Description
Technical field
The utility model relates to battery for electric automobile group installing area, especially accumulator of electric car group power distribution system.
Background technology
Existing accumulator of electric car group is installed, be substantially by a group storage battery group as propulsion source, for example using 48V100AH battery, the weight of battery pack is approximately 210kg, mileages of continuation is 100 kilometers.There is larger shortcoming in actual applications in this field engineering, is mainly that battery pack weight is heavier, can not be split, and battery pack can only be fixed charging onboard, and during charging, vehicle can't use, and causes vehicle utilization greatly to reduce.And a group storage battery group is short as the electronlmobil mileages of continuation of propulsion source, but as shorter than maximum course continuation mileage as the actual mileages of continuation that needs, the battery pack electric weight remains when a lot of and will charge in advance, can cause the waste of battery.
The utility model content:
For the deficiencies in the prior art, the technical problems to be solved in the utility model is, realizes the detachable of battery pack, to alleviate its weight, and charging at any time.
In order to realize above-mentioned technical matters, the technical scheme that the utility model provides is:
Accumulator of electric car group power distribution system, comprise some battery packs and a power supply changeover device, and power supply changeover device comprises a normally closed contact and some open contacts, and an electrode of each battery pack is electrically connected to an open contact of power supply changeover device; One end of car load electrical source of power wire harness is electrically connected to controller, and the other end is electrically connected to the normally closed contact of power supply changeover device.
Preferably, accumulator of electric car group power distribution system comprises two battery packs, power supply changeover device comprises two open contacts, and an electrode of each battery pack is electrically connected to an open contact of power supply changeover device, and another electrode of each battery pack all is electrically connected to controller.
In order to optimize the distribution of weight of vehicle complete vehicle, two battery packs are arranged in respectively the front and back end of automobile, or left and right sides.
Preferably, accumulator of electric car group power distribution system comprises three battery packs, power supply changeover device comprises three open contacts, and an electrode of each battery pack is electrically connected to an open contact of power supply changeover device, and another electrode of each battery pack all is electrically connected to controller.
In order to optimize the distribution of weight of vehicle complete vehicle, automotive front is arranged a battery pack, and a battery pack is respectively arranged in both sides, automobile back.
In the Vehicle Driving Cycle process, the contact of open contact that the switch of conv contacts with one of them battery pack, realize being electrically connected to of a battery pack and car load electrical source of power wire harness, by this battery pack, to automobile, provides power.After this battery pack electric weight exhausts, converter switch is got on the open contact contacted with another battery pack, powered to automobile by this battery pack.If three battery packs or more battery packs are set, after the electric weight that is finished second battery pack, converter switch is got to on the 3rd open contact that battery pack contacts, by that analogy.The open contact that the switch of conv only contact with a battery pack in some battery packs contacts, and all the other battery packs all can be pulled down and be charged at any time.
Compared with prior art, the technical scheme that the utility model provides can adopt lightweight low capacity battery pack to take the mode of relay and provide power as electronlmobil, make electronlmobil can not be subject to the restriction in charging duration and place, greatly improved the Occupation coefficient of vehicle, and improved the course continuation mileage of electronlmobil on general effect.
For example, formerly with the 48V100AH storage battery, now be improved to two groups of 50AH storage batterys or three groups of 40AH storage batterys, the weight of so single group storage battery can be controlled to an adult and takes off and be transported to more easily upstairs or charged in other places from car, and traditional single large-capacity battery group can only be fixed charging onboard.This accumulator of electric car group power distribution system also has following technique effect: 1, and as actual, need mileages of continuation shorter, available one group or two group storage batteries are installed and are travelled onboard, and all the other battery packs charge at home or are stand-by.2, the mileage of use as actual as the customer is less than half of two groups or three Battery packs, can select one group or two group storage batteries, can buy less a group storage battery, reduces and purchases the car cost.3, the charger cost reduces greatly, and for example: the vehicle-mounted charger price of 48V/100AH storage battery is between 1200 yuan-1400 yuan, and 50AH bat.chgr. price can be saved the charger purchase cost generally in 300 yuan so greatly.
