Abstract

The invention discloses a charging unit for a quick-change battery of an electric vehicle, an electric vehicle battery changing station and an energy storage station. The charging unit is used for charging the quick-change battery of the electric vehicle and comprises a charger and an electric connection seat which are arranged in a charging space, wherein the charger comprises a DC output interface which is electrically connected with the electric connection seat, and the electric connection seat comprises a high-voltage post terminal and is used for realizing electric connection with the quick-change battery. According to the charging unit, the length of a direct-current wire between the charger and the electric connecting seat is greatly shortened, wiring difficulty is reduced, and wiring cost is also reduced; on the other hand, the charger is directly connected with the electric connection seat in the charging unit, so electromagnetic interference among the charging units is avoided, and data transmission is more timely and accurate. In addition, each electric connection seat and each charger are arranged together in a centralized manner, and each charging unit is arranged separately, so the heat dissipation area is greatly increased, and damage of the charger caused by the temperature rise of the charger is further avoided.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a charging unit for a quick-change battery of an electric vehicle, a switching station for an electric vehicle, and an energy storage station. Background technique [0002] Traditional substations use centralized wiring. The charger is installed in a cabinet with a drawer layout. Each charging cabinet is equipped with 6-7 chargers, and each power station is equipped with 4-5 (or even more) charging cabinets. In order to save installation space, these charging cabinets are centrally arranged in a separate space of the entire power exchange station (this space is used to arrange power distribution and air conditioning devices), while the battery rack is arranged in another space of the power exchange station, called the charging room. Each charger in the charging cabinet outputs 2 DC output power cables and a set of charging control cables. [0003] figure 1 The layout of the...
