Please consult again Fig. 1, when electronlmobil carries out the trickle charge charging, the open contact adhesive of trickle charge contactless switch and total negative contactless switch, the conducting of trickle charge loop, power supply source (not shown) charges to Vehicular charger by trickle charge charge port (not shown), and Vehicular charger charges to power brick after alternating current is converted into direct current (DC); When electronlmobil charges soon, fill soon the open contact adhesive of contactless switch and total negative contactless switch, fill soon the loop conducting, non-Vehicular charger charges to power brick by filling soon socket; When driving, the open contact adhesive of total positive contactless switch and total negative contactless switch, the discharge loop conducting, power brick is powered to current consumers such as electric machine controller, umformer DC/DC, air-conditioning and heater block PTC.
Please consult Fig. 1, Hall element is used for gathering the total current in power brick loop again; The voltage temperature acquisition module be used for to gather the voltage of each cell of power brick, and the temperature of each temperature acquisition point, i.e. the temperature of the battery cell that gathers of each described temperature sensor; The insulating monitoring module is used for gathering power brick to the insulation resistance on vehicle body ground; Electronlmobil travel or process of charging in, each acquisition module is issued battery management system BMS with the battery data that collects and is carried out management of computing, when calculating, battery management system BMS finds that there are deviation in certain data of battery and normal data, battery management system BMS will send fault alarm, and will be specific as follows:
(1) when detecting, Hall element recharges electric current (when driving in the way circuit, motor can generate electricity in the time of such as electronlmobil descending or brake, power brick is recharged, and the electric current of generating just be called recharge electric current) when excessive, battery management system BMS sends fault alarm, and the open contact of the total negative contactless switch of control and total positive contactless switch disconnects;
(2) detect discharge current in way circuit when excessive (during such as short circuit or high vehicle speeds when Hall element, discharge current can continue larger), battery management system BMS sends fault alarm, and the open contact of the total negative contactless switch of control and total positive contactless switch disconnects;
(3) when the insulating monitoring module detects power brick the insulation resistance on vehicle body ground is crossed when low (as directly being connected with car body when electric wire is aging, being equivalent to insulation resistance is zero, so just, cause the car load charged), when namely being lower than twice 200 Ω that GB requires 100 Ω/V/V, battery management system BMS sends fault alarm, and the open contact disconnection of the always negative contactless switch of control and total positive contactless switch, to guarantee safety, because if insulation resistance is excessively low, the car shell is charged will be dangerous.
(4) cross when low when SOC is lower than 20% as lotus quantity of electric charge SOC (battery management system BMS can calculate SOC according to total voltage and charging and discharging currents), battery management system BMS sends fault alarm, and Limited Current output, makes vehicle limit power to travel.
(5) when the voltage temperature acquisition module collects the battery cell voltage below level, battery management system BMS sends fault alarm, and the open contact disconnection of the always negative contactless switch of control and total positive contactless switch, causes scrapping to prevent the power brick over discharge.
(6) when the voltage temperature acquisition module collects the battery cell overtension, battery management system BMS sends fault alarm, if be in the process of filling soon this moment, then control the open contact that fills soon contactless switch and total negative contactless switch and disconnects; If be in the trickle charge process this moment, the open contact of then controlling trickle charge contactless switch and total negative contactless switch disconnects, thereby prevents the power brick blast;
(7) collect battery cell when too high or too low for temperature when the voltage temperature acquisition module, if be in the driving process this moment, then the open contact of the total negative contactless switch of battery management system BMS control and total positive contactless switch disconnects; If be in the process of filling soon this moment, then control the open contact that fills soon contactless switch and total negative contactless switch and disconnect; If be in the trickle charge process this moment, the open contact of then controlling trickle charge contactless switch and total negative contactless switch disconnects; If because the battery cell excess Temperature is relatively more dangerous, may cause the power brick blast; If the battery cell temperature is excessively low, then power brick can't regular discharge.
