The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
Like fig. 1 to fig. 5, the utility model relates to a remove storage battery charging system's last lower electricity and control system, including power battery, high voltage distribution cabinet, machine and energy storage energy management system charge, power battery and high voltage distribution cabinet correspond and link to each other with energy storage energy management system, and power battery all corresponds with the machine that charges and links to each other with high voltage distribution cabinet.
The power battery selects a 105AH battery cell. The power of the high-voltage distribution cabinet is 360 KW.
The mobile charging vehicle consists of an energy system (drive), an auxiliary system and an electric drive system-level charging system. Apart from the charging system, this vehicle is not clearly distinguished from other pure electric vehicles. This car has added a set of charging system on pure electric vehicle's basis, has constituted the removal storage battery car, and mobilizable electric pile that fills promptly charges for arbitrary pure electric vehicle emergency at any time and any place. The whole vehicle system block diagram is shown in fig. 2 (note: power battery (drive): referring to power battery for driving the vehicle itself, power battery (energy storage): referring to power battery for charging other vehicles and the vehicle itself).
The utility model discloses well power battery's high-voltage electricity is to high voltage distribution cabinet, and high voltage distribution cabinet distributes the high-voltage electricity to the machine that charges according to particular case, and the machine that charges realizes charging for other vehicles or this car drive battery.
Low-voltage power-on and power-off process and control logic
The low-voltage power of the energy storage Battery Management System (BMS) and the high-voltage power distribution cabinet uses normal electricity, and the low-voltage power of the charger is controlled by a rocker switch on the instrument desk. When the charger is needed to be used for charging, a low-voltage knife switch of the whole vehicle is turned on, the BMS starts to communicate when being electrified, the rocker switch on the instrument desk is pressed at the moment, the charger starts to communicate when being electrified, and after the communication is completed, the energy storage battery is not charged and has no fault, and a corresponding high-voltage electrifying process is executed. The low-voltage power supply is powered down, and only the rocker switch is turned off and then the low-voltage knife switch is turned off.
The reason why the BMS and the high-voltage power distribution cabinet use the constant power is that the BMS of the energy storage battery is communicated with the whole vehicle in real time, so that the whole vehicle controller can master the health condition of the energy storage battery, and fault information, voltage, SOC, monomer information and the like of the energy storage battery are displayed on an instrument, so that a driver can master the state of the battery in real time.
High-voltage electrifying process: the BMS self-checking succeeds, a vehicle-mounted charging machine gun inserting message is received (a charging gun of a charging machine is connected to a charged vehicle), a discharging relay in the high-voltage power distribution cabinet does not have an adhesion fault, the discharging relay is sequentially attracted, and high-voltage electrification is completed (as shown in fig. 4).
High-voltage power-off process: the charger does not have a gun insertion signal, and the vehicle-mounted charger does not need to demand current. The BMS cuts off the discharge loop to complete the high voltage reduction. When the vehicle-mounted charger fails, the BMS generates a BMS to forcibly cut off the high voltage, the charger at least reduces the current to 0A within 10s, if the current is still greater than 0A after 10s, the BMS reports a forced cut-off instruction to tell the charger, and the high voltage is automatically cut off after 1 s. As shown in fig. 5.
The low-voltage battery power shortage prevention control logic: because the low-voltage electricity used by the charging system is a low-voltage small battery of the whole vehicle, the energy storage battery BMS and the vehicle-mounted charger use the low-voltage small battery for a long time. When the charging system works, the whole vehicle driving system has no high voltage, and the low-voltage small battery cannot be charged. So energy storage battery BMS detects low pressure storage battery voltage, and when low pressure little storage battery voltage was crossed lowly, energy storage battery BMS disconnection discharge circuit sent low pressure little storage battery insufficient voltage trouble to the instrument simultaneously, reminds the driver to go up whole car high pressure, charges for the little storage battery of low pressure.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
