Abstract

The invention discloses a portable storage battery used for electric vehicles and a using method thereof. In the invention, by means of breaking up the whole into parts, the required voltage for driving an electric vehicle is subjected to layer-by-layer decomposition, and several low-voltage storage battery blocks are connected in series by a power line so as to achieve the required voltage. The portable storage battery is separable from electric vehicles and is convenient for vehicle owners to replace. The shell of the storage battery is provided with a power plug, by which the storage battery can be connected to an external charging device for charging. And the storage battery is characterized by a simple structure, convenience and rapidity. The using method of the above storage battery can realize rapid connection or separation of the portable storage battery and a storage battery box, change the traditional cumbersome battery replacing mode into a light battery replacing mode, thus avoiding the anxiety generated in vehicle owners due to the constant need of looking for a charging station, and not delaying the time and travel of the vehicle owners. The replaced portable storage battery is placed into a charging cabinet for charging during an off-peak period so as to avoid power consumption peak hours and reach the power using effect of load shifting from peak periods to off-peak periods in power grids.

Description

technical field [0001] The invention relates to the technical field of electric vehicle accessories and installation methods thereof, in particular to a portable storage battery for electric vehicles and a usage method. Background technique [0002] An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply, driven by a motor to drive the wheels, and conforming to the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. Batteries are the main energy source of electric vehicles. Various types of lead-acid storage batteries, nickel-cadmium storage batteries, nickel-metal hydride storage batteries or lithium batteries are commonly used in various electric vehicles in the prior art. Due to the wide variety of batteries and the relatively large number of voltage standards, and because electric vehicles use b...
