Abstract
The utility model relates to a system for increasing an electric automobile driving range. The system comprises a power battery pack. The power battery pack is connected with a DC-DC module. The DC-DC module is connected with an expansion power battery pack system. A plurality of expansion battery packs are arranged in the expansion power battery pack system. A battery monitoring system is arranged in the plurality of expansion battery packs. The battery monitoring system is connected with the DC-DC module through a CAN bus. The beneficial effects of the system are that, the structure is compact, the design is reasonable, the installation is convenient, the stability is high, the number of the battery packs can be changed at will, and therefore the flexibility of the system is raised; because the battery monitoring system is arranged inside the expansion battery pack module, the safety and the reliability of the system are ensured; fuel oil is not employed to provide energy and the system is green and environmentally friendly.
Description
Technical field
The utility model relates to a kind of system that increases electric automobile continual mileage.
Background technology
The scheme of existing electric automobile continual mileage, major part be all while dispatching from the factory just with distance increasing unit, distance increasing unit is arranged on vehicle always, no matter whether user uses, distance increasing unit all will take weight and space.Even if user 1 year is with once, distance increasing unit also will take weight and space the whole year, and other distance increasing unit scheme adopts fuel oil as energy source, exist and pollute, and noise is larger, less economical, for other type distance increasing unit, cost is higher, and user is difficult to accept mostly.
Utility model content
The purpose of this utility model is to provide a kind of system that increases electric automobile continual mileage, to overcome currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of system that increases electric automobile continual mileage, comprise power battery pack, described power battery pack is connected with DC-DC module, described DC-DC module is connected with and expands electrokinetic cell group system, in described expansion battery pack system, be provided with some expansion battery pack, in described some expansion battery pack, be provided with battery monitor system, described battery cell monitoring is to be connected with DC-DC module by CAN bus.
Further, described some expansion battery pack are connected in parallel mutually.
Selectable, described some expansion battery pack are connected in series mutually.
Further, described DC-DC module and power battery pack are connected in parallel
The beneficial effects of the utility model are: compact conformation, reasonable in design, easy for installation, good stability, and because the number of battery pack can arbitrarily be changed, thereby the flexibility that has improved system, owing to expanding battery module inside, battery monitor system is housed, thereby ensure the security reliability of system, and do not adopted fuel oil to provide energy, environmental protection.
Brief description of the drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the circuit block diagram one of the system of the increase electric automobile continual mileage described in the utility model embodiment;
Fig. 2 is the circuit block diagram two of the system of the increase electric automobile continual mileage described in the utility model embodiment.
In figure:
1, power battery pack; 2, DC-DC module; 3, expand battery pack system; 4, expand battery pack; 5, battery monitor system.
Embodiment
As shown in Figure 1-2, a kind of system that increases electric automobile continual mileage, comprise power battery pack 1, described power battery pack 1 is connected with DC-DC module 2, described DC-DC module 2 is connected with and expands electrokinetic cell group system 3, in described expansion battery pack system 3, be provided with some expansion battery pack 4, in described some expansion battery pack 4, be provided with battery monitor system 5, described battery monitor system 5 is connected with DC-DC module 2 by CAN bus.
Described DC-DC module 2 is connected in parallel with power battery pack 1.
As shown in Figure 1, described some expansion battery pack 4 are connected in parallel mutually.
As shown in Figure 2, another kind of feasible program is that described some expansion battery pack 4 are connected in series mutually.
When concrete enforcement, expanding the quantity of the expansion battery pack 4 in battery pack system 3 can freely select, after some expansion battery pack 4 are each other in series or parallel, be connected with DC-DC module 2, DC-DC module 2 is in parallel with power battery pack 1, for vehicle high-pressure system provides energy.Simultaneously, the battery monitor system 5 expanding in battery pack 4 is aggregated into the battery cell voltage, the temperature that expand battery pack 4 inside in DC-DC module 2, DC-DC module 2 is according to the information such as temperature, voltage of battery core, calculate applicable electric current, the module voltage that expands power battery pack 4 is transformed to applicable voltage by DC-DC module 2, in the situation that not damaging battery core, provide applicable electric energy.So that normally for high voltage power system provides energy.When actual operation, each module adopts connector to connect; Each battery module can be any battery pack that is applicable to automobile, in battery pack, can adopt any type of battery core.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
