Further, there is a limit to the power that can be supplied by the external power supply 50, and power is supplied within this limit. At this time, the outside air temperature is lower than the battery performance guarantee limit temperature, in other words, the temperature of the battery 11 is lower than the heater operation start temperature when left unattended.
- the required charge time extension amount required when the battery heater 15 is operated all the time is calculated and set in advance.
- the battery temperature check time is set to the front of the charging start time.

- the charging control device 21 determines that timer charging and battery heating are performed simultaneously. To do. That is, if battery heating has already been performed at a stage before the required charging time extension from the timer charging start time, the battery temperature is naturally below the heater operation stop temperature. High probability of operation. On the other hand, even if the battery is not heated, when the battery temperature is equal to or lower than the heater operation stop temperature, there is a high possibility that the battery heater 15 will subsequently decrease to the heater operation start temperature. In this case, the battery heater 15 operates.
- FIG. 7 is a flowchart showing a timer charging control process performed in the charging control apparatus according to the third embodiment.
- the required charge time extension amount which is a time that is advanced from the timer charging start time, is set based on the case where the battery heater 15 is continuously operated during charging. That is, the time when the advance of the necessary charging time is advanced coincides with the check time of the operating state and the battery temperature.

- step S42 battery temperature transition is predicted. Specifically, the battery temperature at the check time is set as an initial value, and an equation for calculating a temperature drop characteristic when the battery temperature falls to the outside air temperature is set. Then, how many hours later the battery temperature is reduced to the heater operation start temperature is predicted. On the other hand, after the battery heater 15 is activated, a prediction calculation is made as to how many hours later the battery temperature rises to the heater operation stop temperature. Thereby, it can estimate including the timing in which timer charge and battery heating are performed simultaneously.

However, if it is determined that it has not been reached, step S102 is repeated until it is reached.

Specifically, a predicted operation time at which the battery heater 15 is predicted to operate is calculated based on the predicted battery temperature. Then, the amount of power consumed obtained by the power consumption of the battery heater 15 multiplied by the estimated operation time is determined as the insufficient amount of charge power.

When it is determined that the timer charging has been reached, the process proceeds to step S92 to start charging, and when it is determined that the timer charging has not been reached, this step is repeated.
- FIG. 8 is a time chart showing the control process during timer charging according to the third embodiment.
- the initial state of this time chart shows a case where the user connects the external power supply 50 and the electric vehicle 100 by the charging cable 40 and the user sets the charging start time and the charging stop time of the interface device 25. Further, there is a limit to the power that can be supplied by the external power supply 50, and power is supplied within this limit.

- time t2 when the timer charge advance time is reached, timer charge is started. And although the battery heater 15 operates at the time t3, the full charge timing does not become after the time t4 which is the charge stop time. In other words, even when the battery heater 15 is activated, the fully charged state can be achieved at the charging stop time t4. Thereafter, when the battery temperature reaches the heater operation stop temperature at time t5, the operation of the battery heater 15 is stopped.

That is, when the battery heater 15 is operated only for a part of the timer charging time period, the charging start time is advanced by the amount of power consumption, so that the charging start time is not excessively advanced and the charge stop specified by the user is stopped. Charging can be completed on time.

