are supplied with a protective code. It prevents unauthorized use of a radio receiver if its food was disconnected. A food of a radio receiver and hours is disconnected, if the storage battery, for example, is disconnected, the receiver acts in film or fuses the corresponding safety lock. If the radio receiver is coded, before its shutdown be convinced that to you the protective code is known. If the code is not known, to include a radio receiver it is possible only at Hyundai service station.
Uncover a water-proof casing.
Switch off ignition.
Disconnect at first a cable of "weight" of the battery, then a "plusovy" cable.
Unscrew a bolt of a plate of fastening, take out the storage battery.
The storage battery contains poisonous connections which should not get to household garbage. The batteries which have served the term hand over in special points of reception for utilization.
Before installation clear plugs of the storage battery, the brass wire brush for this purpose will approach. For prevention of corrosion cover battery plugs with special greasing.
Establish the battery, tighten a bolt of a plate of fastening the moment of 20 N · m.
Connect a "plusovy" cable to the positive plug of the storage battery, then a weight cable to the negative plug.
If it is required, enter a radio receiver code.
Incorrectly connected battery can become the reason of serious damages of the generator and all system of electric equipment.
Check of a technical condition of the storage battery
There are some ways of check of the storage battery, depending on it different measuring devices are used.,
Check of degree of a razryazhennost of the battery
The electrolit density together with tension measurement on plugs of the storage battery allows to draw an exact conclusion on degree of a zaryazhennost of the battery. For check the areometer which can be got in specialized shop serves. The enough of electrolit, the rises more the areometer float (emerges). On a scale of the areometer of value are expressed in terms of density (g/cm
During measurement of density of electrolit watch that on a battery surface, the body and other details from a pipette of the areometer did not fall the drops of electrolit containing sulfuric acid which causes corrosion and leakages of a current.
At measurement of density of electrolit the temperature of electrolit should be in limits of 20-30 oС. The density of electrolit should be measured in each element (bank) of the storage battery. After measurement of density of electrolit it is possible to establish degree of a razryazhennost of the battery.
The electrolit density in all banks should be identical.
The electrolit density in completely charged storage battery makes 1,28 g/cm
; in discharged for 25 % – 1,24 g/cm
; discharged for 50 % – 1,20 g/cm
The storage battery discharged more than for 25 % in the winter and more than for 50 % in the summer, remove from the car and recharge.
Battery check under loading
Connect the voltmeter to battery plugs.
Start up the engine and fix tension.
Tension of completely charged battery room of the battery at start-up of the engine should be not less than 8 In (at electrolit temperature, so, and environment, +20 °C).
If tension sharply falls and in elements (banks) of the battery the different density of electrolit was revealed, it is possible to draw a conclusion on malfunction of the battery.
Never close the battery накоротко — do not connect "plusovy" and "minus" plugs. At short circuit the battery heats up and can blow up.
The electrolit should not get to eyes, on skin and clothes; at electrolit hit on skin or in eyes wash away it a large amount of water.
Before a charging disconnect from the battery at first a "weight" cable, then a "plusovy" cable.
Before a charging check electrolit level, if necessary add the distilled water.
The frozen battery (the battery, electrolit in which froze) before a charging defreeze. Completely charged battery freezes at temperature of-65 °C, half charged battery — at temperature of-30 °C, the discharged battery — at temperature of-12 °C.
Charge the battery only in well aired room. At a charging of the established battery leave a car cowl open.
At a normal charging the charging current makes about 10 % of capacity of the battery (i.e. the battery in capacity 50 And · should be charged by a current about 5,0 h And). Time of a charging it is possible to accept 10 h.
Connect the positive plug of the storage battery to a "plusovy" wire, the negative plug of the battery with a "minus" wire of the charger.
During a charging the temperature of electrolit should not exceed +55 °C, if necessary interrupt a charging or reduce value of a current of a charging.
Charge the battery until in all elements of the battery plentiful liberation of gas will not begin and at three measurements following one after another in an hour the density of electrolit and tension will not cease to increase.
After a charging check electrolit level, if necessary add the distilled water.
The engine should not work at the disconnected storage battery, differently the system of electric equipment will be damaged.
Fast charging of the storage battery and engine start-up at the discharged storage battery. Charge the battery or start up the engine at the discharged battery by means of the device of a fast charging only in extreme cases as the battery is thus treated to action of a current of very high force. Long stored batteries cannot be charged this device. Observe instructions on battery storage.
Storage of the storage battery
Batteries which did not use a long time, are discharged in itself and sulfatatsiya of plates can be subject. If such batteries to charge the fast-charger, they do not accept a charging current because of a so-called superficial charging.
Before rejecting the battery, check the following:
– electrolit density. If in all elements it differs no more than on 0,02 g/cm
, the battery should be charged the charger;
– under loading after a charging. If values do not correspond demanded, the battery is faulty;
– electrolit density. If the density in one or several banks is much lower, than in the others (for example, in five banks density makes 1,16 g/cm
, and in one 1,08 g/cm
), in the battery internal short circuit.
To avoid battery presenilation, it is necessary to charge the battery being stored, each 3 months.
Self-discharge of the storage battery
Depending on car updating to process of a normal self-discharge of the battery consumption of energy of constantly acting consumers of energy is added. Therefore the battery on the car placed in storage, should be charged time in 1,5 months. If there is a suspicion on existence of superficial currents of leak, check the onboard power supply network of the car.
For check use completely charged battery.
Establish on the ampermeter (with a limit of measurement 0–5 мА and 0–5 And) the highest limit of measurement. Turn on the ampermeter between the negative plug of the battery and a "weight" cable. A wire from a positive conclusion of the ampermeter connect to the positive plug of the battery, a wire from a negative conclusion of the ampermeter — to the negative plug of the battery.
Switch off everything consumers of the electric power, close doors and a luggage carrier, switch off a plafond of illumination of a motor compartment.
Switch a limit of measurement of the ampermeter towards reduction until there will be any indications (admissible value makes 1–3 мА). Taking out one after another safety locks from the block of safety locks, disconnect consistently all electric chains. If at disconnection of one of chains of the indication will fall to 0, in this chain it is necessary to look for a malfunction source. Possible malfunctions: the korrodirovanny or polluted contacts of the contact sockets, the ground wires, internal short circuit in electric equipment elements.
If in the chains of malfunction protected by safety locks it is not revealed, it is necessary to disconnect wires from unprotected by safety locks of devices — the generator, a starter, elements of system of ignition.
If at shutdown of one of unprotected chains of the indication of the ampermeter will fall to 0, repair or replace the corresponding element. At leakage of a current in a starter or ignition system always check (according to the scheme) the switch of ignition and a starter.
