Description
[technical field]
The utility model relates to elec. vehicle, relates in particular to a kind of Electrical Bicycle or battery-operated motor cycle.
[background technology]
Fast the vehicle were once fashionable for a time easily as a kind of for the gasoline motor bike.But, along with the raising of city to environmental demands, the gasoline motor bike urban consumption market of fading out gradually.Compare with the gasoline motor bike, Electrical Bicycle/battery-operated motor cycle energy utilization rate height, pollution-free, low noise, thermal radiation is little, simple to operate, maintenance is easy, be subjected to vast cities and towns customer's favor, Electrical Bicycle/battery-operated motor cycle instead of gasoline motor bike has been irreversible trend.
Electrical Bicycle and battery-operated motor cycle are propulsion source with the storage battery.In the parts and assembly of Electrical Bicycle and battery-operated motor cycle, storage battery is the weakest link.In general, the design life 3-5 of storage battery, yet, actual only the use about 1 year, in addition shorter.Great majority are not that storage battery is scrapped fully, but capacity reduces, as long as and in circuit series, have a storage battery assembly capacity to reduce, will directly influence the use of whole group storage battery, even the good part storage battery of original state, normal electric power is additional to be damaged because of obtaining.
3 or 4 12V storage battery assemblies of the general employing of existing Electrical Bicycle and battery-operated motor cycle are connected into the direct supply of 36V or 48V.Though the voltage with a plurality of 12V storage battery assembly series connection can raising direct supplys brings some benefits to circuit layout.But this have following shortcoming inevitably with the series connected mode of a plurality of 12V storage battery assemblies:
1. under series system, the vehicle performance of Electrical Bicycle and battery-operated motor cycle is limited by the state of each the 12V storage battery assembly that is connected in the power supply, and each total Chengdu of 12V storage battery may become the bottleneck of vehicle performance.The performance that capacity attenuation all can influence the normal storage battery assembly performance of other capacity that is connected in the power circuit appears in any one 12V storage battery assembly.In this case, the output voltage of direct supply and outgoing current all can be affected, and the outgoing current of direct supply is subject to the outgoing current of trouble accumulator direct supply, thereby reduce the in-use performance of car load widely.That is to say, as long as have a 12V storage battery assembly to break down whole storage battery assemblies can't be worked and cause Electrical Bicycle and battery-operated motor cycle stagnation of movement.
2. power supply dilatation difficulty.The dilatation of 36V power supply needs to increase at least joins 3 12V storage battery assemblies; The dilatation of 48V power supply needs to increase at least joins 4 12V storage battery assemblies.And the required 12V storage battery assembly of dilatation wants model identical.The user is difficult to the requirement according to the continuation of the journey mileage, increases on a small quantity and joins 12V storage battery assembly and carry out dilatation.
3.36V need special-purpose electrical part with the 48V power supply, the electrical part commonality and the interchangeability of Electrical Bicycle and battery-operated motor cycle are relatively poor.
Adopt series connected 36V or 48V direct supply, controller needs voltage drop element, the circuit structure complexity, and cost is higher.
[summary of the invention]
It is stable that the technical problems to be solved in the utility model provides a kind of power source performance, and dilatation is convenient, Electrical Bicycle/battery-operated motor cycle that the electrical part commonality is good.
It is comparatively simple that the technical matters that the utility model further will solve provides a kind of controller circuit structure, lower-cost Electrical Bicycle/battery-operated motor cycle.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of Electrical Bicycle/battery-operated motor cycle, comprise direct supply, controller and electrical motor, described direct supply comprises at least 2 12V storage battery assemblies, and described 12V storage battery assembly is connected to become the 12V direct supply with parallel way.
Above-described Electrical Bicycle/battery-operated motor cycle, described controller is the 12V controller preferably.
Above-mentioned Electrical Bicycle/battery-operated motor cycle, described 12V controller comprises single chip machine controlling circuit and switch circuit, the external 12V direct supply of described single chip machine controlling circuit and switch circuit, the control output end of single chip machine controlling circuit connects the controlled terminal of switch circuit, the output termination electrical motor of switch circuit.
Above-described Electrical Bicycle/battery-operated motor cycle, described electrical motor is the 12V electrical motor preferably.
Above-described Electrical Bicycle/battery-operated motor cycle, the interface circuit of direct supply preferably also comprise the dilatation interface.
Above-described Electrical Bicycle/battery-operated motor cycle, described electrical motor can be permanent magnet motors
The utility model has been compared following advantage with prior art:
Because direct supply adopted can a plurality of 12V storage battery assembly parallel connection connection mode, the performance that capacity attenuation can't influence the normal storage battery assembly performance of other capacity that is connected in parallel in the power circuit appears in a 12V storage battery assembly, and the capacity that can also maximize simultaneously the storage battery that performance decayed discharges.The capacity of direct supply output is that fault storage battery assembly output capacity is with normal storage battery assembly output capacity sum.Quantity as the 12V storage battery assembly of parallel connection is more, it is not too big to the influence of the in-use performance of car load that capacity attenuation appears in indivedual storage battery assemblies, more can whole storage battery assemblies can't be worked cause the situation of Electrical Bicycle stagnation of movement, guaranteed that the Electrical Bicycle power source performance is stable because of one of them 12V storage battery assembly only breaks down.
2. the power supply dilatation is convenient.The user can be as required arbitrarily increase with hobby join 12V storage battery assembly, increase the quantity of joining the storage battery assembly and do not require and limit, but arbitrary combination is joined 1 12V storage battery assembly and also can be carried out the dilatation of direct supply even only increase.And the model of the required 12V storage battery assembly of dilatation do not have special requirement yet, as long as rated voltage is identical just passable.Like this, the user can increase according to the requirement of continuation of the journey mileage fully and joins 12V storage battery assembly and carry out the direct supply dilatation.
3. the car load power supply is 12V, and the electrical part apolegamy is convenient, even can use the electrical part of automobile or motor bike, and commonality and interchangeability are good.And controller does not also need voltage drop element, can use circuit structure simple, lower-cost controller.
4. to the low user that requires of continuation of the journey mileage, direct supply can only be joined 2 groups of 12V storage battery assemblies, has both reduced integral vehicle cost, has reduced complete vehicle weight again.
