Traction Batteries for EV and HEV Applications

Battery Requirements for Typical Traction Applications

Traction applications have traditionally been jobs for Lead Acid batteries but the limitations of Lead Acid batteries, together with the high cost of alternatives, have in turn limited the range of potential battery powered traction applications. A typical family car would need a battery capacity of about 40 KWh to provide a one way range of 200 miles and a 40 KWh Lead Acid battery weighs 1.5 tons.


The situation is changing however as new battery chemistries and supporting technologies have brought with them new technical and economic benefits making battery power viable for traction applications that were previously uneconomic or impractical. In particular, the use of light weight Nickel Metal Hydride and Lithium batteries instead of the heavy and bulky Lead Acid batteries has made practical electric vehicles and hybrid electric vehicles possible for the first time.


Features:

◆ Using high quality alloy as grid material, creep-resistant, corrosion preventive, excellent conductivity, less gassing and low water loss rate;

◆ Long life active ingredient formula, and a strong ability to resist deep charging and discharging;

◆ Positive and negative, using paste structure, high specific energy and high current discharge performance;

◆ Using special superfine fiber of small aperture AGM partition and tight assembly process to avoid short circuit fault;

◆ The battery case is made of reinforced ABS plastic, sealed up with modified epoxy resin sealant, corrosion preventive and no acid leakage;

◆ The electrolyte is made of high purity sulfuric acid and special additives, to ensure maximum performance of electrode and suppress short circuit and self discharge;

◆ Normal use without acid replenishment or water replenishing, free maintained; if influenced by working conditions that losing a lot of water, you can add distilled water to ensure the normal performance of the electric property;

◆ The features of gel battery: advanced sealing structure, no leakage, no case bulging, no electrolyte concentration stratification, strong charge acceptance ability, water loss less, strong ability of resisting  to over charge and discharge capacity, strong ability of charge retention.
