Electric Vehicle Lead-Acid Battery

CHARACTERISTIC  

 

 

1.Large capacity

Adopting patented structure design, found the maximum effective of the battery. The 2Hr capacity is 5% -10% higher than similar products.

 

2.Excellent High current discharge performance

The grid adopts the latest structure of thin horizontal ribs and vertical ribs, which greatly reduces the ohm resistance of the battery. When the large current

discharges, the internal electrochemical reaction is uniform, the voltage drop less, and the recovery performance good after deep discharge.

 

3.Better grid corrosion resistance

Unique patented alloy material, make grid has superior corrosion resistance and creep resistance;

 

4.High utilization of active substances

The patented refine the tetrabasic lead sulphate particles produced in the paste and curing, which improves the utilization of active materials and greatly

improves the output of the battery;

 

5.Minimal water losses

Increase the amount of liquid added to the battery to solve the problem of dehydration and battery expansion at the end of the battery life;

 

 

 

 

 

6.Low self-discharge rate

A certain amount of negative electrode additive is added to the negative electrode active material by a special process method, which not only has the effect

of overcoming self-discharge, but also reduce the power consumption by 79% at the time of initial charging.

 

7.Low temperature performance

Highly active conductive materials and low-temperature expansion are added to the plates, which is superior low-temperature charge and discharge

capabilities, which prevents the battery's continuous mileage from declining in winter.

 

8.Safe and reliable

Each valve of the battery box is independently designed, with automatic anti-early drying and detachable safety valve. The valve not only has the function of

checking the fluid replacement of the common battery, but also has the sealing function of the one-way exhaust of the sealed battery, making the battery

Less water loss during charge and discharge process, higher sealing efficiency, use of high capacity, no liquid leakage, high gas recombination function on

electric bicycles, and easy removal of safety in the event of maintenance Valve maintenance.

 

9.Long service life

Under standard conditions DOD80% can perform 600-800 cycles, and 1 time charges is able to travel 40~60Km.

Safe Use Precautions

Battery Use

1.Batteries are delivered fully charged. During the storage before installation, the capacity of battery will decrease in different degrees. If the storage time is longer, battery should be recharged. If the storage time is less than 6 months, batteries should be recharged in constant voltage limit current 2.27V/Cell, the maximum current should be less than 0.25 C A, charging time 48~72h.

2.Batteries could be in standby use and cycle use. Please charge the battery in constant voltage and limit current, the maximum current : 0.1C10～0.25 C10 A, battery standby use: 25℃ 2V series: 2.25V/Cell, 6V or 12V series: 2.27V/Cell; battery cycle use: 25℃, 2V series: 2.35V/Cell, 6V or 12V series: 2.40V/Cell.

3.If the ambient temperature is too high or too low, in case the ambient temperature exceeds 20℃～30℃, then the charging voltage should be adjusted, in case of higher temperature, decreases the charging voltage, and in lower temperature increases the charging voltage, the correction factor : 4mV/℃. Besides, that ambient temperature of battery is too high or too low will also influence the capacity and the service life.

4.Battery should be recharged after the installation or after the discharging, charging the battery in constant voltage limit current mode, charging voltage: 25℃ 2.35V/Cell, the maximum current: 0.1C10～0.25C10 A, if discharging in 100% capacity, the charging time is about 24h-27h, if the charging current decreases to a very low current, and retain for 3h almost invariant or the charging electric quantity is 1.15 times of the discharging electric quantity, then consider the battery have been fully charged.

5.Battery equalization charging: while the float voltage of the certain battery or some of the batteries is under 2.2V/Cell, then the whole pack of batteries should be equalization recharged, 25℃ 2.35V/Cell, the maximum current: 0.1C10～0.15 C10 A, time: 8h～12h.

Requirements of Installation and Use

1.Generally, battery are used in series connection, if batteries must be used in parallel connection, then the parallels should not be over two branches.

2.Batteries can work in an ambient temperature of -25℃～45℃. The proper using temperature is 15℃～30℃, the battery room should have necessary ventilation.

3.Batteries should be away from source of heat and spark, the security distance should be longer than 1 meter. Batteries should be stored away from direct sunlight, other rays, organic solvent gases and corrosive gases. To improve shockproof capability, the battery rack should be reinforced with foundation bolts.

4.Batteries are delivered fully charged, so during the transportation and installation, batteries should be prevented from short circuit, be careful of the short circuit caused by batteries and metal parts of battery metal shelf or metal box touches.

5.When installing the battery wires, the operator should use insulating tools and wear insulating gloves, also remove personal metal articles like watch, bracelets and so on.

6.The operator should screw the bolt tightly during the connection, the proper torque should be 5～7N.M in case of battery overheating or battery striking fire caused by loose connection.

7.Batteries of different models or different capacity cannot be mixed in use. When installing terminal connecting pieces, operators should carefully inspect if the polarity connecting is correct. The positive pole of battery connects with the positive pole of charging device, the negative pole of battery connects with the negative pole of charging device, be careful not to reverse the polarity.

Requirements of Battery Working Maintenance

1.During the battery working, the operator should take complete working records including battery voltage, current, ambient temperature and other relevant data and working time.

2.Operators should inspect the fastening condition of connecting terminals such as battery overheating or striking fire caused by the connecting strip smudge or loose connecting.

3.Inspecting the total float charging voltage, the operator should use voltmeter to measure the measurement number of battery positive and negative output end voltage is consistent with the indicating float charge voltage, and conforms to the required number of standard float charge voltage under the current temperature.

4.During the battery working, if battery voltage is abnormal, appearance has damage like battery container and cover has flaw or deformation), battery electrolyte leaks, battery temperature is normal, the operator should find the failure cause in time.

5.The appearance of battery should be cleared by clean water, organic solvent is not allowed. Be sure that battery use has a dry, clean, ventilated environment.

Notes for Battery Use

1.Don’t separate or transform the battery.

2.Don’t throw the battery into the water or the fire.

3.Please wear insulating gloves when connecting the battery packs.

4.Don’t install, use or store batteries in which children can touch.

5.Don’t use different brand, different capacity, different voltage and different degree of old and new batteries in series connection.

6.There is acid inside batteries, if battery is damaged by machine and acid splash the skin, clothes and even eyes, please wash with plenty of water or seek medical treatment immediately.
