Embodiment Construction
[0018] According to attached figure 1 The schematic diagram and description of the circuit of the electric vehicle battery charger with multiple protection functions are shown, and the connection relationship between the components in each part of the circuit described in the summary of the invention, and the components described in the implementation mode The technical parameter requirements can realize the present invention by carrying out implementation.
[0019] Selection of components and their technical parameters
[0020] The following takes the 36V battery of an electric vehicle as an example:
[0021] For the full-bridge rectifier silicon stack QZ in the electric vehicle battery smart charger circuit, a plastic-encapsulated square 8-10A full bridge can be used, because the power of the silicon stack QZ is relatively large, it should be installed on an aluminum heat sink;
[0022] One-way thyristor SCR can choose 10A / 100V metal-encapsulated one-way thyristor, which c...

The invention belongs to the electronic technique field and storage battery charging, and relates to an intelligent charger for a storage battery of an electric vehicle. The intelligent charger for the storage battery consists of 220V alternating current, a power transformer T, a full-wave rectification circuit, a pulse direct current indicating circuit, unidirectional controllable silicon and a trigger circuit thereof, a biasing circuit of a PNP triode VT1, a charging output terminal and a charging state indicating circuit. The intelligent charger for the storage battery of the electric vehicle has multiple protective functions of preventing a polar plate of the storage battery from falling off or electrodes of the storage battery from being disconnected, preventing the storage battery from being subjected to short circuit, preventing inverted connection of a positive electrode and a negative electrode of the storage battery, preventing nominal voltage of a storage battery module from being deflected, preventing the polar plate of the storage battery from being subjected to lead sulfate formation, charging quickly, self-stopping until the storage battery is full of power and the like, so that a great convenience is supplied to a storage battery user; and the intelligent charger is suitable to be extensively used by an electric vehicle user and also suitable for developing charging and maintenance services in a shop or a stall.
Description
technical field [0001] The invention belongs to the technical field of electronic technology and accumulator charging, and relates to an intelligent charger for an electric vehicle accumulator. Background technique [0002] The large capacity and high cost performance of the storage battery are unmatched by various rechargeable batteries. At present, the batteries used in electric bicycles generally use maintenance-free lead-acid batteries as the power source, so the performance of the batteries directly affects the working performance of electric bicycles. Therefore, how to use and maintain batteries is the most concerned thing for consumers. Most of the battery chargers are supporting devices for electric vehicles. Although the battery is very tolerant to the charging method, if the inferior charger is used for a long time, the aging of the battery will be accelerated and the capacity will drop rapidly, which will lead to the shortening of the mileage of the electric bicy...