Abstract
Description
ステップS1では、タイマ充電時間帯の予約の有無を判断し、予約がないときは本制御フローを終了し、予約があるときはステップS2へ進む。
ステップS2では、バッテリヒータ作動時の充電電力量不足分を計算する。具体的には、バッテリヒータ15の消費電力×充電時間で得られる消費電力量を計算する。
ステップS3では、計算された消費電力量を充電するための時間である必要充電時間延長量を決定する。
ステップS4では、予め設定されていた充電開始時刻を必要充電時間延長量分だけ早めた時刻を、バッテリヒータ15の作動状態チェック時刻として設定する。
ステップS5では、バッテリヒータ15の作動状態チェック時刻に到達したか否かを判断し、到達したと判断したときはステップS6に進み、それ以外のときは本ステップを繰り返す。尚、このとき、充電システムはスリープ状態であり、チェック時刻に到達すると、充電システムを起動して各種チェックを行う。
ステップS6では、充電システムを起動してバッテリヒータ15の作動状態をチェックし、バッテリヒータ15が作動中であればステップS8に進んで充電を開始し、停止中であればステップS7に進む。言い換えると、充電システムを起動する前のスリープ状態では、タイマのカウントによってチェック時刻に到達したか否かを判定しており、種々の状態チェックを行うメインの充電システムは起動していない。よって、充電システムのスリープ状態では、消費電力が極めて小さな状態とされる。
ステップS7では、予め設定されていた充電開始時刻に到達したか否かを判断し、到達したと判断したときはステップS8に進んで充電を開始し、到達していないときは本ステップを繰り返す。
(1)電気を充放電するバッテリ11と、バッテリ11を加熱するバッテリヒータ15と、バッテリ11の温度を検知するバッテリ温度センサ14(バッテリ温度検出手段)と、バッテリ11の温度状態を監視してバッテリヒータ15を制御してバッテリ加熱を行うバッテリ制御装置12(バッテリ制御手段)と、バッテリ11及びバッテリヒータ15に電力を供給する充電器22と、ユーザが所定の充電時間帯と目標充電量を任意に指定可能なインターフェース装置25(タイマ充電予約手段)と、インターフェース装置25により指定時刻までにタイマ充電を完了する指定が成されたときは、タイマ充電開始時刻を決定し、タイマ充電を行う充電制御装置21(充電制御手段)と、を備え、充電制御装置21は、タイマ充電とバッテリ加熱とが同時に行われると予測したときは、指定時刻までに充電が完了するように必要充電時間延長量を決定し、その分だけタイマ充電開始時刻よりも早く充電を開始することとした。
ステップS2では、バッテリヒータ作動時の充電電力量不足分を計算する。具体的には、バッテリヒータ15の消費電力×充電時間で得られる消費電力量を計算する。
ステップS3では、計算された消費電力量を充電するための時間である必要充電時間延長量を決定する。
ステップS41では、予め設定されていた充電開始時刻を必要充電時間延長量分だけ早めた時刻を、バッテリ温度のチェック時刻として設定する。
ステップS51では、バッテリ温度のチェック時刻に到達したか否かを判断し、到達したと判断したときはステップS61に進み、それ以外のときは本ステップを繰り返す。尚、このとき、充電システムはスリープ状態であり、チェック時刻に到達すると、充電システムを起動して各種チェックを行う。
ステップS61では、バッテリ温度をチェックし、バッテリ温度が閾値であるヒータ作動停止温度以下であればステップS8に進んで充電を開始し、停止中であればステップS7に進む。
ステップS7では、予め設定されていた充電開始時刻に到達したか否かを判断し、到達したと判断したときはステップS8に進んで充電を開始し、到達していないときは本ステップを繰り返す。
充電制御装置21は、タイマ充電開始時刻より必要充電時間延長量(所定時間)前において、バッテリ温度がヒータ作動停止温度(所定値)以下の場合、タイマ充電とバッテリ加熱とが同時に行われると判断する。
