Detailed Description

A battery abstraction.

The default battery model is ideal: It just takes the initial voltage value as its constant voltage value. This behavior can be changed by specifying a custom update function.

The battery handles a list of consumers. It updates itself after each simulation iteration. The update function takes the power loads for each consumer and current voltage value as inputs and returns a new voltage value.

Member Function Documentation

uint32_t AddConsumer

(

)

Returns

Unique consumer identifier.

virtual void Init ( )

virtual

Initialize.

void InitConsumers ( )

protected

Initialize the list of consumers.

virtual void Load ( sdf::ElementPtr  _sdf )

virtual

Load the battery.

Parameters

[in]

_sdf

Shared point to an sdf element.

std::string Name

(

)

const

Return the name of the battery.

Returns

The name of the battery.

bool PowerLoad	(	const uint32_t	_consumerId,
		double &	_powerLoad
	)		const

Get consumer power load in watts.

Parameters

[in]	_consumerId	Unique consumer identifier.
[out]	_powerLoad	Power load consumption in watts.

Returns

True if getting the power load consumption was successful.

const PowerLoad_M& PowerLoads

(

)

const

Get list of power loads in watts.

Returns

List of power loads in watts.

bool RemoveConsumer

(

const uint32_t

_consumerId

)

Remove a consumer.

Parameters

[in]

_consumerId

Unique consumer identifier.

Returns

True if the consumer was removed. False if the consumer id was not found.

virtual void ResetVoltage ( )

virtual

Reset the battery voltage to the initial value.

The initial value might have been loaded from an sdf element.

Load

bool SetPowerLoad	(	const uint32_t	_consumerId,
		const double	_powerLoad
	)

Set consumer power load in watts.

Parameters

[in]	_consumerId	Unique consumer identifier.
[in]	_powerLoad	Power load in watts.

Returns

True if setting the power load consumption was successful.

void SetUpdateFunc

(

std::function< double(const BatteryPtr &)>

_updateFunc

)

Setup function to update voltage.

Parameters

[in]

_updateFunc

The update function callback that is used to modify the battery's voltage. The parameter to the update function callback is a reference to an instance of Battery::UpdateData. The update function must return the new battery voltage as a double.

See Also

UpdateData

void Update

(

)

Update the battery.

This will in turn trigger the function set using the SetUpdateFunc function.

See Also

SetUpdateFunc.

virtual void UpdateParameters ( const sdf::ElementPtr  _sdf )

virtual

Update the parameters using new sdf values.

Parameters

[in]

_sdf

SDF values to update from.

double Voltage

(

)

const

Get the real voltage in volts.

Returns

Voltage.
