I assume that 'charge' refers to the build up of static electricity. Walk across a nylon carpet and touch someone, and a spark of static electricity will give both of you a shock.
Negative charge.
If an electrically uncharged body is contacted by an electrically charge body then the uncharged body will gain a charge. This is because electricity flows from a higher concentration to a lower concentration and will balance out.
To charge it positively placed a negatively charge body near it. The positive charge of the sphere is attracted near to the surface close to the negatively charge body. To make it completely positive just earth it (by touching it). This process is known as induction. To charge a body negatively is similar to the aforementioned method.

The cells in your body are in charge of your atoms.
If the cells of the body are metaphorically compared to rechargeable electric batteries, then what you do to charge them is to eat food; they run on nutrients.
The brain is actually in charge of many parts of the body. According my research, the brain is mainly in charge of sending messages to other parts of the body via nerves.
The body should have a charge of -20 (negative 20; one negative charge per electron). However such a species will be generally unstable unless there is a big charge separation.

to determine if there is a charge on an object/ body or not and what kind of charge as well.
The right half of the brain is in charge of the left side of the body.