すなわち、タイマ充電開始時刻より必要充電時間延長量だけ前の段階において、既にバッテリ加熱が行われていた場合には、当然バッテリ温度はヒータ作動停止温度以下の状態であり、その後もバッテリヒータ15が作動する蓋然性が高い。一方、バッテリ加熱が行われていなくても、バッテリ温度がヒータ作動停止温度以下のときは、その後、ヒータ作動開始温度まで低下する可能性が高く、その場合にはバッテリヒータ15が作動する。そこで、タイマ充電とバッテリ加熱が同時に行われると判断しておけば、仮にバッテリヒータ15が作動していない状況があったとしても充電量が不足することがない。よって、充電停止時刻において充電量が不足することを回避することができる。
ステップS22では、バッテリ温度と、外気温度と、バッテリヒータ作動状態とをチェックするチェック時刻を設定する。このチェック時刻は、バッテリヒータ15の消費電力×充電時間で得られる消費電力量を計算し、計算された消費電力量を充電するための時間だけ、タイマ充電開始時刻よりも早めたタイミングである。
ステップS32では、チェック時刻に到達したか否かを判断し、到達したと判断したときはステップS42に進み、それ以外のときは本ステップを繰り返す。尚、このとき、充電システムはスリープ状態であり、チェック時刻に到達すると、充電システムを起動して各種チェックを行う。
ステップS42では、バッテリ温度推移を予測する。具体的には、チェック時刻におけるバッテリ温度を初期値とし、外気温度相当まで低下するときの温度低下特性演算式等を設定しておく。そして、何時間後にバッテリ温度がヒータ作動開始温度まで低下するかを予測演算する。逆に、バッテリヒータ15が作動した後は、更に何時間後にバッテリ温度がヒータ作動停止温度まで上昇するかを予測演算する。これにより、タイマ充電とバッテリ加熱が同時に行われるタイミングを含めて予測することができる。
ステップS72では、必要充電時間延長量を決定し、予め設定されたタイマ充電開始時刻から必要充電時間延長量だけ前倒ししたタイマ充電前倒し時刻を設定する。具体的には、充電電力量不足分を補うことができる時間を決定する。
ステップS82では、タイマ充電前倒し時刻に到達したか否かを判断し、到達したと判断したときはステップS92に進んで充電を開始し、到達していないと判断したときは本ステップを繰り返す。
(a)外気温度を検知する外気温度センサ26(外気温度検出手段)を有し、充電制御装置21は、タイマ充電開始時刻より所定時間前であるチェック時刻において、その時点のバッテリヒータ作動状態とバッテリ温度と外気温度とから、タイマ充電時間帯におけるバッテリ温度推移を予測し、予測されたバッテリ温度が予め設定されたバッテリヒータ作動温度範囲にあると予測した場合、タイマ充電とバッテリ加熱とが同時に行われると判断することとした。
ステップS2では、バッテリヒータ作動時の充電電力量不足分を計算する。具体的には、バッテリヒータ15の消費電力×充電時間で得られる消費電力量を計算する。
ステップS3では、計算された消費電力量を充電するための時間である必要充電時間延長量を決定する。
ステップS4では、予め設定されていた充電開始時刻を必要充電時間延長量分だけ早めた時刻を、バッテリヒータ15の作動状態及びバッテリ温度のチェック時刻として設定する。
ステップS54では、バッテリヒータ15の作動状態チェック時刻に到達したか否かを判断し、到達したと判断したときはステップS6に進み、それ以外のときは本ステップを繰り返す。尚、このとき、充電システムはスリープ状態であり、チェック時刻に到達すると、充電システムを起動して各種チェックを行う。
ステップS6では、バッテリヒータ15の作動状態をチェックし、バッテリヒータ15が作動中であればステップS602に進み、停止中の時はステップS601に進む。
ステップS602では、バッテリ温度が第2閾値以下か否かを判断し、第2閾値より高いときはバッテリヒータ15の作動が停止する蓋然性が高いと判断してステップS7に進む。一方、第2閾値以下のときは、まだバッテリヒータ15の作動が継続する蓋然性が高いと判断し、ステップS8に進んで充電を開始する。ここで、第2閾値は、ヒータ作動開始温度よりも高く、ヒータ作動停止温度よりも低い所定値であり、第1閾値よりも高い値に設定されている。
ステップS7では、予め設定されていた充電開始時刻に到達したか否かを判断し、到達したと判断したときはステップS8に進んで充電を開始し、到達していないときは本ステップを繰り返す。
