Wherein, battery bracket 101 is located on vehicle body 20, and this electrokinetic cell is located in Battery case 102.
The utility model additionally provides collision detecting device 20.As shown in Figure 7 and Figure 8, fill 20 according to the impact detection of the utility model embodiment and comprise the first crash sensor, the second crash sensor and the first resistance R1.This first crash sensor and this second crash sensor are crash sensor 104.One end of first resistance R1 is connected with the first end of this second crash sensor with this first crash sensor respectively.
Fill the working process of 20 according to the impact detection of the utility model embodiment below with reference to Fig. 1-Fig. 9 description.When vehicle (such as battery-driven car) does not collide or slight impact (this collision prevention girders caves in the inner side of vehicle) occurs, this collision prevention girders and Battery case 102 can not extrusion and collision sensors 104, and crash sensor 104 does not trigger collision warning.That is, both sides not conductings (as shown in Figure 7) of this first crash sensor and this second crash sensor, the collision alarm pin (pin 2) of battery manager 21 is low level, and the level signal of the impact detection pin (pin 2) of battery manager 21 is 24V high level.
When vehicle generation severe crash, inner side depression from this collision prevention girders to vehicle and extrude with Battery case 102, thus can extrusion and collision sensor 104, and trigger crash sensor 104 collision warning, battery management controls disconnection high-tension current.Specifically, after crash sensor 104 is squeezed, first electric-conductor 1043 contacts (as shown in Figure 8) with the second electric-conductor 1044, thus the both sides conducting of this first crash sensor and/or this second crash sensor can be made, the collision alarm pin (pin 2) of battery manager 21 is low level, and the level signal of the impact detection pin (pin 2) of battery manager 21 is low level signal.
Crash sensor 104 according to the utility model embodiment passes through in the container cavity 1042 of body 1041, arrange isolated first electric-conductor 1043 and the second electric-conductor 1044, thus the first electric-conductor 1043 contacts with the second electric-conductor 1044 when collision happens, to make the both sides conducting of this first crash sensor and/or this second crash sensor, and then battery manager 21 can be made to control to disconnect high tension loop.

Advantageously, the second end ground connection of the first crash sensor 104 and the second crash sensor 104.
As shown in Figure 9, collision detecting device 20 can also comprise the second resistance R2 and the 3rd resistance R3.One end of second resistance R2 is connected with one end of the first resistance R1.One end of 3rd resistance R3 is connected with the second end of this second crash sensor with the other end of the second resistance R2 and this first crash sensor, the other end ground connection of the 3rd resistance R3.
Battery manager 21 has the function of vehicle mounted dynamic battery (this vehicle mounted dynamic battery can be located in Battery case 102) being carried out to energy management.Specifically, when vehicle-state is normal, battery manager 21 allows this vehicle mounted dynamic battery to power.When vehicle-state is abnormal, battery manager 21 does not allow high-tension battery to power, and disconnects high tension loop.
Battery manager 21 sends collision alarm, and monitors collision sensing signal.Battery manager 21 is by controlled discharge contactless switch and the high tension loop of dividing potential drop contactless switch break-make.
Power safety box is made up of dividing potential drop contactless switch and insurance.This dividing potential drop contactless switch is controlled by battery manager 21, mainly plays disconnection high tension loop, reduces the effect of battery pack normality voltage.Insurance fuses when high tension loop electric current is excessive, plays passive protection effect.In addition, power safety box can prevent battery modules partial short-circuit.Current Hall sensor Main Function detects the real-time current in high tension loop, and signal is sent to battery manager 21.
Power safety box is arranged in battery modules inside, and connects with the battery core in battery module.Dividing potential drop contactless switch and the insurance of power safety box inside are connected in series.Be connected in series between battery module, composition power battery pack.
By adding power safety box in battery module inside, thus when being short-circuited between power battery module, fuse protection can be realized.When colliding, even if generating contactless switch disconnects, also just the loop between high-tension battery group and consumer is disconnected, the open circuit voltage of power battery pack is still very high.Increase dividing potential drop contactless switch, power battery pack can be made to divide and be broken into multiple part, the voltage of every part is all lower, thus reduces the risk that electric shock accidents occurs, vehicle being leaked electricity when colliding and probability on fire greatly reduces, making user not be vulnerable to high pressure spot and hitting.Can realize electrokinetic cell " low pressure ", when electrokinetic cell is out-of-run, dividing potential drop contactless switch disconnects, and is conducive to the storage of electrokinetic cell, transport, Assembly &Disassembly.
Dividing potential drop contactless switch can be designed to often open, and after low-voltage power supply cuts off, dividing potential drop contactless switch automatically resets.
