Fig. 7.3. An arrangement of the storage battery and the generator in the motor a compartment: 1 – the storage battery; 2 – the generator
The arrangement of the storage battery and the generator in the motor a compartment is shown on fig. 7.3.
Pressure of onboard system of an electric equipment of all cars considered in a given management is made 12 В by""Weight"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 engine start-up the starter is used. The starter switch — the component of the switch of ignition — at inclusion submits pressure on established on a relay starter. The generator is put in action from a cranked shaft of the engine through клиновой a belt. Established on a back cover of the generator the regulator serves for adjustment зарядного a current.
The storage battery consists of six elements (банок). The battery develops a current necessary for start-up of the engine of the car, work of system of ignition and illumination, and also other consumers of the electric power.
Care of the storage battery
That the battery served longer, and its capacity was maximum, from time to time it is necessary to perform following works.
Always it is necessary to contain the battery and details surrounding it in cleanliness. The battery surface should be dry, differently between separate banks there can be superficial currents of leak because of what the battery will be discharged in itself.
Electrolit level should be constantly at a ring located from the bottom party of the bulk chamber. For доливки 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. Slabozarjazhennye batteries freeze already at temperature nearby–10 °С.
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 battery removal remove a cover.
At switching-off of the storage battery from memory of the central block of a control system of the engine and a transmission, antiblocking system of brakes, of some other electrodevices, for example a radio receiver and hours, the information on taking place malfunctions is erased. After connection anew program corresponding devices. Some serially established radio receivers are supplied by a protective code. It prevents unapproved 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 a corresponding safety lock. If the radio receiver is coded, before its switching-off 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 servicing deport Hyundai.
Uncover a water-proof casing.
Switch off ignition.
Disconnect at first a cable of "weight" of the battery, then «плюсовый» a cable.
Turn away a bolt of a plate of fastening, take out the storage battery.
In the storage battery poisonous connections which should not get to household dust contain. The batteries which have served the term hand over in special points of reception for recycling.
Before installation clear plugs of the storage battery, the brass wire brush for this purpose will approach. For corrosion prevention cover plugs of the battery with special greasing.
Establish the battery, tighten a bolt of a plate of fastening by the moment 20 Н·м.
Connect «плюсовый» a 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 an 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.,
Degree check разряженности batteries
The electrolit density together with pressure measurement on plugs of the storage battery allows to draw an exact conclusion on degree заряженности batteries. For check serves ареометр which can be got in specialised shop. The more the electrolit density, the rises more the float ареометра (emerges). On a scale ареометра values are expressed in terms of density (g/sm 3).
During measurement of density of electrolit watch that on a battery surface, the body and other details from a pipette ареометра did not fall the drops of electrolit containing sulfuric acid which causes corrosion and current leaks.
At measurement of density of electrolit the electrolit temperature should be in limits 20–30 oС. The electrolit density should be measured in each element (bank) of the storage battery. After measurement of density of electrolit it is possible to establish degree разряженности batteries.
The electrolit density in all banks should be identical.
The electrolit density in completely charged storage battery makes 1,28 g/sm 3; in discharged on 25 % – 1,24 g/sm 3; discharged on 50 % – 1,20 g/sm 3.
The storage battery discharged more than on 25 % in the winter and more than on 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 pressure.
Pressure of completely charged accumulator room of the battery at engine start-up should be not less than 8 In (at electrolit temperature, so, and environment, +20 °С).
If pressure sharply falls and in elements (banks) of the battery the different density of electrolit has been revealed, it is possible to draw a conclusion on malfunction of the battery.
Never close the battery накоротко — do not connect «плюсовую» and "minus" plugs. At short circuit the battery heats up and can blow up.
The electrolit should not get to eyes, on a skin and clothes; at electrolit hit on a skin or in eyes смойте its considerable quantity of water.
Before gymnastics disconnect from the battery at first "a weight" cable, then «плюсовый» a cable.
Before gymnastics check up electrolit level, if necessary add the distilled water.
The frozen battery (the battery the electrolit in which has frozen) before gymnastics defreeze. Completely charged battery freezes at temperature–65 °С, half charged battery — at temperature–30 °С, the discharged battery — at temperature–12 °С.
Charge the battery only in well aired premise. At gymnastics of the established battery leave a car cowl opened.
At normal gymnastics зарядный the current makes approximately 10 % of capacity of the battery (i.e. the battery in capacity 50 А·ч should be charged by a current approximately 5,0). Gymnastics time can be accepted 10 ч.
Connect the positive plug of the storage battery with «плюсовым» a wire, the negative plug of the battery to "a minus" wire зарядного devices.
During gymnastics the electrolit temperature should not exceed +55 °С, if necessary interrupt gymnastics or reduce value of a current of gymnastics.
Charge the battery until in all elements of the battery plentiful liberation of gas will not begin and at the following one after another in an hour three measurements the density of electrolit and pressure will not cease to increase.
After gymnastics check up electrolit level, if necessary add the distilled water.
The engine should not work at the disconnected storage battery, differently the electric equipment system will be damaged.
Fast gymnastics 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 fast gymnastics 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 long time, are discharged in itself and can be subject сульфатации plates. If such batteries to charge быстрозарядным the device, they do not accept зарядный a current because of so-called superficial gymnastics.
Before to reject the battery, check up the following:
– Electrolit density. If in all elements it differs no more than on 0,02 g/sm 3, the battery should be charged зарядным the device;
– Under loading after gymnastics. If values do not correspond demanded, the battery is faulty;
– Electrolit density. If density in one or several banks much more low, than in the others (for example, in five banks the density makes 1,16 g/sm 3, and in one 1,08 g/sm 3), in the battery internal short circuit.
To avoid battery presenilation, it is necessary to charge the battery which is 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 operating 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 presence of superficial currents of leak, check up the onboard electric system of the car.
For check use completely charged battery.
Establish on the ampermeter (with a limit of measurement 0–5 мА and 0–5) the highest limit of measurement. Include 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 all 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 indication chains will fall to 0 in this chain it is necessary to search for a malfunction source. Possible malfunctions: корродированные or the 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 the devices not protected by safety locks — the generator, a starter, elements of system of ignition.
If at switching-off of one of not protected chains of the indication of the ampermeter will fall to 0, repair or replace a corresponding element. At current leak in a starter or ignition system always check (according to the scheme) the switch of ignition and a starter.
