Electric motor car high energy pocket type iron-nickel storage battery
Technical field
The utility model relates to the green storage battery, particularly electric motor car high energy pocket type iron-nickel storage battery that electric bicycle uses.
Technical background
There is the multiple battery product in present domestic electric motor car market, all can be used in the electric motor car as Ni-H cell and lithium (ion) battery and fuel cell etc.But they are used in and also have such or such deficiency on the electric bicycle: Ni-H cell high temperature self-discharge rate height, capacity descend very fast; Lithium (ion) battery quality instability, inflammable and explosive, cost is too high, and the consumer still can't accept; Being used in from the laboratory to the low-cost production on the electric bicycle as for fuel cell also to need one period long period.Lead-acid battery is that advantage is occupied the Battery Market more than 90% with low cost, but capacity attenuation is serious, the life-span is too short, contaminated environment.Therefore a kind of excellent performance of urgent need exploitation, green power supply safe and reliable, that the life-span is long, use cost is low substitute them, satisfy the growing demand in electric motor car market.
Goal of the invention
The utility model is intended to fill up the domestic technological gap that does not still have electric bicycle high energy pocket type iron-nickel storage battery, and a kind of firm in structure, the life-span is long, use cost is minimum green power supply--electric motor car high energy pocket type iron-nickel storage battery is provided.
The utility model content
Content of the present utility model: a kind of electric motor car high energy pocket type iron-nickel storage battery is characterized in that the described 12V storage battery that is made of ten battery unit bodies.Each battery unit body all has positive plate group (1), negative plate group (2) and fibre diaphragm (3) to combine, is respectively charged in the groove of storage battery pot shell (7), and bonding with battery cap (8).
The utility model content: a kind of electric motor car high energy pocket type iron-nickel storage battery is characterized in that described each battery unit body all has the positive plate group (1) of two positive plates formations and the negative plate group (2) of two negative plate formations to combine.
The utility model content: a kind of electric motor car high energy pocket type iron-nickel storage battery, it is characterized in that adopting between the described battery unit body great-leap-forward to be connected in series, the battery unit body at two ends has positive and negative pole (9,10) to be connected with outer carrying respectively.
The utility model content: a kind of electric motor car high energy pocket type iron-nickel storage battery is characterized in that having between the positive and negative pole plate of each battery unit body two-layer fibre diaphragm (3) insulation to isolate.
The utility model content: a kind of electric motor car high energy pocket type iron-nickel storage battery is characterized in that storage battery pot shell (7) and battery cap (8) adopt bonding method to solidify and sealing.
The utility model content: a kind of electric motor car high energy pocket type iron-nickel storage battery is characterized in that ten cylindrical air exhaust pipes (5) are arranged in the battery cap (8).All there is air discharge duct each blast pipe both sides, the outside dark bowl-shape safe bonnet (4) that is locked, and require to cover the air discharge duct of both sides, the top loam cake has limiting plate (6), constitutes ten independently limited pressure safety air vavles.
The utility model has the advantages that vibration resistance firm in structure, overcharging resisting overdischarge, memory-less effect, the life-span is long, use cost is minimum, environmental protection.Particularly on the bag-type battery key technology, important breakthrough is arranged, improved effectively that pocket type iron-nickel storage battery internal resistance is big, poor performance at low temperatures, active material utilization is low, the specific capacity specific power is low technical barrier.
