This part of GB/T 34570 specifies the safety of charger or charging unit used for charging in a conductive way the detachable or separable battery pack of motor-operated hand-held, transportable electric tools and lawn and garden tools powered by rechargeable battery.
This part is applicable to indoor or outdoor portable or fixed chargers or charging units supplied by mains supply at a voltage below single-phase a.c. 250 V.
This part also covers the requirements for the safety of chargers in battery tools which can be directly connected to mains supply or non-isolated power for operation and/or charging.
This part is not applicable to:
——Battery charging piles and charging devices used for electric vehicles;
——Charger of power supply unit used for electronic equipment;
——Charger of electronic flash equipment and power supply unit used for photography;
——Charger of battery used for toys;
——Battery charger used in special sites, e.g., sites with erosive and explosive gases (dusts, steams or combustible gases).

3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
Note: unless otherwise specified, the terms "voltage" and "current" refer to the effective values.
3.1
charger
part or whole of charging system contained in an independent shell, with the charger containing at least all energy conversion circuits
Note: in such a case, tools may be charged via a power cord or a built-in plug connected to power socket, an independent charger therefore does not necessarily contain all the charging systems.
3.2
conductive charge
the mode of charging the battery pack by making use of electrical conduction
3.3
d.c. distribution board
board of circuit capable of distributing direct current to socket or terminal
3.4
rated current
input current specified by the producer for the battery charger
3.5
rated input power
input power specified by the producer for the battery charger
3.6
rated output current
output current specified by the producer for the battery charger
3.7
rated output voltage
output voltage specified by the producer for the battery charger
3.8
rated voltage
input voltage specified by the producer for the battery charger
