KR20000063383A - External non-charging dual power electric vehicle - Google Patents

Abstract

PURPOSE: An electric vehicle having a dual power source is provided to travel the vehicle for a long time without exterior charging and prevent the over-discharging of a battery and the lowering of the output power when the vehicle travels a mountain. CONSTITUTION: Two batteries are alternately supply the power source by adding a battery which is an electric power source of an electric vehicle. The rotational force generated in a main power motor rotated by a battery power and a rear wheel of a vehicle is connected by a charging generator and a power transmitting device such as a belt. A DC power source generated by the rotational force is charged in a preliminary battery automatically separated from a main power supplying circuit. If the battery supplying an electric power is discharged, the power source supplying circuit is automatically switched to a waiting battery.

Description

External Charging Dual Power Electric Vehicles {.}

In the 21st century, air pollution and energy shortages are a serious problem in the world, and thus, the development of pollution-free electric vehicles is essential. The existing electric vehicle has a circuit that connects a number of batteries in series to supply electric power to the electric motor main motor ⑿ in a set, so that when the battery is discharged, it is recharged from the outside. It takes time (currently 3 to 5h) and there are many difficulties in realizing commercialization.

The present invention compensates for these drawbacks by dividing the battery, which is an electric vehicle power supply source, into two sets of power supplies to double the power supply. Is configured to automatically switch to a spare battery tank to supply stable power continuously. Also, the discharged battery tank is separated from the main power circuit automatically and then connected to the rotating shaft and belt of the car's rear wheel or main power motor and rotated. When the DC generated from the generator is recharged to the discharged battery tank in the standby state and the battery tank supplying power to the main power motor is discharged over the specified limit, the battery is automatically transferred to the standby battery repeatedly. Cabinet without charge It is a method of constructing a dual power supply circuit to enable distance operation.

In particular, when the main power motor is overloaded during mountainous operation, it detects this and automatically converts two sets of batteries into a parallel circuit, reducing the battery power burden in half, and automatically separating the generator from the main circuit. It minimizes the load and strengthens the overdischarge and climbing capacity of the battery.

As the representative drawing of the electric vehicle's power supply battery, the battery is placed as a battery and a battery, respectively, and when the battery that is supplying power to the main motor is discharged, the battery discharge sensor is detected and the Keep Ry is operated when the contact is closed. The main power supply circuit of the electric vehicle is composed of a circuit for automatic switching to a battery.The battery generator, which is automatically separated from the main power circuit, is connected to the main power motor or the rear wheel axle and belt of the vehicle to be rotated. It reconfigured to allow long-distance operation without external charging by repeatedly performing the function of recharging the DC generated in the standby to standby battery.

end. Power supply during electric vehicle flat driving (when power consumption is low)

When the plane is operating normally, the power will be supplied in the order of “B” contact → controller → power motor 모 of battery KKeep Ry⑽, and it is also connected to the rotating shaft and belt of the main power motor or the rear wheel and charged. Secure the reserve power supply from the generator → charge "b" contact of Aux1 to contact "b" of battery "K" → battery.

I. When the battery pack is over discharged when operating the electric vehicle flat

If the battery exceeds the specified discharge limit during operation, the battery discharge sensor "a" contact closure → OC coil excitation of Keep RyK → "a" contact closure of Keep RyK → closing → controllor → main motor motor The power supply is automatically switched from the battery to the battery to supply power, and the direct current generated from the rechargeable generator → → Aux1's “b” contact → Keep Ry's “a” contact closed → Battery Recharge to ensure reserve power.

All. When the battery is over discharged when operating the electric vehicle flat

If the battery exceeds the specified discharge limit during operation, the battery discharge sensor “a” contact closure → RC coil excitation of Keep Ry⑽ → “b” contact closure of Keep Ry → power supply in order from controller → main power motor. The circuit is automatically switched from the battery to the battery to supply good power continuously to the main power motor, and the direct current generated from the rechargeable generator → is transferred from the Aux1's "b" contact to "Keep Ry's" b "b. "Contact closed → Battery charging. Recharge in order to secure the reserve power.

la. Power supply for electric vehicle overload operation (mountain terrain and hill climbing, departure)

When the overcurrent flows to the main power motor due to mountainous terrain driving, etc., it detects the overcurrent Ry "a" contact closure → Aux1 coil excitation → Aux1 no. "A" contact closure → controller → main power motor ⑿ Battery supply circuit By automatically converting the battery and battery into parallel circuits, the battery current load is reduced to 1/2, and by opening the "b" contact of Aux Ry, the rechargeable generator is completely disconnected from the power supply circuit to minimize the main motor motor load. It is composed of dual power supply circuit that can withstand any overload.
